Warmest decade on record*

From NASA’s press release

NASA Research Finds Last Decade was Warmest on Record, 2009 One of Warmest Years

From NASA GISTEMP- Click image for original source

WASHINGTON — A new analysis of global surface temperatures by NASA scientists finds the past year was tied for the second warmest since 1880. In the Southern Hemisphere, 2009 was the warmest year on record.

Although 2008 was the coolest year of the decade because of a strong La Nina that cooled the tropical Pacific Ocean, 2009 saw a return to a near-record global temperatures as the La Nina diminished, according to the new analysis by NASA’s Goddard Institute for Space Studies (GISS) in New York. The past year was a small fraction of a degree cooler than 2005, the warmest on record, putting 2009 in a virtual tie with a cluster of other years –1998, 2002, 2003, 2006, and 2007 — for the second warmest on record.

“There’s always interest in the annual temperature numbers and a given year’s ranking, but the ranking often misses the point,” said James Hansen, GISS director. “There’s substantial year-to-year variability of global temperature caused by the tropical El Nino-La Nina cycle. When we average temperature over five or ten years to minimize that variability, we find global warming is continuing unabated.”

January 2000 to December 2009 was the warmest decade on record. Looking back to 1880, when modern scientific instrumentation became available to monitor temperatures precisely, a clear warming trend is present, although there was a leveling off between the 1940s and 1970s.

In the past three decades, the GISS surface temperature record shows an upward trend of about 0.36 degrees F (0.2 degrees C) per decade. In total, average global temperatures have increased by about 1.5 degrees F (0.8 degrees C) since 1880.

“That’s the important number to keep in mind,” said GISS climatologist Gavin Schmidt. “The difference between the second and sixth warmest years is trivial because the known uncertainty in the temperature measurement is larger than some of the differences between the warmest years.”

The near-record global temperatures of 2009 occurred despite an unseasonably cool December in much of North America. High air pressures from the Arctic decreased the east-west flow of the jet stream, while increasing its tendency to blow from north to south. The result was an unusual effect that caused frigid air from the Arctic to rush into North America and warmer mid-latitude air to shift toward the north. This left North America cooler than normal, while the Arctic was warmer than normal.

“The contiguous 48 states cover only 1.5 percent of the world area, so the United States’ temperature does not affect the global temperature much,” Hansen said.

GISS uses publicly available data from three sources to conduct its temperature analysis. The sources are weather data from more than a thousand meteorological stations around the world, satellite observations of sea surface temperatures, and Antarctic research station measurements.

Other research groups also track global temperature trends but use different analysis techniques. The Met Office Hadley Centre in the United Kingdom uses similar input measurements as GISS, for example, but it omits large areas of the Arctic and Antarctic where monitoring stations are sparse.

Although the two methods produce slightly differing results in the annual rankings, the decadal trends in the two records are essentially identical.

“There’s a contradiction between the results shown here and popular perceptions about climate trends,” Hansen said. “In the last decade, global warming has not stopped.”

    Yeah, but it’s GISTEMP so nobody is going to take it seriously.

  2. Andy in Christchurch NZ says:

    NIWA in New Zealand reported that the last decade was the “warmest on record” for NZ, but in fact it was a few 100ths of a degree warmer than the 80s and the 90s were cooler than both.

    This announcement was treated with a certain amount of disdain as a result, even in the mainstream media.

  3. Martin Brumby says:

    It certainly was a record decade for AGW bullshit.

  4. JohnH says:

    I’ve looked at their data for the Station nearest to me, Glasgow airport.

    1. It starts in 1880 which is 30 years before regular manned flight

    2. Raw data shows no warming trend at all over the full data

    3. The adjusted data shows the early years temps are adjusted downwards, later ones which are more likely to be affected by UHI are unadjusted.

    4. When looking at the stations used in Scotland they use mainly airports and sea level stations, odd considering Scotlands mountainous countryside and large rural unpopulated areas.

    Based on this I cannot believe a word these guys say

  5. TonyB says:

    * We measure from the end of the Little Ice Age and seem startled when temperatures increase.

    * We move thermometers and measure from Airports and seem startled when temperatures increase

    *We increase thermometer numbers then drop them from cool areas such as Russia then seem startled when temperatures increase

    *We urbanise most of the measuring points then disregard UHI and seem startled when temperatures increase

    The notion of a Global temperature is severely flawed in concept and execution, and the way it is measured and adjusted so inconsistent that these figures have little merit other than demomstrating the old adage that there are lies, damned lies and statistics.

    Very many individual stations around the world are showing a cooling trend-some for many years- demonstrating that the warming signal is being highlighted by the way the fgures are compiled.

    Tonyb.

  6. Jimbo says:

    After Climategate would you buy a car from these ‘used car salesmen’? Maybe they should have said:

    A new analysis of global surface temperatures by NASA scientists finds the past year was tied for the second warmest since 1880, according to the UHI records.

    In years to come we may have the makings of GISSgate or NASAgate.

  7. Torsten Wedin says:

    The last decade was the warmest decade this millenium, but when I think about it, also the coolest ;-)

  8. Ken Hall says:

    For all Hansen’s bluster, we know that they way they interpret the temperature data is designed from the outset to lower earlier temps and raise later temps. Taking thousands of stations from cold environments out of the record is bound to show a warming in the trend. If they keep going on like this, then the global temperature record for the 2050s will taken from one thermometer, surrounded by light focusing mirrors, in death valley California.

    What warming that there may have been is entirely within natural variability.

  9. Peter of Sydney says:

    Still a long way to go to match the Medieval Warm Period.

  10. Squidly says:

    Sorry, not believing it.

  11. evanmjones says:

    Airports are very damn lousy mesosites in spite of often favorable microsite attributes. In the US, airports have warmed much faster (by ~0.12C per decade) over the last 3 decades than well sited non-AP sites.

  12. Daniel H says:

    Speaking of broken records, Hansen is beginning to sound like one. Somebody please give this clown a new act.

  13. Nik Marshall-Blank says:

    James Hansen says “When we average temperature over five or ten years to minimize that variability, we find global warming is continuing unabated.”

    I interpret that as

    “After the little ice age which began in 1650 and ended in 1850 temperatures are finally returning to normal”

  14. So is averaging over 5-10 years enough now to talk about climate, according to Hansen himself? How strange…

  15. Robert E. Phelan says:

    I’ve just discovered that I am really no longer interested in anything GISS has to say. That whole “science” is simply no longer credible. We keep warning each other that the shenanigans of “The Team” were going to hurt science in general and climate science in particular… and I find myself now with neither interest or confidence in what one of the leading research organizations has to say.

    Maybe I’ve been hanging out here too long. ; )

  16. Leigh says:

    Considering the work of Anthony and others at surfacestations.org, the measurement errors and interpolation required for global temperature back in 1880, and the intervening UHI, that would be a 0.8 degree C increase +/- around 3.0 degrees C? I love the additional explanation and discussion regarding el nino, jet streams etc. It conotes an understanding more of the theory and models than of reality. They should report it in the newspaper, between the astrology section and the racing tips.

  17. Günter Hess says:

    NASA measured the warmest decade based on their temperature product that measures the mean global temperature anomalie with respect to 1950 to 1980. However, the weather didn’t change that much as we all observed. Doesn’t this mean that the weather of the earth is not very sensitive to global temperature anomalies.

  18. vg says:

    So Coleman’s TV report Part 4 was 100% correct! LOL

    “GISS uses publicly available data from three sources to conduct its temperature analysis. The sources are weather data from more than a thousand meteorological stations around the world, satellite observations of sea surface temperatures, and Antarctic research station measurements”

  19. Edbhoy says:

    JohnH
    I’ve looked at the unadjusted figures from Scotland for the stations that have been recording from 1930s up to 2008. The only one that shows any significant warming in the original data is Eskdalemuir . However once we correct for the “travesty” of lack of warming the picture changes substantially.

  20. Chris Schoneveld says:

    Even if “global warming stops” as from today for the next ninety years one can, at the end of this century, rightly claim that this was the hottest century of the last 500 years or so, yet it falsifies the run-away AGW hypothesis. Claims like: this is the hottest decade or the hottest century are meaningless, they are always used when upward trends stall or reverse, like we have seen this last decade

    “NASA Research Finds Last Decade was Warmest on Record”. Really?

    Well, here in Australia, we’re cool.

    “Looking back to 1880, when modern scientific instrumentation became available to monitor temperatures precisely”,

    the current decade in Australia is

    0.6-0.7 deg C cooler than it was in 1881-1890.

    This estimate is derived from the annual Mean Maximum Temperatures provided by the Bureau of Meteorology for the following meteorological stations:
    46043, 55023, 58012, 64008, 69018, 75031, 83025, 84016, 85096, 90015.
    These operational stations have temperature records back to 1881 or beyond.

    Not included in this analysis are the following long-standing stations based at airports or in major cities: 38003, 61055, 66062, 80015, 86071, 94029. Inevitably, local “urban warming (heat-island)” effects at these hot spots would have artificially inflated estimates. Indeed, they are on average 1 deg C warmer this century than previous highs. They rightly should be excluded from estimates of the true temperature trends across the country.

    So Dorothea MacKellar’s beloved “Sunburnt Country” was at least 0.6-0.7 deg C hotter during her early childhood than any other decade on record.

  24. Kaboom says:

    Look, you deniers, this is becoming serial!

    GISS data comes directly from NASA – yes, NASA, the people responsible for getting man to the Moon and back more than 40 years ago – so it must be an unimpeachable source of data.

    Once the NASA data are sifted through the intelligent, careful, and loving hands of Dr James Hansen, they become a tour de force of carefully adjusted real-world data.

    We really need to congratulate Dr James Hansen, Dr Keith Briffa, Dr Michael Mann, and others (and not forgetting our Mann of the Minute, Dr R.K. Patchauri), upon their valiant but ultimately unsuccessful attempt to prod (with a hockey stick) a reluctant bristlecomb pine fair up the [snip] of the World’s economy.

    Given the current, um, unrest surrounding the IPCC and their camp-following carpet-bagging sicophants, it is surprising that GISS has come up with these figures.

    However, if we consider that the “cake was baked” well prior to Hopenchangen, then this story is not in any way exceptional – indeed it was to be expected.

    Dr James Hansen, if you or one of your many acolytes are reading this, please be assured that we are indeed coming to get you.

  25. Ralph says:

    Of course it is was a warm decade, if you can massage the figures to say so. This is the Central England temperature record – largely raw data:

    I think people who can look at the long range climatological record as summarized in other GISS data are either not real scientists or are at the early stages of Alzheimer’s and should be pitied.

    There will always be a “warmest decade” or two before the inevitable down slides that the records show in the millenia long records.

  27. D. Patterson says:

    Hansen said. “In the last decade, global warming has not stopped.”

    More likely: In the last decade, global warming FRAUD by the Hockey Stick Team has not stopped.

    As long as people’s heating bills continue to rise, I doubt the news will be much consolation. Thinking it’s warm is not going to pay the oil or gas bill.

  32. MB says:

    The language suggests significant warming. But the numbers are tiny. 0.3 degrees here, 1.5 degrees there. Doesn’t anybody else think these “record temperatures” are infinitesimally close to the “non record temperatures”?

    I don’t understand why anybody is worried about this. On top of the fact that they are not actually claiming a significant temperature change, we know that the measurements are no good (urban heat Island, “hide the decline”) anyway.

    Then they come up with their “cluster of recent record high temperatures”. Why? Because it kind of supports their argument at first glance, as long as you don’t look at how small the numbers are.

    And of course, the recent cold spells, and they were *really* cold, a real difference that you could feel and were affected by, were just weather, not climate. This is a classic example of human bias creeping into analysis.

  33. Poptech says:

    Am I missing something here? How are these posts helping? No critique of the analysis, just reposting the NASA press release?

  34. MB says:

    PS I know that this so-called “independent data set” was not involved in the “hide the decline” statement, but the people involved in that are for all practical purposes the same group of people involved in this and from the emails we know their mindset, morals and ethics. I do not trust them to carry out unemotional, unbiased scientific analysis.

  35. David Alan says:

    I’m sorry you feel compelled to post this drivel.

    2009 produced massive extreme records not just here, but all over the world.
    All over the United States temperatures were well below normal. Extended periods of time had set records for precipitation, snow and highest minimums.

    I can only confirm that 2009 produced record extreme lows that outpaced extreme high temperatures and lowest maximums in over a decade.

    The Northern Hemisphere experienced record early snow and record snow cover.

    The plain states, the mid-west, and the great lakes region saw the coolest summer in over 80 years.

    In South America, certain populations saw snow for the first time in their lives.

    In Australia, new research confirms that temperature readings in the metropolitan areas trended higher than the villages in the outback , confirming UHI effects.

    And when it really comes down to it, the alarmism of Jim Hansen is about a few tenths of a degrees.

    We are witnessing a cooling process that which no living person has ever experienced.

    Period.

    2010 is already starting to prove one for the record books.

    Snow blankets the U.K.

    The Arctic sea ice is on pace to be above normal for a third straight year.

    And if I hear anymore alarmism in regards to sea level rise, I’m going to puke.

    With continental plate shifts and seduction and volcanism, how can we blame sea rise as nothing more than a natural phenomena.

    Jim Hansen and Gavin Schmidt are an embarrassment to science and should be removed from their profession.

    Until that day, WUWT readers will be forced to see similar posts, because the [snip] would only complain that WUWT favors the reports on cooling.

    Good Day !

    Fraud and/or stupidity?
    From a scientific point of view this NASA press release is another fraud of the public.
    We just escaped the aftermath of the Little Ice Age, lasting from 1350 to 1850.
    Since 2001 we are on a temperature plateau, with slightly decreasing temperature anomalies. Therefor all last 10 years belong to the 10 warmest since 650 years, (eventually the 1940ies might have been equally warm if manipulation of temperature anomalies could be ruled out).
    It is bad science from NASA to make a headline “warmest decade on record, 2009 second warmest”.
    Of course, this scientific fraud is taken up by the alarmist and anthropogenic warming supporting press with great enthusiasm.
    It is both fraud and stupidity!

    Most of the former sheep farms round Eskdalemuir have been turned into commercial spruce forests in the last 50 years. Would be surprised if this major land use change has not made a slight difference to the local climate.

  47. Baa Humbug says:

    Why does this man still have a job? Let alone feature prominently in press releases.

    Hansen (you agenda driven truth hiding) poor excuse for a man. A thousand curses on you and yours (I wish I could swear)

  48. John Trigge says:

    Step 1 of the GISS analysis method contains:

    “Non-overlapping records are viewed as a single record, unless this would
    result introducing a discontinuity; in the documented case of St.Helena
    the discontinuity is eliminated by adding 1C to the early part.

    After noticing an unusual warming trend in Hawaii, closer investigation
    showed its origin to be in the Lihue record; it had a discontinuity around
    1950 not present in any neighboring station. Based on those data, we added
    0.8C to the part before the discontinuity.”

    I am not a ‘climate scientist’ but the adding of ANY values to the ‘data’ seems a bit non-scientific to me.

  49. gerard says:

    Are these adjusted figures?

  50. Peter of Sydney says:

    I’m still wondering what the problem is. The “officially” recognized warming over the past 100+ years is still well within normal operational parameters of natural climate change. Therefore, it’s clear that man has very little resultant impact if any on climate. To say otherwise actually goes against the latest observed results produced by NASA.

  51. Jimmy Haigh says:

    David Alan (01:44:28) :

    “With continental plate shifts and seduction and volcanism, how can we blame sea rise as nothing more than a natural phenomena. ”

    Should be “subduction”.

  52. Nik Marshall-Blank says:

    And I’ll bet that the reason all the temperature records look the same even from different “official” sources is that if one of them produced a graph showing the truth their work would have been discredited and the funding discontinued.

    So they all probably adjusted the data so as to produce graphs like the “officially accepted ones”.

    And in reponse to Trigge, subtracting 0.8 from the higher value to match a discontinuous previous value is just as valid as adding to the previous to “hide” the discontinuity.

    Why didn’t they do 50% additions and 50% subtractions and smooth the result?

  53. KPO says:

    Robert E. Phelan (00:38:05) :

    Robert, I am also beginning despair. If a scientist told me that water was wet, I’d now have a hard time believing it. Sadly, that elevated status we once believed was almost “god-like” is now degenerating to the level of suspicion preciously reserved for used car and door to door vacuum cleaner salesmen. Actually in comparison, the salesmen appear to be pillars of virtue. Such a decline – and it’s a travesty we can’t explain it.

    GISS shows + deg C anomaly for Central Europe.
    Our only truly rural station, Lomnicky stit observatory, shows 51-80 base period 0.7 deg C colder than 1998-2008.
    So GISS is only 0.3-1.3 deg C off mark.

  57. David says:

    There is no end to their mendacity. The Mercator projection they use conveniently distorts the representation of land area so that the allegedly warming polar regions appear far bigger than they really are. And I like the idea of Antarctic measurements – plural measurements, singular station.

  58. ghw says:

    Just for the records:

    A decade starts with year xxx1 and ends with year xxx0 (Just compare it to the “official” reference-period: 1951-1980)

    So, since we haven’t finished the current decade yet, there is no warmest decade on record.

    And if you take a look at the true data: http://data.giss.nasa.gov/cgi-bin/gistemp/do_nmap.py?year_last=2009&month_last=12&sat=4&sst=0&type=anoms&mean_gen=0112&year1=2000&year2=2009&base1=1951&base2=1980&radius=250&pol=reg you will see, which kind of swiss cheese the warmest decade on record really is…

    So much agenda, so little time.

    So, if we could reduce the ocean blip by, say, 0.15 degrees Celsius, then this would be significant for the global average—but we’d still have to explain the land blip. – Tom Wigley (and yes I know he is not NASA)

  64. Colin Porter says:

    Looking at the image of temperature anomalies, it seems to me that the majority of warming anomalies are concentrated over land, while the sea areas excluding the Arctic generally show very slight cooling, no change or very slight warming. The land based data are from suitably homogenised and adjusted weather stations whilst the sea based data come from satellite measurements, not withstanding the fact that the satellite era only commenced in 1979 while the anomalies are against a 1951-80 average.

    It seems to me that there are two possible explanations for this.

    1. The land based data has been corrupted with UHI and other “adjustments.”
    2. The anomalies are correct and therefore the sea is now cooling as compared with the land and that with its much greater heat content, it is an indication that the warming period has come to an end and we can expect a sustained period of stable temperatures or even cooling.

    Whichever explanation is true, should it not be the duty of Mr Hansen to explain this difference in his summary?

    Taking this analysis a stage further, is the best compromise for a global temperature just simply the satellite based sea surface temperature? All the land based data have been corrupted with UHI and other adjustments and the guardians of these data sets acknowledge that complete coverage is not a requirement by way of them having deleted the vast majority of weather stations anyway. Likewise the UAH and RSS records are of the lower troposphere and therefore are only a proxy for what is happening at ground (or sea) level.

  65. Missing the point says:

    You are all missing the point….
    The general public doesn’t want scientific truths, they want someone to tell them what is happening and all most have is the MSM which loves to report ‘records’. In a few months from now many people will honestly, if misguidedly, say at parties, in coffee shops and pubs or round the water cooler that the last decade was the warmest on record. They won’t remember where they read or heard it and that won’t matter because they will have integrated it into their world view and it will be as good as a fact to them and all they dispense the information to.
    When the climategate furore dies down, which is dependent on how long the dedicated people who run sites like these can keep up the amount of work needed to keep it current, what people will remember is the ‘record decade’. The only thing keeping us all from the CTS scams is the dedication of volunteers at WUWT, CA and others and that is a finite resource. Remember, what the general public sees is so-called ‘respected scientists’ from major institutions who are obviously passionate about their work and appear to truly believe in it – that is a strong message whether it is true or not.
    I continue to keep my fingers crossed that the truth is revealed and this craziness will come to an end but the longer it goes on, the more concerned I get that the luddites will eventually triumph.

    Sorry for the rant, I am not diminishing any of the commenters on here, I think there are many valid points made by people smarter than me, I just don’t think the GP cares and I speak as a non-scientist who believes we are about to flush civilization down the toilet so I would love to be proved wrong.

  70. Woodsy42 says:

    But sadly, as with most ‘alarmist’ propaganda, this is the story that the media will peddle.

    We may know this data has been fiddled and I have no doubt honest scientists here and across the web will put this report into a proper perspective. But to my mind a huge problem remains. No amount of self-congratulation here about our ability to see the truth, and no amount of honest science discussed here, will do much to correct the propaganda message which the public and politicians will hear and continue to follow.

    In almost all cases the ‘alarmists’ are still being allowed to make all the plays. Not only does alarmism sell but the whole AGW debate is being played completely to their rules. They make an often ridiculous claim then we moderates, sceptics and realists end up playing catchup. Even good spokesmen like Lord Monckton or Christopher Booker are forced to pedal a mainly negative message simply rebutting the extreme claims. Because the realists need to be careful to stay absolutely within the true science and be honest they can only defend, they have almost nothing to attack with.

    I think someone needs to fight the ‘warmist’ dishonesty by their own methods, we need some good publicity-attracting scare stories of our own that can be fed to the media. Wind generators shredding a few birds or blighting the view are not bad enough. We need some headline grabbing stories to detail and underline the serious problems that might happen if we follow the ‘alarmist’ agenda. We need to play by their rules and start populating their playing field with some real scary downsides.

    I guess Anthony may not approve of ‘misusing’ science even in a good cause to get our own back so it wouldn’t be done here. But even so a couple of things come to mind. Rather than us realists just saying ‘Carbon trading will impoverish us all’ have any social economists tried to predict how a US or UK family might live in 2100 in abject poverty with limited carbon credits and all jobs outsourced to India and China?
    On a science tack, what’s the chance that windfarms may cause ground vibrations which increase earthquake risks? This is just as true as some of the extreme ‘warmist’ nonsense we hear and carries a common sense value making it very hard to completely debunk as an idea. Has anyone even thought about it?

  71. keith in Hastings UK says:

    To those who query why this report was posted: folk such as I NEED to see what rubbish the AGW church is posting, so we can be alerted to the MSM coverage which will follow, and can do our best to debunk it with our circle of friends and aquaintences.
    I mostly get shouted at, of course, because far too any still believe the AGW hysteria; regarding MSM like the BBC, and institutions like the UN, as authoritative. They just don’t believe that the data and analysis is crap, and take the band wagon of politicians as showing it must be true. Still, progress here and there: keep blogging, emailing, talking in Pubs (bars), writing to politicians etc. Emphasise what else the £ & $ could be used for!

    However, the statement that the warming stopped in the last decade means that the trend is zero or negative in the 2000-2009 interval, which is an entirely different statement. And it is true.

    The Met office has just sneaked out its ownHadCrut3 annual data
    here
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/nh+sh/annual

    But the December 2009 monthly data is still missing.

    No announcement, maybe because it does not agree with the GISS data. Hiding the decline maybe?

    Anyway, HadCrut3 shows a variance of 0.439c (different base line from GISS) which makes it the 5th warmest on record:
    1: 1998
    2: 2005
    3: 2003
    4: 2002
    5: 2009

    GISS make it the 2nd warmest on record, mainly because they paint the whole of the antarctic and arctic at the same temperature as their nearest temp stations. HadCrut3 ignores the poles as the land based data is so sparse.

    Interestingly the satellite record (University of Alabama Huntsville series) shows 2009 to be the 7th hottest in its record. Its ranking is;
    1: 1998
    2: 2005
    3: 2002
    4: 2007
    5: 2003
    6: 2006
    7: 2009

    Now the UAH data [i]does[/i] include the poles, and so does not need to guess for missing information. So in terms of believability I would rank the studies as:

    1: UAH
    2: HadCrut3
    3: GISS

    The grand experiment continues. Mankind continues to add carbon dioxide to the atmosphere. Even before the debacles of Copenhagen and Climategate, the largest generators of carbon dioxide were not going to cut back.

    Cap and Trade is dead. Kyoto is going to be dead, not that it matters.

    Whatever our views on AGW, mankind will continue to pump CO2 into the atmosphere and the earth will do what it will.

    My guess? And this is a guess because I don’t know what is really going to happen until it does.

    I think the sun drives our climate, directly or indirectly. Until the sun decides to crank up again, we will be in the short term cooling trend we have seen since 1998. Over the next century, possibly a continuation of the gradual warming we’ve seen since 1850. But here’s the big question, will the earth do another 1940 to 1975 cooling or will the current short term cooling trend become a Dalton type cooling?

    Time will tell.

    I actually applaud this sort of rubbish being publicised. The more there is of it the more the whole AGW business looks ridiculous to the general public.

    The fact is that AGW took off in the public consciousness because it did get warmer and we had some hot summers and not very cold winters.

    The cause of the warming escapes many people and many journalists and even some scientists or ‘scientists’. But if the cries of ‘wolf, wolf, there really is a wolf this time honest’ continue during a period of obvious hemisphere wide cold the AGW camp just make themselves look ridiculous.

    There is more to come, much more. If we really do have a few cool/cold years to come then:

    The ‘melting ice caps’ will expand again.
    There will be an impact on agricultural prices because of frost damage and crop failures.
    Some more brutal winters etc

    None of this is to be welcomed but it might be what happens.

    At the moment the dominant generation are people who grew up when it was colder than in recent years. Fast foward a few years and we might have a generation with memories of it being a lot warmer when they were growing up.

    All of this is beside the point for the causes of warming and cooling but it is very relevant to public perception.

    They can’t make a claim for the decade until the decade is over. The current decade started on 1 Jan 2001 and will end on 31 Dec 2010, more than 11 months away.

    Just because the general public can’t get it right doesn’t mean scientists should go along with them.

    I know many climate scientists have a problem with this concept but science is not majaority rules. Science is facts. And the fact is there was no year 0 AD (or whichever system you want to use), so the first decade was 1 Jan 1AD to 31 Dec 10AD. Therefore every decade since ENDS with the year that ends in zero (10, 20, 30,.. 1990, 2000, 2010), decades don’t START with years that end in zero.

Now this press release pegs 2005 as warmest on record, which wasn’t even in the top ten back then, just a few years ago.

    And now in the “virtual tie” for second warmest are 1998, 2002, 2003, 2006, 2007, and 2009. In that corrected top ten list reported in 2007, the only 200x year was 2006, with the original list having only 2001 and 2006. How did all those 19xx years get bumped off?

    Anthony

    Re: NASA press release: ‘NASA Research Finds Last Decade was
    Warmest on Record, 2009 One of Warmest Years’

    1. Pardon my repeating a point that I have made before!

    2. I quote from the NASA press release:

    ‘GISS uses publicly available data from three sources to conduct
    its temperature analysis. The sources are weather data from more
    than a thousand meteorological stations around the world,
    satellite observations of sea surface temperatures, and
    Antarctic research station measurements.

    Other research groups also track global temperature trends but
    use different analysis techniques. The Met Office Hadley Centre
    in the United Kingdom uses similar input measurements as GISS,
    for example, but it omits large areas of the Arctic and
    Antarctic where monitoring stations are sparse.

    Although the two methods produce slightly differing results in
    the annual rankings, the decadal trends in the two records are
    essentially identical.’

    3. What NASA does not say is that Climategate has so shaken
    public confidence in the ‘different analysis technique’ of the
    Met Office Hadley Centre that on 5 December 2009 eg the UK
    Daily Telegraph reported:

    ‘Scientists may re-examine temperature data to prove climate
    change

    Climate scientists may re-examine 160 years of temperature data
    after admitting that public confidence in the reality of global
    warming has been undermined by ‘climategate’.

    To try to restore public confidence the Met Office is talking to
    other meteorological organisations around the world about
    recreating the model using the same raw data but more modern
    computers.

    The whole process will also use any new information and be more
    open to the public.

    However, it could take up to three years for the study to
    complete, meaning the scientific world would have to wait until
    after 2012 to provide updated proof of the extent of global
    warming.’

    4. The Times reported the same story, but also added:

    ‘The Government is attempting to stop the Met Office from
    carrying out the re-examination, arguing that it would be
    seized upon by climate change sceptics.’

    and in a later story the same day the BBC reported:

    ‘An MO spokesman denied it would spend up to three years
    re-examining the climate change data’.

    5. But the UK Government has now survived Copenhagen. So
    we can ask again: Did the words ‘the Met Office is talking to
    other meteorological organisations around the world’ include
    NASA GISS?

    If so, NASA GISS can no longer rely upon the Met Office Hadley
    Centre’s present analysis.

    And NASA GISS was wrong, by the words ‘Although the two methods
    produce slightly differing results in the annual rankings, the
    decadal trends in the two records are essentially identical’,
    to imply, without substantial qualification, that it
    nevertheless does still rely upon the corroboration of the
    findings of the NASA GISS analysis by the findings of the
    Hadley Centre analysis.

    UAH -0.05 ; 0.06 ; 0.22

  109. Steve in SC says:

    From the Laws page on the Number Watch Site:

    Langmuir’s Laws of bad science

    1 .The maximum effect that is observed is produced by a causative agent of barely detectable intensity, and the magnitude of the effect is substantially independent of the intensity of the cause.

    2. The effect is of a magnitude that remains close to the limit of detectability, or many measurements are necessary because of the low level of significance of the results.

    3. There are claims of great accuracy.

    4. Fantastic theories contrary to experience are suggested.

    5. Criticisms are met by ad hoc excuses thought up on the spur of the moment.

    6. The ratio of supporters to critics rises to somewhere near 50% and then falls gradually to zero.

    First of all, the LAST decade was from 1991 through 2000. The CURRENT decade started in 2001 and ends on December 31 (11:59:59 PM) of this year. The next decade begins at 12:00 AM on January 1, 2011.

    Second, we all know GISS uses a different (lower) baseline, so the temperature anomaly is higher than other measurements such as UHA.

    Third, the records back to 1880 aren’t complete enough.

    “warmest” or really “not as cold”? In this data has the summer temperatures actually gone up? Or are the winters less cold? That’s what I’m finding. (see http://www.scribd.com/doc/25338819/What-Does-Averge-Temperature-Actually-Mean#stats)

    REPLY: Yes

  114. Claude Harvey says:

    Most respondents to this site have seemed to like Roy Spencer’s monthly satellite record of the global temperature anomaly at 14,000 feet, especially after it dipped down to essentially zero in year 2,000. Well, take another look at that chart. It certainly shows the past decade to have been the warmest in the thirty or so years satellites have been taking those measurements. When Spencer publishes the January, 2010 anomaly, brace yourselves for a shocker because the thing is sailing well above any comparable January in the past.

    It is a mistake to let “Hansen hatred” addle one’s brains to the point that one forgets what the real controversy is all about. Which modern decade may have been the warmest is NOT the fundamental issue at stake in the AGW challenge. Although I see ample evidence the GISS numbers are not to be trusted, I see no such evidence against the satellite record. It seems to me the satellite record probably adds weight to Hansen’s most recent pronouncement and thus demonstrates the ancient truism that “Even a blind pig can occassionally find and acorn.”

    The data behind climate science has lost all credibility and the CAGW hypothesis falsified.

    Example from the link:

    “It seems that stations placed in historically cooler, rural areas of higher latitude and elevation were scrapped from the data series in favor of more urban locales at lower latitudes and elevations. Consequently, post-1990 readings have been biased to the warm side not only by selective geographic location, but also by the anthropogenic heating influence of a phenomenon known as the Urban Heat Island Effect (UHI).

    For example, Canada’s reporting stations dropped from 496 in 1989 to 44 in 1991, with the percentage of stations at lower elevations tripling while the numbers of those at higher elevations dropped to one. That’s right: As Smith wrote in his blog, they left “one thermometer for everything north of LAT 65.” And that one resides in a place called Eureka, which has been described as “The Garden Spot of the Arctic” due to its unusually moderate summers.”

    Bad science being exposed.

    John Finn,

    The fraud if it exists is in the ‘early’ records or more accurately…the comparison to the earlier records.

    The Glaciers on Mt Rainier are the most studied glaciers in the world. The only thermometer I trust.
    http://www.nps.gov/archive/mora/ncrd/glaciers.htm

    Between the 14th century and A.D. 1850, many of the glaciers on Mount Rainier advanced to their farthest..Retreat of the Little Ice Age glaciers was slow until about 1920 when retreat became more rapid…Beginning in 1950 and continuing through the early 1980′s, however, many of the major glaciers advanced…Since the early-1980′s and through 1992, however, many glaciers have been thinning and retreating and some advances have slowed.

  122. r says:

    One has to wonder,

    Are researchers contaminating their own data? Is the recorded temperature of Antarctica higher because of the heat the researchers generate? Are the coral dying because of the sunscreen researchers wear? Are frogs dying of bacteria brought to remote areas on the shoes of researchers?

    I agree with Claud Harvey and the others, just because GISS is a mess it does not mean it can’t be right twice a day, like a broken clock. We should only laugh at GISS if our weapon of choice, UAH, contradicts GISS wildly.

    It looks like UAH & GISS may not be too far apart. Which means GISS despite its incredibly unbelieveable infill is coming up with the goods (that stuck in my throat).

    So…….do we now diss UAH or look to a reason.
    Is it the oceans actually giving up the heat in the pipeline, a possible short term affect and thus the sign of impending cold? Or is the atmosphere actually getting warmer, a result of El Nino on top of a couple of LA Ninas making the anomaly high. Or is it the dreaded CO2 after all. I still can’t buy the idea of CO2, it would be all to convienient to the politics in play. But in truth the world has not chilled enough to ‘basket’ the 90s EL Ninos…its dropped a gnats and plateaued.
    Is this still the ongoing warming from the LIA?
    So many questions.

  125. Ken G says:

    Hansen says:

    “There’s substantial year-to-year variability of global temperature caused by the tropical El Nino-La Nina cycle. When we average temperature over five or ten years to minimize that variability, we find global warming is continuing unabated.”

    The NOAA disagrees.

    http://www.ncdc.noaa.gov/oa/climate/research/2008/ann/bams/full-report.pdf

    NOAA report: State of the Climate in 2008, pg 24

    “El Niño–Southern Oscillation is a strong driver of interannual global mean temperature variations. ENSO and non-ENSO contributions
    can be separated by the method of Thompson et al. (2008) (Fig. 2.8a). The trend in the ENSO-related component for 1999–2008 is +0.08±0.07°C decade–1, fully accounting for the overall observed trend. The trend after removing ENSO (the “ENSO-adjusted” trend) is 0.00°±0.05°C decade–1, implying much greater disagreement with anticipated global temperature
    rise.”

    1999-2008 saw an ENSO adjusted trend of 0.00c. Obiviously, this period being analyzed is one year earlier than Hansen is talking about, but 2009 was also an El Nino year, which began in June, so I doubt the ENSO adjusted trend changed much.

    Hansen also says:

    “Other research groups also track global temperature trends but use different analysis techniques. The Met Office Hadley Centre in the United Kingdom uses similar input measurements as GISS, for example, but it omits large areas of the Arctic and Antarctic where monitoring stations are sparse.

    Although the two methods produce slightly differing results in the annual rankings, the decadal trends in the two records are essentially identical.”

    Well the NOAA analysis above was done using HadCrut3 Data, which does not suggest that after adjusting for ENSO that “global warming is continuing unabated”.

    Also, I find it interesting that Hansen never actually quantifies the last decade in this release. He talks about the last decade but only quantifies longer trends, and ignores actually putting a number to the claims about the last decade. I wonder why.

  126. Manfred says:

    John Finn (05:48:27) :
    UAH -0.05 ; 0.06 ; 0.22
    GISS -0.06 ; 0.08 ; 0.28

    the UAH measured troposphere should warm faster than GISS, indicating a warming bias of approx. 0.1 deg or 30%. If this bias is attributable to land only, the land warming bias would be around 100%.

    add similar bias due to the downward correction before the satellite era, or more, as there is no crosscheck possibility, making that period ideal to hide the decline.

    then the question arises – where the heck is the warming since the 1930s ?

    By the way, some real warming wouldn’t be bad, but I just don’t want man-made warming to be a result of the way it is recorded and adjusted, even if the record doesn’t show any warming.

    John Finn (05:48:27) :
    I’ve just been checking the decadal averages for both GISS and UAH over the past ~30 years. To provide a fair comparison I’ve used the satellite period (1979-1998) as the base period for the anomalies.

    The respective decadal average anomalies for 1980s, 1990s & 2000s are as follows:

    UAH -0.05 ; 0.06 ; 0.22
    GISS -0.06 ; 0.08 ; 0.28

    I am yet to be convinced that GISS are guilty of large scale fraud.

    I just checked the period from 2003. I chose 2003 because UAH started using AQUA in 2003, so the last 7 years has the most reliable satellite measurements. Hadcrut is missing data for the last couple of months, but at least for the given data, the downward trend is almost identical to that of UAH, while GISS is almost flat:

    I have a new way to measure global warming locally. Last winter in Hawaii, by this time I had worn pajamas to bed 12 times, this year? Only 6 times. So it is 50% warmer here this winter. OMG! We’re doomed!

    On a more sane note, in 1992 we had Hurricane Iniki which strengthened over warmer tropical waters (EL Nino Effect). Since then, the ocean temps have cooled around Hawaii and hurricanes typically die out before reaching us. If waters were warming, you would see many more hurricanes striking land in the middle of the Pacific. I am interested to see what happens with the El Nino over the next few Hurricane seasons but this is one way you can check against the claims of the alarmists.

    Ask NOAA:
    “Sep. 10, 2007: The year 2000 version of USHCN data was replaced by the current version (with data through 2005). In this newer version, NOAA removed or corrected a number of station records before year 2000. Since these changes included most of the records that failed our quality control checks, we no longer remove any USHCN records. The effect of station removal on analyzed global temperature is very small, as shown by graphs and maps available here.

  141. Herman L says:

    Anthony,

    And what in your posting is the definition of something that cannot be “trusted?”

  142. Richard S Courtney says:

    Friends:

    So, the article reports that NASA GISTEMP says;

    “January 2000 to December 2009 was the warmest decade on record. Looking back to 1880, when modern scientific instrumentation became available to monitor temperatures precisely, a clear warming trend is present, although there was a leveling off between the 1940s and 1970s.”

    and James Hansen asserts;

    “There’s substantial year-to-year variability of global temperature caused by the tropical El Nino-La Nina cycle. When we average temperature over five or ten years to minimize that variability, we find global warming is continuing unabated.”

    OK, for sake of argument, let us accept the above statements as being true (although they are extremely dubious as the leaked CRU emails prove) and consider what they mean if they are true.

    The NASA GISTEMP “record” is very short and dates from about 1880. But several studies indicate that the globe has been warming from the Little Ice Age since about 1700 (e.g. Beltrami et al “Long-term tracking of climate change by underground temperatures”, Geophysical Research Letters v.12 (2005) )”. Importantly, global temperature has fallen since its peak in 1998. Hence, of course recent global temperatures are among the “hottest” recorded.

    Using “average temperature over five or ten years “ hides the decline since 1998. Indeed, it is a statistical trick to hide the fact that the GISTEMP record shows no statistically significant warming since 1995.

    Of course the most recent decade is warmer than any other in the GISTEMP ”record”. Similarly, a person who walks up a mountain is still high soon after he has started down the other side.

    Importantly, it is worthless information that the GISTEMP global temperatures averaged over decades shows the most recent decade to be the hottest. At issue is why temperature rose through the twentieth century and has shown no significant rise recently.

    Indeed, there is good reason to anticipate that the fluctuations around a value of global temperature of the last decade will continue for another two decades. This is because the climate varies in cycles that are overlaid on each other, and two of them are worthy of especial note.

    There is an apparent ~900 year oscillation that caused the Roman Warm Period (RWP), then the Dark Age Cool Period (DACP), then the Medieval Warm Period (MWP), then the Little Ice Age (LIA), and the present warm period (PWP). All the observed rise of global temperature in the twentieth century could be recovery from the LIA that is similar to the recovery from the DACP to the MWP: indeed, there is no reason to suppose the causes of these two warming periods differ.

    And there is an apparent ~60 year oscillation that coincides with variations to the Arctic Oscillation (AO) and the North Atlantic Oscillation (NAO). This caused cooling to ~1910, then warming to ~1940, then cooling to ~1970, then warming to 1998, then cooling since.

    So, if these cycles continue when the ~60 year oscillation returns to a warming phase around 2030 either warming will resume until the globe reaches temperatures of the MWP, or cooling will continue until the globe reaches temperatures of the LIA.

    Hence, the fact that it has been warm in the last decade tells nothing about whether it will get warmer or colder in the next few decades. All sensible people will hope for warming.

  143. DirkH says:

    We have to expose the thermometer genocide and the rewriting of the past of GISS to discredit NASA’s “warmest” claims.

    ““There’s a contradiction between the results shown here and popular perceptions about climate trends,” Hansen said. “In the last decade, global warming has not stopped.””

    Except that Hansen does not seem to realize (or care) that the issue hasn’t been the last decade for some time. It is now something like twelve years.

  146. RomanM says:

    From the press release:

    The past year was a small fraction of a degree cooler than 2005, the warmest on record, putting 2009 in a virtual tie with a cluster of other years –1998, 2002, 2003, 2006, and 2007 — for the second warmest on record.

    Since all these years are in a”virtual tie”, I read this as an explicit admission by NASA that there has not been any “significant” warming for 12 years!

  147. A bit off topic, but Richard Black, BBC hero, has managed to assess the state of climate politics, without even mentioning climategate.

  148. Viv Evans says:

    Assuming that Hansen et all are right, and that its all ‘settled’, I find it irritating when scientists (even if it is for a press release) blather about how its getting ‘warmer’ – and the actual numbers are tiny, like ~0.8F.
    Yes, that would be ‘warmer’ than ~.2F – but how does it compare to the previous alarms about temperatures rising by 6C?
    It is also irritating when those scientists just throw numbers around, without indicating the units they are talking about. There is, to my certain knowledge, a slight difference between 1F and 1C …

    And I find it irritating when people go on about how ‘we’ put so much CO2 into the atmosphere.
    I seem to recall that there is a lag of 800 years between a warm period and subsequent rise of CO2. So isn’t the rise we’re seeing the result of the MWP? Or am I missing something?

  149. Tom in Florida says:

    A year or so ago, perhaps two, a poster asked if the communications transmissions we all use would have any effect on the air temperatures.

  150. Barry Hoffman says:

    “Warmest Decade” measured from ground based stations offers too much variability. Historically we have to account for the urban warming effect, loss of reporting stations in very cold climates, and “smoothing” to fill reporting holes that doesn’t account for altitude variability. The thermal inertia to warming of the oceans is potentially the only reliable source of comparison. What does that data set tell us?

  163. John Theon speaks out:

    “In a 37-year career at NASA, his titles included Chief of the Atmospheric Dynamics, Radiation, & Hydrology Branch followed by a stint as Chief of the Climate Processes Research Program at NASA HQ.”

    “As Chief of several of NASA Headquarters’ programs (1982-94), an SES position, I was responsible for all weather and climate research in the entire agency, including the research work by James Hansen, Roy Spencer, Joanne Simpson, and several hundred other scientists at NASA field centers, in academia, and in the private sector who worked on climate research,” Theon wrote. “I appreciate the opportunity to add my name to those who disagree that global warming is man made.”

    “My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit. Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it.

    “They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy.”

    “Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress.”

    I have always wondered why the RAWS system in the US is not incorporated into UHI evaluation checks. I would love to see a screen with overlays for weather data for ASOS locations and then compare to the nearest RAWS and the nearest long term surfacestation.

    It provides a check for each of the official stations used. A way to view weather changes, by the reports from the different major systems not included in the climate models. It provides the best set of tools to measure “UHI”. The equipment is perfectly situated to show heating or cooling trends in wilderness interface locations.

    The Remote Automated Weather System has been installed in about 2,200 remote locations all over the US. It is continuously updated and upgraded with new hardware as technology advances. The locations are specifically picked to provide timely information about the “Wilderness” for fire science.

    If its good enough for evaluating the forest for fire conditions, it should be good enough to help check the accuracy of the equipment near by.

    best,

    Jack Barnes

I did not find any evidence in those two links supporting the assertion that GISS data is “not to be trusted.”

    My initial question to Anthony references that he wrote “For more information about why the GISS data isn’t much to be trusted” (emphasis added). That has me looking for something in the original blog entry which is his evidence. I repeat: what is the evidence in Anthony ‘s blog ?

  169. Robert says:

    This whole thing about the warmest year “ever” is so tiresome. How many times have you heard someone tell you the weather has never been so hot, never been so cold, never been so wet, etc? People have short memories and the data is not adequate to be able to really make these statements. And never mind the fact that it’s a “so what” kind of statement anyway. Yet the warmers continually pump this information out with menacing connotations. This is not neutral science, it’s agenda driven nonsense.

  170. josef says:

    The only source to be trusted it seems is the satellite record. So that has 2009 as the 7th warmest year, but only takes into account the past 30 years. The last 10 years shows no significant warming or cooling.

    @ josef (10:01:41) :

    “The only source to be trusted it seems is the satellite record.”

    Even if the satellite is correct, ( and I would have to add, correct compared to what? Is somebody checking the surface temps with a thermometer to see if they match up with the satellite?)

    From what I’ve read here, the satellite temps are measuring only the surface of the oceans and this is new data that was added 30 years ago. (And please, somebody correct me if I’m wrong,) I presume then, that they did not include ocean surface temps before that or that there were very few. If this is true then, how do you mesh the old data with a whole set of new data, (and oceans and land are like apples and oranges,) to come up with a global temperature that has any meaning compared to the simple land temperatures before?

  173. Pascvaks says:

    Was it the warmest year ever for you? Maybe yes? Maybe no? I guess how we answer depends on where we live. Is it “true” that it was the warmest year in modern times for the planet from an honest Scientific” data perspective. Who knows.

    The biggest problem that Hansen and NASA and the Met Office has (and so too many other Weather professionals as well) is that they have lost a lot of credibility with the people who pay their wages and buy their expensive little toys. Hansen tried to pull off a con, for whatever reason, and he failed. He used his office and connections to do it. He embarrassed NASA, his associates, and the politicians and business men who sought to use him for their own dubious reasons.

    When we think of rats leaving a sinking ship we often think of them jumping into the water near the waterline. There are, however, others who run to the highest parts of the vessel. Hansen will be found at the top of the topmast. He will be the last to drown.

    What of duty, honor, country? What of integrity? What of NASA or The Met? For many these never were, and never will be, matters that they ever gave the slightest thought. The worst fight you’ll ever have will be the one you have with a rat you’ve chased into a corner, or up to the topmast of a sinking ship.

    I’m sure their bosses are scared to death and don’t even want to think about handing them a pink slip.

    Tom in Florida (07:42:40) :

    A year or so ago, perhaps two, a poster asked if the communications transmissions we all use would have any effect on the air temperatures. Anthony showed how weak those transmissions were and thus had no effect. Is it time to revisit that as communications have increased exponentially or are they still too weak to play a part?

    Think about it Tom, this is actually a very effective way of getting rid of energy (via energy conversion to RF or ‘radio waves’).

    At least half of the EM energy from any given ‘transmission’ heads into space (assuming vertically oriented dipole, doughnut-shaped rad pattern etc) and a portion of the balance is reflected and makes its way into space too. Conversion efficiences of PAs (power amplifiers) overall of VHF – UHF range from 60% (good) to 30% (poor) so there is locally generated ‘heat’ that may outweigh effects of ‘heat’ directly due to the RF EM energy …

    And, the vast majority of the wavelengths/frequencies you’re concerned with here see an ‘optically transparent’ path/opening into space, regardless of overcast …

    It may have been the warmest decade in total, but the temperatures were still cooling over the entire decade. There is no warming trend in the 2000s, yet it is still the warmest. Guess it depends how you look at it, and it’s kind of misleading. As long as the rate of warming in the 1990s was greater than the 2000s, the 2000s will be a warmer decade. It’s a meaningless statistic.

  194. kadaka says:

    John Finn: You are missing something. US land temperatures follow water temps. We have long ocean coastlines, some of the contiguous states are practically surrounded. The Pacific and Atlantic oceans, the Gulf of Mexico… To the north are the Great Lakes and the Arctic Ocean. Don’t forget the cases of Hawaii and Alaska if looking at all the states.

    The water has the most abundant surface area. Whatever heat gets generated over the largest land masses, Europe/Asia, Africa, even South America, does not get to us without crossing that water which influences the received warmth.

    With our small 1.5% (or 2% as you state it) surface area, it is obvious that our temps should be controlled by the large bodies of water. Likewise, global temps should also see a controlling influence, simply because the water has by far the greatest surface area, its temps are the largest amounts in the global average.

    Yet do the US high temp record years match with the global ones? Nope. So, why not?

    What caused all that heating in the contiguous US during the 19xx years to push them higher than global? What caused cooling during the 200x years to give us lower than global?

  195. Bob Tisdale says:

    san quintin (04:09:09) : You wrote, “Interesting that a number of posters here find the recent warm 2009 hard to accept. Don’t they know that if you put a whole load of carbon dioxide into the atmosphere it will (in the absence of a negative forcing) have a warming effect? If they don’t know this then I suggest they go back to school. It’s high-school physics.”

    Unfortunately, what is taught in high-school physics misrepresents the actual effects of carbon dioxide. There is no indication that downward shortwave radiation from anthropogenic greenhouse gases has any impact in Ocean Heat Content. Refer to:
    http://bobtisdale.blogspot.com/2009/09/enso-dominates-nodc-ocean-heat-content.html
    The variability of the North Atlantic OHC has been explained as a product of the North Atlantic Oscillation and ENSO:
    http://bobtisdale.blogspot.com/2009/10/north-atlantic-ocean-heat-content-0-700.html
    And the North Pacific, similarly, appears to be driven by variations in atmospheric pressure:
    http://bobtisdale.blogspot.com/2009/12/north-pacific-ocean-heat-content-shift.html

    Lower troposphere temperature anomalies show upward step changes that result from strong El Nino events:
    http://bobtisdale.blogspot.com/2009/06/rss-msu-tlt-time-latitude-plots.html

    Sea surface temperature records show that approximately 25% of the global oceans can warm, counterintuitively, during La Nina events due to oceanic processes that redistribute warm waters back to the East Indian and West Pacific Oceans. The impacts are noticeable after strong El Nino events.
    http://bobtisdale.blogspot.com/2009/11/more-detail-on-multiyear-aftereffects_26.html
    And:
    http://bobtisdale.blogspot.com/2009/11/more-detail-on-multiyear-aftereffects_26.html

    So, in summary, the rise in global temperatures over the past 30 years can be explained as multiyear aftereffects of ENSO.

    Maybe we need to look at the state of measurements during that period (number of stations, locations, etc). Force them to explain why they can’t follow the recommendations of the WMO (i.e, use the latest decade for your averaging period).

    san quintin (04:50:26) :

    Baa Humbug
    No, I wasn’t being sarcastic. I’m just intrigued to see how many here thinks that dumping C02 quickly in the atmosphere will have little or no consequence.

    And I am totally astounded someone would actually think something as complex as the climate here on earth is completely dominated by a minor greenhouse gas especial given the geologic record of repeated Ice Ages. If CO2 was the main driving force weather forecasting would be very simple.

    This is the absorption spectrum of the greenhouse gases notice water is the dominant player. http://www.globalwarmingart.com/images/7/7c/Atmospheric_Transmission.png

    “There are about 30 times as many water vapor molecules in the air as CO2 molecules, and water vapor has a more effective fingerprint spectrum which is about three times wider than that of CO2. It is also much more variable. This means water vapor will swamp whatever CO2 does. It is obviously not being honest to say CO2 does twenty percent of the heating, when there is a hundred times as much effect by water vapor doing the same thing.” Also the IPCC report shows there is a major increase in water vapor due to man. Irrigation of deserts such as California, Arizona and the middle east. Watering of lawns and golf courses, irrigation of farmland….

    Mars is also warming according to the National Geographic so tell me what the earth and mars have in common that might explain BOTH warming at the same time? http://news.nationalgeographic.com/news/2007/02/070228-mars-warming.html

    You might want to read http://www.greenworldtrust.org.uk/Science/Curious.htm

    Then think about this:
    Everyone agrees about the Milankovitch theory of the cause of ice ages. And we are now seeing a change in the earth’s magnetic field, earthquakes, volcanoes erupting….
    Massive Volcanic Eruption + quiet sun + ocean cycles + Milankovitch cycle = ICE AGE and CO2 concentrations just does not matter.

    Lesson from the past: present insolation [energy from sun] minimum holds potential for glacial inception “. .we conclude that under natural boundary conditions the present insolation minimum holds the potential to terminate the Holocene interglacial.” [that means an ice age will start] “… early anthropogenic greenhouse gas emission prevented the inception of a glacial that would otherwise already have started.

    These predictions are based on continuously increasing anthropogenic greenhouse gas emissions and on the orbital forcing that will provide only muted insolation variations for the next 50 ka. To assess the potential climate development without human interference, we analyse climate proxy records from Europe and the North Atlantic of Marine Isotope Stage (MIS) 11 (423–362 ka BP), an interval when insolation variations show a strong linear correlation with those of the recent past and the future. This analysis suggests that the insolation minimum at 397 ka BP, which provides the best available analogue to the present insolation minimum, terminated interglacial conditions in Europe. At that time, tundra–steppe vegetation spread in Central Europe and pine forests dominated in the eastern Mediterranean region. Because the intensities of the 397 ka BP and present insolation minima are very similar, we conclude that under natural boundary conditions the present insolation minimum holds the potential to terminate the Holocene interglacial. Our findings support the Ruddiman hypothesis [Ruddiman, W., 2003. The Anthropogenic Greenhouse Era began thousands of years ago. Climate Change 61, 261–293], which proposes that early anthropogenic greenhouse gas emission prevented the inception of a glacial that would otherwise already have started.

    “SOLAR-PLANETARY-CLIMATE STRESS, EARTHQUAKES AND VOLCANISM”
    ABSTRACT

    The largest volcanic eruptions since AD 1800 correlate with periods of enhanced seismicity , changes in the earth’ s spin rate, and the Chandler wobble.Furthermore, a marked increase in the number of major eruptions apparently occurred during the Maunder Sunspot Minimum (1645-1715) at a time when global temperatures were depressed. Solar activity might trigger volcanism through solar-induced climate change which could lead to variations in global spin rate and hence to increased crustal stresses and seismic and volcanic potential . Such solar activity may be modulated by planetary tidal effects which might additionally lead to enhanced crustal stress through direct influence on the earth’s axial tilt, wobble and rate of rotation .
    A good correlation exists between the long-term smoothing of the sunspot cycle, and Greenland temperatures – with cool temperatures corresponding to long-term sunspot minima
    We acknowledge valuable discussion with R. W. Decker, J. E. Hansen [James Hansen] and J. E. Sanders. Work was supported by NASA.”

    If you ignore all the competing theories on the mechanisms driving earth’s climate and just look at what mother nature tells us in the geological record you can see we are on borrowed time and the slide int an major ice age takes only a decade. http://www.whoi.edu/page.do?pid=12455&tid=282&cid=10046

    On page 7 of David Archibald’s “Solar Cycle 24: Implications for the United States” he shows a plot of the last five Volstok interglacials superimposed and aligned on peak temperature vs time. http://westinstenv.org/wp-content/Solar_Arch_NY_Mar2_08.pdf

    A little ice age or even worst a major Ice age is a much worse nightmare the CO2 caused global warming AND it is absolutely guaranteed to happen the only question is how soon.

  200. Dave Wendt says:

    “The past year was a small fraction of a degree cooler than 2005, the warmest on record, putting 2009 in a virtual tie with a cluster of other years –1998, 2002, 2003, 2006, and 2007 — for the second warmest on record.”

    That sentence is forcing me to reevaluate my limitations as an ignorant nonscientist type. Foolish clod that I am, when I look at that statement, I’m tempted to suspect that for seven of the last twelve years global temps have been laying there like a dead dog. If you throw in the dramatically lower number for 2008, a dumbhead like me can delude himself into thinking he might be seeing signs of an actual decline in the trend.
    Lucky for me I’ve got a guy with the lively scientific intelligence of Mr. Hansen to point out how foolish I am to even consider such nonsense. Evidently, when looked at scientifically, a 12 year period where the temp at both ends, and most of the middle, is virtually identical and one year is dramatically lower actually indicates a dramatic rising trend. Who’d a thunk it? When I was young and my brain was more limber I might have been able to get my mind around such advanced scientific ideas, but my advancing years must be causing a certain mental rigidity to set in, because try as I might, I can’t do it nowadays.
    I guess I’ll go make some cocoa and sit in my rocking chair for a while.

    * 2000-2009 was 0.68 deg C cooler than 1881-1890

    * Statistically, the difference between the two groups, A and B, is significant at a confidence level of 99.98% (z = 3.73).

    Conclusions

    1. Heat-island effects are significant.

    2. Temperature records obtained in affected locations such as cities and airports must be excluded from estimates of national and global temperatures.

    * 3. In that case, the decade 2000-2009 in Australia was 0.68 deg C cooler than it was in 1881-1890.

    Estimates are derived from Mean Maximum Temperatures per favour

    for the following longstanding operational met stations:
    City/Airport: 38003, 61055, 66062, 80015, 86071, 94029
    Remote: 26026, 46043, 55023, 58012, 64008, 69018, 75031, 83025, 84016, 85096, 90015

    Records at these stations are reliable according to this statement by NASA in the current WUWT article: “Looking back to 1880, when modern scientific instrumentation became available to monitor temperatures precisely….”

    Slightly OT but a clear indication of biased presentation of temperature informatio, whilst browsing I discovered this on NASA Earthobservatory site:
    http://earthobservatory.nasa.gov/IOTD/view.php?id=36900

    It shows Australia and has the caption “Exceptional Australian Heatwave”. Now when I look at the image I see that the southern part of Australia is indeed suffering from high temperatures, but it also shows the north suffering(if that is the word to use) from equally anomalous low temperatures, and to my eye I judge that the low temperature areas are slightly more extensive than the high.

    So temperatures averaged across Aus as a whole (on the same basis as global averages are arrived at) are probably about normal or even a little on the cool side.

    The big difference is that most of Australia’s inhabitants live in the hot, bit so whinge about it, blog about it and the media covers it

    What part of that don’t you get? Does your PC not show links for some reason? Or are you being a troll for the sake of it?

    I get it all, except for when you write “For more information about why the GISS data isn’t much to be trusted … .” My dictionary defines “more” as “in greater quantity” or “additional.” There’s nothing preceeding that sentence you have classified as “information about why the GISS data isn’t much to be trusted.” All I’ve asked is for you to point me to the non-additional evidence for your assertion. I have been clear about this since my post at 06:15:22.

    Other websites do a very good effort at posting hyperlinks or listing reference documents that support their assertions along the way. You wrote your post (“for more information”) in such a way that I have to take it on faith that there’s information out there supporting your assertion. I won’t. I expect you to back it up with solid evidence.

    REPLY: Well you are the only one who’s complaining about the word formatting, and I find your argument petty. Read the links that you’ve been ignoring “since my post at 06:15:22″. That’s where the “more” information is. When people make valid complaints about formatting or other issues here, I correct them, so far your single complaint hasn’t risen to a level of credibility that make it worth correcting, mostly it is that of what’s called a “concern troll”. Stop wasting my time with Clintonian arguments on a single word – A

    “…why the GISS data isn’t much to be trusted…”

    All of the GISS data manipulations seem to result in more steeply rising temperatures. For example, here’s a blink gif showing Hansen’s “adjustments” of the temperature record: click

    GISS lacks credibility. I have more links if you’re interested.

    Of course it is was a warm decade, if you can massage the figures to say so. This is the Central England temperature record – largely raw data:

    http://www.climate4you.com/CentralEnglandTemperatureSince1659.htm

    This is the same temperature set after Hadcrut got hold of it:

    http://artofteachingscience.org/images/mean_england_temp.gif

    The second graph is a graph of the anomalies. This is the more useful graph because it presents the data on a scale which shows the variation more clearly. The first set of graphs can be misleading. For example the temperature scale includes several values which are irrelevant for most of the seasons (e.g. summer has never had values between 0 and 10). You might just as well use the Kelvin scale and a use values between 0 and 300 degrees.

    Gail Combs (15:38:45) :
    sAnd I am totally astounded someone would actually think something as complex as the climate here on earth is completely dominated by a minor greenhouse gas especial given the geologic record of repeated Ice Ages. If CO2 was the main driving force weather forecasting would be very simple.

    This is the absorption spectrum of the greenhouse gases notice water is the dominant player. http://www.globalwarmingart.com/images/7/7c/Atmospheric_Transmissi

    Sorry Gail but that ‘spectrum’ of the outgoing radiation is little more than a cartoon and is totally useless for any understanding of what’s going on. I’ll post something more realistic later.

  212. Wondering Aloud says:

    Does the known cherry picking of and ignoring low temperatures in Siberia have anything to do with this? How about the dropping of high latitude and high altitude sites in Canada?

  213. Wondering Aloud says:

    Actually John Finn the second graph “clearly shows” that the Had/CRU ia fudging the data. Man made global warming indeed!

    Here it is, the first image is the outgoing longwave through the tropical atmosphere at 70km, the absorbing gases removed progressively as shown on the figure.

    the article best describes the future effect of temperature on earth. if this temperature continues then the end of world begins

    I will — when you admit that your post contains no evidence about “why the GISS data isn’t much to be trusted”

    ;)

    I know this dispute, but then please tell me, why the standard reference period used in climatology lasts from 1961 to 1990 (1971 – 2000) and not from 1960 to 1989?

    Anyway, it is just a random chosen period of time, no matter where it starts and ends…
