While there’s been a lot of attention given to the recent NOAA and NASA press releases stating that 2010 was tied for the warmest year globally, it didn’t meet that criteria in the USA by a significant margin according the the data directly available to the public from the NOAA National Climatic Data Center. (NCDC)
Here’s the graph of USA mean annual temperature from 1895-2010 produced by NCDC’s interactive climate database and graph generator, which you can operate yourself here: http://www.ncdc.noaa.gov/oa/climate/research/cag3/na.html
Note the rank highlighted in yellow. The pulldown menu gives you an idea of what was the warmest year in the USA from this data, arrows added:
Here’s the partial table output (you can use their online selector to output your own table) sorted by rank from NCDC web page. 1998 leads, followed by 2006, and then 1934. 2010 is quite a ways down, ranking 94th out of 116.

*Highest temperature rank denotes the hottest year for the period.
Lowest temperature rank denotes the coldest year for the period.
Data used to calculate Contiguous United States mean temperatures are from the USHCN version 2 data set.
Of course there is no mention of the USA temperature ranking in the recent press release from NOAA. The only mention of the USA in that PR that comes close is this:
In the contiguous United States, 2010 was the 14th consecutive year with an annual temperature above the long-term average. Since 1895, the temperature across the nation has increased at an average rate of approximately 0.12 F per decade.
There’s no mention of the 2010 ranking for the USA temperature at all, nor any mention of the fact that 2010 was not nearly as warm as 1998, or 1934. I find that more than a little odd for an agency whose mission is to serve the American people with accurate and representative climate data.
They couldn’t find room for a sentence or two to mention the USA historical temperature rank for 2010? Apparently not.

Temperatures are increasing at a rate of about 0.2 degrees C per decade. That’s not flatlining. However, you cannot reliably measure a trend over just one decade, that’s too short a time span. It only becomes statistically significant when taken over several decades.

I am the farthest thing from being an AGW proponent, but I’m 100% sure the NCDC’s “hottest year” designation for 2010 was for the entire planet, not the US. This is kind of a red herring.
Not really, imo, because it re-emphasizes, by using the still not well known U.S. vs World temperature record disjunction, the fact that what the ipcc style Climate Science does not tell us continues to reflect the same way on what it does tell us.
As I recall it, back when the fact of the failure of the U.S. to conform to Climate Sciences’s AGW was demonstrated about 4-5 yrs.[?] ago by Steve McIntyre on Climate Audit, the warmists immediately started saying it didn’t matter, since the U.S. was “only about 2%” of the Earth’s surface, and that was all there was to it! They didn’t even mention that the U.S. comprises about 6% of the Earth’s land surface, which McIntyre’s blog instead quickly noted as part of its consideration of the disparity between the records.
In other words, back then, the warmist scientists already seemed way too unscientifically interested in vigorously ignoring the possible greater problem that the U.S. temp. figures showed everyone else once Steve M. displayed them to the world: that the rest of the world’s [ROW] figures might in fact show the same kind of thing, once people start actually looking at them independently – for example, such as the CET record does show, which I think Tonyb was very instrumental in bringing to everyone’s attention here at WUWT; the second problem Steve’s work possibly implied was that the U.S. should have much more reliable records on average than the ROW.
These considerations could certainly raise a valid question within any objective person as to whether we can we really trust Climate Science’s whole GMT.
By now, imo, knowing even more about how ipcc style Climate Science does its “science” – it’s not – the validity of what the NCDC says is much more in doubt than it was back then. I don’t believe hardly anything official Climate Science says anymore, and certainly not its always hockeysticking “hottest year ever” claims.
And I actually hope the “world” is in fact warming! Whereas, even more bizarrely, ipcc Climate Science desperately wants us to commit suicide, if it is warming, “before it’s too late”!

If it’s not an enhanced greeenhouse effect, what physical process do you think is driving the current warming?
Anybody can easily tell it was all a lie… The earth has been cooling for 12 years … Just plot a trend line over temp records since 1998.. Then tell me the earth is getting warmer…the slope obviously declines…. Its all government manipulation I yell ya..
Roger Otip: “For the past three decades temperatures have been increasing.”
It increased just as much from 1910 to 1940 … possibly more depending on manipulation/UHI. Yet CO2 is not considered factor in the 1910 to 1940 warming.
Why not?
If the world is not warming much in North America and Europe then how can we get a better understanding of the accuracy of measurements showing warming in Canada and the Antarctic?
“While there’s been a lot of attention given to the recent NOAA and NASA press releases stating that 2010 was tied for the warmest year globally, it didn’t meet that criteria in the USA …”
Nationalism run a muck.
Anthony, exactly.
And I can report that in my refrigerator, temperatures have in fact FALLEN dramatically since I installed it. I’d further note that at every moment during its use I’ve been using greenhouse gas-emitting natural gas to generate the electricity to power it.
Take that, Hansen.

@kdkd January 14, 2011 at 3:50 am:
Let’s see, the US was the 13th warmest, while South America had about its coldest winter ever, Australia had one of its coldest winters AND summers, Europe had a very cool summer and a horrible blizzard-filled winter. And the SSTs were not at record levels, but dropping for the last 1/3 of the year, due to the oncoming La Niña.
It SNOWED in Australia the day before their summer solstice, and not just in one place. No place in Australia that day averaged over 40°F – not even Darwin. Where was the snow? Some was almost exactly on the Tropic of Capricorn – the SH equivalent of Havana, Cuba. Can anyone here believe that if it snowed in Havana (or Miami) on June 20th that people wouldn’t be asking WTF about “hottest year” bullcrap? If it snows in Miami on DEC20th, it would be huge news, much less the day before official summer. (Yes, and now, kdkd, you will pull out the “weather isn’t climate” pap, as is done when it suits your purposes. . . )
With all those places weighing in on the not hottest side of the ledger, just WHERE did all the heat come from? These are places mostly with the best coverage anywhere. There must have been SOME huge areas that had record highs. Where were they? And when you find them, then go look for how many places had record lows. THEN tell us they aren’t cooking the books.
Some records were set in Russia and Pakistan – one period of a few weeks of big-time heat – and those are the only non-adjusted data out there that argue for 2010 being so hot. Frankly, I think the fudging is so rampant they think they can just keep adjusting and adjusting and everyone will buy it forever. When the UHI adjustments are done properly, all those climatologists are going to look like the biggest idiots on the planet – and no one will trust them with their data ever again.
No mention of 2010 ranking for US temperature at all? How about in the first paragraph of the press release?
Quote: “According to NOAA scientists, 2010 tied with 2005 as the warmest year of the global surface temperature record, beginning in 1880. This was the 34th consecutive year with global temperatures above the 20th century average. For the contiguous United States alone, the 2010 average annual temperature was above normal, resulting in the 23rd warmest year on record.”
Note that last sentence. “23rd warmest” seems to imply some sort of ranking system to me. Plenty of room there for 1998, 1934, and whatever else you want to throw in there.

Roger, please answer me why there has been no warming in Philadelphia PA since 1874. Is it because CO2 avoids the city of brotherly love? If you can give me a rational answer as to how the globe can warm up due to CO2 but avoid Philly then I will believe the AGW meme.
Roger Otip: “Temperatures are increasing at a rate of about 0.2 degrees C per decade. ”
1911 to 1944: an increase of .673C = .22C per decade.
1944 to 1989: an increase of .009C = 0.0C per decade.
Which of the above was caused by rising CO2?

For those carping about noting that the US wasn’t particularly warm, of course it makes a difference. It’s supposed to be global warming, right? Well, clearly it isn’t global as the US and many other major populated areas were not warm. ”

Sorry but you completely misunderstand and misrepresent the issue. Climate change is about the effects on the planet as a whole. This does not mean that the warming is the same at every point on the globe, some parts will be hotter, colder, drier, wetter, calmer, stormier etc etc. This is called weather and as climate change increases will get more extreme and more unpredictable. The issue is that on a global scale the long term warming will shift and change the climate in ways that will be damaging for our way of life.
It is a simplistic and unrealistic view of the issue to assume that the planet is so uniform and predictable that it is say 0.16 degree warmer everywhere at the same time.

Since the upper and lower confidence limits of my fits contain zero, it means there is no statistical confidence for any slope. I am not claiming a positive or negative slope. The stats suggest zero slope. And if you believe there is a measurable slope, it’s on the order of 6e-6 meaning Philly will increase 6 degrees in 1 million years!
While I’m just beginning to understand the what I’m reading here at WUWT about how greenhouse gases are supposed to work, it seems to me that the US should be warmer than the rest of world, not colder.
My understanding is that CO2 reflects some of the long wave radiation from the surface back to the surface, making the surface warmer than it would be otherwise. It is also my understanding that this is a continuous process.
Also, the US is second, behind China, in the emission of CO2 into the atmosphere. Since it takes a finite time and distance for the CO2 to difuse, it stands to reason that CO2 should be higher over the US (although I have not seen CO2 readings for US) than over the ocean or other areas with lower CO2 emissions.
Since CO2 is higher over the US the greenhouse effect should be more pronounced over the US, and the average yearly US temperature should be higher than the global average temperature. Wonder why it is not.
Someone asked about where the hot spots were in 2010.
The NOAA (the group claiming 2010 as tied for warmest on record) has a picture (link below) which shows their data for the parts of the planet that were either colder or warmer than average in 2010. These data show that the Eastern Pacific was colder than normal which I believe is expected during a La Nina event (we’re in one now). It looks like Greenland and parts of Eastern Canada win the “hotter-than-normal” award.

“Can it possibly be true that no one here recalls that tens of thousands of people died in Russia due to the raging fires and record smashing heat wave? In addition, the Arctic saw 5 degree C anomalies for the year. The global number is correct. Don’t think that these anomalies will go away or never affect the U.S.”
Yes, the heat wave in western Russia lasted how long – 3 weeks? And the Arctic temperatures are modeled by DHI:
http://ocean.dmi.dk/arctic/plots/meanTarchive/meanT_2010.png
As you can see, the Arctic was below average between day 140 and day 240 in 2010. The rest of the year was mostly above average, but nothing at all like the 5K you claim. Annual average according to DMI seems to be more in the order of 0.5-1K, ie about 1/5 to 1/10 of your claim.
Where do you get your information from Erik, do you just make it up as you go along? And based on this nonsense you conclude that “The global number is correct.” ?
Please substantiate your claim that “the Arctic saw 5 degree C anomalies” for the year (2010).
I still believe that these comparisons of warmer or cooler years are not meaningful because of false precision. There is no confidence in tenths or hundredths of a degree F when the foundational data is in whole degrees.
For an extensive discussion of False Precision in climate figures, see this post from E.M. Smith: http://chiefio.wordpress.com/2009/03/05/mr-mcguire-would-not-approve/
RE: Ron C., January 15, 2011 at 8:52 am
The tenths and hundredths can be meaningful, but only if the error interval is included in the analysis. NOAA has started making this more of a habit in their monthly climate reports, but GISS has not done so to my knowledge. If GISS started making this standard practice, I would put higher stock in their numbers because then we could have a better sense of how much fudging and estimating really IS going on in their analysis.

Also, since 2010 was one of the warmest globally (in the top 3 if not the warmest), even though it was cold in the USA, that means there must have been parts of the world where 2010 was unambiguously the warmest – anyone know which bits?

Probably the parts that are 250km or more from a thermometer.”
For a good laugh, the posters here never disappoint!
While EMS’ writeup is correct in general, there are a few minor errors and some other clarifications he should have added. The “Dominic” he debates is wrong for reasons beyond (in addition to) what EMS cites, too. He closed off comments so I cannot add these points.

I don’t mean to pick on you Michael but this idea seems odd. On the one hand we are to ignore a cold area because Global Warming is well, Global. But on the other hand the globe is not homogenous so it must be treated as parts (when it’s convenient.)
Too often I see people trying to have their cake and eat it too. You can’t explain the hypothesis’s failure on a major land mass by claiming the hypothesis is only applicable at a larger scale. Then turn around and say that the effects at that scale don’t exist, they only exist at smaller scales. Forgive me if that was not your intent.
If global warming due to CO2 only affects some areas, but these areas have the same concentrations of CO2 as everywhere else, something is amok in this theory.

Quote: “If global warming due to CO2 only affects some areas, but these areas have the same concentrations of CO2 as everywhere else, something is amok in this theory.”
I don’t think the theory says that CO2 only affects some areas and not others. To my understanding, it says that the effect will be global, but affect different regions in different ways at different times.
Suppose the effect of warmer oceans and a warmer atmosphere was to change the position and amplitude of the jet stream. That would cause some places to be warmer than they were before and some to be cooler simply because the jet stream shifted positions. Similarly, it doesn’t guarantee that the same location will feel the same effect throughout the year. A change in ocean or atmospheric patterns may cause one location to be cooler during the summer but warmer during the winter. It’s this premise which keeps the claim that AGW will cause more droughts and more flooding from being complete nonsense.
I may be wrong, but that’s my understanding of things.
BillyBob
CO2 is considered to be a factor in the early 20th century warming, but probably not the primary factor which is thought to be an increase in solar irradiance during that period. The differences between that period of warming and the warming over the last three decades are a) greenhouse gas emissions are much higher now, and b) solar irradiance has not been increasing.
