NASA – 2017 was 2nd warmest year, NOAA says 3rd warmest, El Niño a major warming influence

From NASA Goddard:

Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.

Continuing the planet’s long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. That is second only to global temperatures in 2016.

Video: Earth’s surface temperatures in 2017 were the second warmest since since 1880, when global estimates first become feasible, NASA scientists found. Global temperatures 2017 were second only to 2016, which still holds the record for the hottest year; however, 2017 was the warmest year on record that did not start with an El Nino weather pattern, as the previous two years did. In a separate, independent analysis, NOAA scientists found that 2017 was the third-warmest year in their record. The minor difference is due to different methods to analyze global temperatures used by the two agencies, although over the long-term the records remain in strong agreement.

In a separate, independent analysis, scientists at the National Oceanic and Atmospheric Administration (NOAA) concluded that 2017 was the third-warmest year in their record. The minor difference in rankings is due to the different methods used by the two agencies to analyze global temperatures, although over the long-term the agencies’ records remain in strong agreement. Both analyses show that the five warmest years on record all have taken place since 2010.

Because weather station locations and measurement practices change over time, there are uncertainties in the interpretation of specific year-to-year global mean temperature differences. Taking this into account, NASA estimates that 2017’s global mean change is accurate to within 0.1 degree Fahrenheit, with a 95 percent certainty level.

“Despite colder than average temperatures in any one part of the world, temperatures over the planet as a whole continue the rapid warming trend we’ve seen over the last 40 years,” said GISS Director Gavin Schmidt.

The planet’s average surface temperature has risen about 2 degrees Fahrenheit (a little more than 1 degree Celsius) during the last century or so, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Last year was the third consecutive year in which global temperatures were more than 1.8 degrees Fahrenheit (1 degree Celsius) above late nineteenth-century levels.

Phenomena such as El Niño or La Niña, which warm or cool the upper tropical Pacific Ocean and cause corresponding variations in global wind and weather patterns, contribute to short-term variations in global average temperature. A warming El Niño event was in effect for most of 2015 and the first third of 2016. Even without an El Niño event – and with a La Niña starting in the later months of 2017 – last year’s temperatures ranked between 2015 and 2016 in NASA’s records.

In an analysis where the effects of the recent El Niño and La Niña patterns were statistically removed from the record, 2017 would have been the warmest year on record.

Weather dynamics often affect regional temperatures, so not every region on Earth experienced similar amounts of warming. NOAA found the 2017 annual mean temperature for the contiguous 48 United States was the third warmest on record.

Warming trends are strongest in the Arctic regions, where 2017 saw the continued loss of sea ice.

NASA’s temperature analyses incorporate surface temperature measurements from 6,300 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.

These raw measurements are analyzed using an algorithm that considers the varied spacing of temperature stations around the globe and urban heating effects that could skew the conclusions. These calculations produce the global average temperature deviations from the baseline period of 1951 to 1980.

NOAA scientists used much of the same raw temperature data, but with a different baseline period, and different methods to analyze Earth’s polar regions and global temperatures.

    • Sid, the video says that the co2 is made in to three sludges — calcium carbonate — the thickest — on top, bio-fuel — thinner — in the middle and bio-fertilizer — the thinnest — on the bottom. Please explain:

      a. how thicker (i.e. heavier) sludges float on the top.

      b. how use of bio-fuel use will not result in co2 exhaust

      c. how calcium carbonate (used in cements) will not outgas co2

      d. how bio-fertilizer places on soil and exposed to the sun will not outgas co2

      • So spray an amine on CO2 and it reacts with it. So what? This is hardy worthy of a patent.

        Better to add hydrogen to CO2 and make hydrocarbons. They can be made at a lower price than conventional methods eg CSG, drilling etc. Then capture the CO2 from that process and do it again. The power can be sourced from off grid solar and wind or on-grid coal at off peak times.

        All this works, it simple to make and is proven. It needs NO government subsidy other than a credit for the transformed carbon. This credit would be passed down the supply chain. It involves no money unless the CO2 is not reused. Its easily measured. At that point its up to each state. Some will charge for the CO2, others not charge. This is a political decision.

    • In spite of NOAA’s propaganda film; they have yet to prove CO2 effects on temperature are measurable.

      NOAA is unable to demonstrate this warming period is, in any way, remarkable and different from previous warming trends.

      N.B. NOAA’s claim regarding temperatures since 1880.
      • a) Tell us all about how temperatures were measured in most parts of Africa, portions of Australia, S.E. Asia, Mojave desert, Black Rock desert, Mongolia, and at both polar regions?
      • – i) It wasn’t!
      • – Comparing today’s temperatures to most of the past is not a legitimate comparison. Forget apple compared to oranges! NOAA’s fake comparison is akin to comparing mollusks to hominoids.

      • b) Even today, after NOAA removed thousands of uncooperative inconvenient thermometers from NOAA’s temperature measurement network; especially those cooler reading thermometers at higher latitudes, higher altitudes and obstinately cooler rural sites.
      • – i) NOAA installed a modern temperature network… almost. A large majority of temperature sensors are located at urban airports. All of that tarmac and jet engines is so helpful when recording temperatures unaffected by urban environments… Not!

      • c) Then there is NOAA’s temperature smudging, where NOAA smears a preferred thermometer reading as if that temperature is identical up to 1200km away. NOAA, also performs that task for other global sites lacking thermometers.

      • d) 1880 is a period that was warming since the LIA ended. Today, that warming continues from the LIA!
      • – i) It’s called cherry picking! NOAA happily ignores temperature reconstructions for earlier warmer periods during the Holocene; just so NOAA can support CAGW; or actually, the political movement dependent upon CAGW.
      • – ii) Even with recognizing that 2017 is during a warming period following the LIA;
      • – NOAA is unable to claim “warmest”, “2nd or 3rd warmest” without NOAA “adjusting” past and current temperatures.
      • – NOAA, ignores their own temperature sensor network issues! NOAA does not measure, track or record error rates intrinsic to their temperature recording process. If proper error bars were tracked and displayed, it is unlikely that NOAA’s alleged temperature records could be stated within several degrees accuracy.

      The difference between 1880’s alleged CO2 portion of the atmosphere, e.g. 280ppm; and today’s CO2 atmospheric portion, i.e. 400ppm works out to 1.2 molecules per ten thousand atmospheric molecules.

      Yet, alarmists are panicking? Whatever for?
      Water vapor is massively more abundant in the atmosphere and is infrared active over a far larger portion of infrared frequencies. Water vapor is equivalent to a whale in the atmosphere compared to a tiny CO2 mouse.

  1. I have a great carbon capture technology…

    I call it ACO2RN.

    Autonomous CO2 Recovery Nodule.

    You just put them in the ground, and voila! Captured carbon.

  2. On a generous day, you could assume that we know what the Earth’s temperature was back in 1880 to within 5C.

  3. Did you notice the blue spot between Europe and Canada ?

    https://www.nature.com/articles/ncomms14375

    Observations over the 20th century evidence no long-term warming in the subpolar North Atlantic (SPG). This region even experienced a rapid cooling around 1970, raising a debate over its potential reoccurrence. Here we assess the risk of future abrupt SPG cooling in 40 climate models from the fifth Coupled Model Intercomparison Project (CMIP5). Contrary to the long-term SPG warming trend evidenced by most of the models, 17.5% of the models (7/40) project a rapid SPG cooling, consistent with a collapse of the local deep-ocean convection. Uncertainty in projections is associated with the models’ varying capability in simulating the present-day SPG stratification, whose realistic reproduction appears a necessary condition for the onset of a convection collapse. This event occurs in 45.5% of the 11 models best able to simulate the observed SPG stratification. Thus, due to systematic model biases, the CMIP5 ensemble as a whole underestimates the chance of future abrupt SPG cooling, entailing crucial implications for observation and adaptation policy.

  4. Wait “warmer than the 1951 to 1980 mean” thats the period they use for the mean? Why that period?

  5. Why are there two different taxpayer-supported agencies playing the same statistical games, and making the same meaningless conclusions. I thought NASA was supposed to be returning to advanced aeronautics, and space research!

  6. and with a La Niña starting in the later months of 2017

    La Niña has not started yet. La Niña conditions are present, but it requires several months of La Niña conditions and certain other conditions to declare a La Niña event. They don’t appear to know what they talk about.

    In an analysis where the effects of the recent El Niño and La Niña patterns were statistically removed from the record, 2017 would have been the warmest year on record.

    This is bullshit. There is no way to remove the effect of Pacific SST on the rest of the climate system, and the time it takes the extra heat from an El Niño to go through the system is variable and not well known.

    Warming trends are strongest in the Arctic regions, where 2017 saw the continued loss of sea ice.

    Directly a lie. Summer Arctic sea ice did not decline in 2017.

    NASA Goddard produces such low quality reports and science that should be disbanded.

    • Javier,
      “They don’t appear to know what they talk about.”
      Here, dated November 8 2017, is a report from NOAA headed
      “La Nina moves in for the winter”
      Here is BoM, 16 Jan 2018
      “Weak La Niña continues over the Pacific”

      “Directly a lie. Summer Arctic sea ice did not decline in 2017.”
      They did not say that summer ice declined (in extent). They said there was continued loss of ice. From WUWT’s sea ice page, we have:

      • Nick, Arctic sea is WELL above that of the MWP, and in fact, still in the top 10% of the last 10,000 years.

        What we see here is a RECOVERY from the EXTREME extent of the late 1970s, that was up there with the LIA extents.

        Thing is Nick, I suspect you KNOW all this full well.

        Either that, or you remaining wilfully blindfolded to the facts.

        Why continue to be so disingenuous, in your vain attempts to prop up the AGW FARCE?

      • Nick

        I’m sure that even you know that there is a lag of 3 to 6 months between the onset of El Ninos and La Ninas , and an effect on atmospheric temperatures.

        So why are you trying to mislead people?

      • “What we see here is a RECOVERY”
        What you see there is a typically doctored graph from one of Kenneth Richard’s lists. It is not in Stein’s paper, which I am sure you have never read. What he has done is to extract and rearrange a panel from a plot of a single sediment core, ARA2B-1A, in the Chukchi Sea. The heading “Holocene Cover Sea-Ice Variations” is added by Richards, it is not in the original. It is measuring a composite biomarker PIP2.5. They have about one data point per century, and the last shown is at 0 bp (very approximately. As always, 0 BP is 1950 ad.

        What Stein et al do say is that
        In the last four decades, the extent and thickness of Arctic seaice has decreased dramatically (e.g. Johannessen et al., 2004;Serreze et al., 2007; Stroeve et al., 2007; Cavalieri andParkinson, 2012; Laxon et al., 2013; Lindsay and Schweiger,2015), and this decrease seems to be by far more rapid thanpredicted by any climate model (Stroeve et al., 2007, 2012).The Chukchi Sea has become completely ice-free during thesummer of the last few years (Figs 2 and 3).”,/I>

      • “So why are you trying to mislead people?”
        No, you are misleading. GISS simply said that a La Nina was starting in the later months of 2017. Javier said “They don’t appear to know what they talk about.”. I simply pointed out that what GISS said was true. You may have theories on when temperature effects may be expected, but that doesn’t change the truth of what GISS actually said.

        “instead of ice area, which show September extent increasing since 2007?”
        Because I am dealing with what GISS actially said, which was “2017 saw the continued loss of sea ice”. They were not talking about September extent. Javier said that was a lie, but the sea ice volume graph (on the WUWT site) clearly shows that in fact, “2017 saw the continued loss of sea ice”.

      • RE Nick:

        ***“Directly a lie. Summer Arctic sea ice did not decline in 2017.”
        They did not say that summer ice declined (in extent). They said there was continued loss of ice. From WUWT’s sea ice page, we have:***

        So, Nick, show us the “continued loss of ice” between 2012 and 2017>
        Please…..

      • “So, Nick, show us the “continued loss of ice” between 2012 and 2017”
        Why do you keep trying to twist their simple statement into something they didn’t say at all. They said nothing about 2012. They just said the loss of ice continued in 2017, And it did.

      • La Niña: A phenomenon in the equatorial Pacific Ocean characterized by a negative sea surface temperature departure from normal (for the 1971-2000 base period) in the Niño 3.4 region greater than or equal in magnitude to 0.5 degrees C (0.9 degrees Fahrenheit), averaged over three consecutive months.
        (NOAA News Online, Feb. 23, 2005)

        There is loss of ice every year between March and September. There is no loss September 2016 to September 2017.

      • Niño 3.4 has not been <-0.5° anomaly for three months yet, so no Niña yet unless they break their own rules. And so no Niña in 2017.

        Ice volume is a modeled fiction. Pushed forward once extent stopped declining.

      • i>”La Niña”
        Let’s review. GISS said “and with a La Niña starting in the later months of 2017”. You said
        “They don’t appear to know what they talk about.”
        NOAA said in it’s December summary (for November)
        “La Niña strengthened during the past month, as indicated by an increasingly prominent pattern
        of below-average sea surface temperatures (SSTs) across the central and eastern equatorial Pacific Ocean
        (Fig. 1).”

        It seems GISS do know what they are talking about.

        “There is no loss September 2016 to September 2017.”
        I showed the sea ice volume anomaly plot. It deducts seasonal variations, and shows a clear loss of ice between Sept 2016 to Sept 2017.

      • “Nick Stokes January 19, 2018 at 1:20 pm
        “Directly a lie. Summer Arctic sea ice did not decline in 2017.”

        They did not say that summer ice declined (in extent). They said there was continued loss of ice. From WUWT’s sea ice page, we have:”

        Dealing from the bottom of the deck, Nick?

        That chart you show, ends just after 2017 begins. Virtually nothing of ice extent is shown for 2017.

        Nor does your chart show new lows. Instead, what is shown is a classic bottom bounce chart as the trend reverses.

        Add in that the chart begins at peak Arctic ice cycle conditions; makes it curious that alarmists and doomsayers are so unwilling to wait for several well documented sinusoidal cycles, before crying wolf.

        With a little luck, Earth will not drop back into Ice Age conditions; and we warmth loving creatures can thrive under warm conditions for a long Optimum.

    • “Warming trends are strongest in the Arctic regions,”

      Let’s look at UAH NoPol this century.

      As always, the ONLY warming was from the NA Blob and the El Nino.

      Quickly subsiding.

    • “It is not in Stein’s paper,”

      YES IT IS, just in a different orientation

      All that was done iwas to rotate, re-scale a bit and add the MWP and LIA and 20th annotation

      STOP LYING, Nick.

      Further backed by this graph.

      I know that DENYING science is your only option now, but just STOP IT !!

      • “STOP LYING, Nick.”
        The graph you showed is a lie. There is no indication, eithet by you or Richards, that “All that was done iwas to rotate, re-scale a bit and add the MWP and LIA and 20th annotation”. Let alone adding a false heading. And then it is all presented (by you) as “Arctic sea is WELL above that of the MWP”, instead of being just a single sediment core in a peripheral area, which has no data in the period of interest.

        And you are still presenting an altered graph. The actual original was:

        So you and Richards strip out the heading identifying it as core ARA2B-1A, strip the caption which its identifying information, put in fake annotations and headings, and present it as a graph of Arctic sea ice history.

        And it isn’t backed up by a graph in another location near Iceland. For one thing, that does show a big dip towards 1950. It also has approx century resolution and says nothing about recent decades.

      • “STOP LYING, Nick.
        Further backed by this graph.”

        Another fake from Richard’s notrickszone list of 485 papers. It’s hard to even see what he has done here. The has taken a composite of graphs related to a sediment core MD99-2269 from a site N of Iceland. Again he has rubbed out the adjacent information, caption, and a genuine annotation. Fake annotations have been added, the x-axis transplanted, a fake heading. And he has turned it upside down. Here is the original:

        You choose remarkably dishonest material to support your tedious charges of LYING.

      • ROFLMAO

        And there it is on the right of your first chart. for EVERYONE to see

        Are you WILFULLY BLIND !!!

        LYING even to yourself

      • Purple line in your second graph.. Exactly the same.. There for ALL to see.

        So hilarious at your attempts to LIE, then provide basically the same graphs they you say weren’t there.

        Let’s add some more.

        Keep proving me correct Nick, I thank you. :-)

      • If you don’t understand that rotating and adding some notes pointing to very obvious time periods…

        DOES NOT CHANGE THE DATA OF THE GRAPH AT ALL,

        Then more FOOL you, Nick.

      • “Let’s add some more.”
        More fοrgeries. At least we’re getting a good look at just how “notrickszone” and Kenneth Richard compile their lists of papers that cast doubt on global warming.

        Here is the orgoinal Yamamoto graph:

        Again, just one part ripped out and fake headings, annotations and axes added. The fake heading says “Holocene Arctic Sea Ice changes” but the original plot doesn’t say that. PIiP25 is not a unit of sea ice. But the joke here comes if you actually read the caption:

        It isn’t Yamamoto’s result. It’s just Stein’s results for that same single sediment core, ARA2B-1A, in the Chukchi Sea.

        And Kolling? well, here’s the original plot

        Once again, a fake heading and annotation has been added to an extracted portion which have no foundation in the original graph, which doesn’t identify any of the things plotted with sea ice. At least it’s higher resolution, but again Kolling doesn’t claim any results beyond about 1950.

      • It’s so incredibly amusing observing Stokes – someone who actually understands the science under discussion, and how those of a certain ilk distort and torture the science for purpose – dismantle and absolutely own the likes of AndyG55 … yet Andy, and a few others, soldier-on with full attitude seemingly oblivious to their being revealed for what they are … Hahaaa!

    • It seems GISS do know what they are talking about.

      No they don’t. As per NOAA, la Niña requires 3 consecutive months of below -0.5° C at Niño 3.4 region, a condition that is yet to be met. Probably next month they’ll issue an statement declaring La Niña. Talking about La Niña in 2017 is premature. As usual they bend their own rules to push forward a narrative.

      I showed the sea ice volume anomaly plot. It deducts seasonal variations, and shows a clear loss of ice between Sept 2016 to Sept 2017.

      As far as we know that loss has only taken place in some computers, not in the Arctic.

  7. They have no precise idea what global average temperatures were in 1880, 1940 or 1950 for that matter. How did they infill artic temps for 1880 or 1940?

    • USCRN seems to respond slightly more to El Nino type events than the satellite data does. (sd-dev 1.12 for USCRN, against about 0.74 and 0.88 for UAH and RSS)

      Before the 2015-2017 transient warm event, USCRN was basically a zero trend match with RSS ContUSA and UAH6 USA48

      At the moment, USCRN runs slightly higher than the other two, and they all have a slightly +ve trend due to the 2015-2017 El Nino.

      ClimDiv for USA is adjusted/calculated to be very similar to USCRN.

  8. I love how NASA excluded El Nino years in order to get the headline “2017 Hottest Year Evah!”

    Well, excluding everyone taller than me, I am the tallest man in the room.

      And where did they say that?

      They said…

      https://www.giss.nasa.gov/research/news/20180118/

      “Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.”

      “A warming El Niño event was in effect for most of 2015 and the first third of 2016. Even without an El Niño event — and with a La Niña starting in the later months of 2017 — last year’s temperatures ranked between 2015 and 2016 in NASA’s records.”

    • I’m sorry, just how does anyone know the temperature of the Earth to a hundredth of a degree (C or F it doesn’t matter)????? We don’t so please NOAA, NASA, GISS, and everyone else, stop it!

  9. I take anything coming out of GISS or Hadcrut with a large pinch of salt. They completely lost my trust with their constant adjustments in retrospect and ad-hoc ‘homogenisation’ hocus pocus. I am waiting for the whole raw data sets to be independently vetted and analyzed from scratch by a dedicated team of independent scientists from outside the climate inner circle who are specialists in unevenly sampled data and data with systematic errors. From the Argonne Lab or the National Institute of Standards and Technology, for instance. Until then, don’t bother.

  10. “NASA uses the unique vantage point of space to better understand Earth”

    There have been some big porkers from Climate alarmists, but this takes the biscuit!!

    GISS totally ignore satellite measurements, and only use the extremely sparse, UHI contaminated and heavily adjusted surface temperatures that NOAA and HADCRUT do. (So where’s does this “separate, independent analysis from NOAA” fit in?)

    Independent satellite measurements from UAH give a totally different story, showing that 1998 and 2016 were statistically tied as the hottest years since 1979.

    The reality is that there has been no increase in temperatures since 1998.

    Come on Anthony, fight back against these lies!

    • “UHI contaminated and heavily adjusted surface temperatures that NOAA and HADCRUT do. ”
      and
      “The reality is that there has been no increase in temperatures since 1998.”

      No, the reality is that you choose the far cold outlier UAH (not forgetting the important and not of course adjusted lower V6.0) as your metric of choice.
      And please show me where any UHI contaminated station data affects to even the slightest material degree the GMT estimates of GiSS, Hadcrut, Best, JMA.

    • This from Tony Heller shows why this is so bogus. Compare the map of the alleged anomalies and the map of where they actually have records. Remarkable how they have supposed hot spots – e.g. SW of Baja and in the Indian Ocean – where they have NO records.

      Same for the Arctic where they extrapolate huge areas from almost no data. And I suspect, but do not know, that the data they do have there is compromised by site factors.

      This whole thing is THE greatest scientific f r a u d in history. Just follow the money and its political aims.

        Nick, I would guess Mick meant square kilometers… since that is a measurement of area. Wouldn’t you?

        Say, for example, and area 500 km by 400 km. What he said was true and in some cases an underestimate. Just look at the Arctic, where all that claimed heat is not really being recorded at all.

        Do you think the few real Arctic weather stations are anywhere near buildings?

      On the satellite chart, 2016 is the hottest year, being 0.1C hotter than 1998, and as you can see, other than 2016, the last five years have *not* been the hottest years during this 1979 to 2017 timespan. The year 1998 was hotter than all of them except 2016. There goes NASA and NOAA’s narrative out the window.

      And then Hansen says the 1930’s was 0.5C hotter than 1998, which makes it 0.4C hotter than 2016, which means we have been in a temperature downtrend since the 1930’s, not an uptrend. We have been in a shortterm uptrend since about 1980, but have not equalled the heat of the 1930’s yet.

      Tack Hansen’s 1999 surface temperature chart onto the UAH satellite chart (they overlap from 1979 to 1999) and you will get a good representation of what the Earth’s temperature has been doing since the 1930’s: Cooling.

      NASA and NOAA act like the satellites don’t exist. We know why, because they are not nearly as scary-looking as the bogus Hockey Stick surface temperature charts that have been manipulated to present a false picture of Earth’s temperature profile, in order to sell the CAGW narrative to an unsuspecting public.

      • “Tack Hansen’s 1999 surface temperature chart onto the UAH satellite chart (they overlap from 1979 to 1999) and you will get a good representation of what the Earth’s temperature has been doing since the 1930’s: Cooling.”

        Err…
        That “Hansen” graph is for the US.
        Not the Earth – though I know many denizens think that the US is.

      • Toneb, yes. But in that case the good ole US of A is heavily over-represented in the global temperature stakes.Is that a bias?

      • “Toneb, yes. But in that case the good ole US of A is heavily over-represented in the global temperature stakes.Is that a bias?”

        If that were the case then, then you truly would have cause to complain.
        But of course it’s not and cannot be.
        The USA is 1.9% of the Earth’s surface and so 1.9% of global temperature data is from the US.
        Sorry to burst your bubble … but it should be common sense.

        That the US has a dense data network does not skew the GMT as it is done on an areal basis.

      • Yes, it is done on an “Area” basis, smearing Temperatures over 1200km, when 2 places 1 km apart can have wildy different temperatures.
        And they call it Science.

      • “The planet’s average surface temperature has risen about 2 degrees Fahrenheit (a little more than 1 degree Celsius) during the last century or so, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere”.

        I see they have settled on claiming the warming in the first half of the 20th century is due to “human-made emissions”. Even though the amount of our emissions was insignificant in comparison to natural sources, and natural sinks in the carbon cycle. And the IPCC has admitted as much. Although less so in recent years. It was a logical condemnation of the entire conjecture, so the hockey team has determined the best course is to claim all warming is now anthropogenic in origin. It adds a certain consistency to their claims, but gets them ever more leveraged in their faith of the ability of the magic molecule to determine “what is, what was, and what should never be”.
        When you have to doctor your data and make claims that the math does not support, you have left the realm of scientific analysis, and are firmly positioned in the political science arena. Where perception is more important than reality, and feeding superstition to a willing vocal demographic is enough to keep the gravy train rolling down the tracks.
        Statistically we have very real concerns of cataclysmic events that will occur in the future. But mostly they occur in geological time frames that are orders of magnitude longer than our puny existence.
        The problem is none of them are linked to our behavior, and the only thing we can do is prepare.
        Those solutions do not involve surrendering the production, distribution, and consumption of energy into the hands of people that currently have no legal claim to those assets. Greed and the lust for power are still powerful motivators. And when you jump on that merry-go-round it is difficult to plan a graceful exit, when it only spins faster with the passing of time.

      • Not only that, but at least a half of the warming is purely down to “Adjustments” as identified by NASA/NAOO?GISS themselves.

      • “Err…
        That “Hansen” graph is for the US.
        Not the Earth”

        The Hansen 1999 U.S. surface temperature chart is a good proxy for the entire Earth. Much better than the bogus Hockey Stick charts.

        Just about any unmodified temperature chart you look at has the same temperature profile as the Hansen 1999 chart, which shows the 1930’s to be as hot or hotter than subsequent years.

        Fraudulently manipulated Hockey Stick charts do not show the 1930’s as being hotter than subsequent years. They don’t resemble unmodified temperature charts at all. What they resemble is the CO2 chart, which is the purpose of the fraudulent manipulation.

        Show me an unmodified chart that resembles the Hockey Stick chart. You can’t. I can show you a lot of unmodified charts that resemble the temperature profile of the Hansen 1999 chart: hotter during the 1930’s and cooler since.

        If a temperature chart profile from one part of the Earth resembles all the other unmodified temperature chart profiles, then you have to say that the one represents all of them.

  11. Interestingly we had a cold record breaking winter at the beginning of the year, then we had Spring Frosts all over the place destroying crops, then a standard summer followed by an early onset of winter, 2 to 6 weeks early in some places followed by cold record breaking winter weather all over the world with cold springs in the Southern Hemisphere to match.
    All this adds up to the 3rd hottest year on record.

      • You keep bringing up that GISS Rubbish, I am talking about real life data from around the world.
        Not made up Crap from 1200Km away.

      • Compare and contrast

        Compare and contrast what? You can choose whatever base period you want here

        https://data.giss.nasa.gov/gistemp/maps/

        Selecting the 1981-2010 base period gives a GISS anomaly for 2017 of 0.49 deg. The UAH anomaly is 0.38 degrees. So while they don’t totally agree they are not a million miles apart.

      • Giss just chooses the rise out of the coldest period in 80 or so years.

        Get more RED !!

        Its all just propaganda pap, you know it.

      • “You keep bringing up that GISS Rubbish, I am talking about real life data from around the world.”

        Which is ???

      • The Information reported by the Individual Countries themselves. ie before NASA/GISS mangle the data.

      • Always good to see Australia represented where there are large areas with no data in real life. Infill anyone.

      • “The Information reported by the Individual Countries themselves. ie before NASA/GISS mangle the data.”

        They don’t “mangle the data.
        it would be straight forward to verify that conspiracy theory.
        But then a conspiracy is a conspiracy precisely because there is no proof.
        You do realise that that sort of thinking is bizarre (rhetorical).
        Don’t you think (just as a FI) that those other countries might vehemently object? (again rhetorical sadly)

        The GISS temp map comprises “real life data from around the world”.
        So you give a gross misrepresentation of the facts.

      • You are obviously unaware of the Icelandic data if you think that.
        GISS “Quality Controlled”, ie ADJUSTED the data that the Icelandic Met Office had already adjusted, removing the hot period in the middle of the 20th century.
        You take everything they put out as gospel when it has been clearly shown to be falsified data.

        Can you explain to me and everybody else on this Forum the justification for NASA/NAOO adjusting the Global Temperature for 1997 as reported by themselves in 1998 from
        62.45F or 16.92C
        down to
        58.13F or 14.53C

        Do you honestly expect us to believe that mostly the same Scientists in 1998 could actually get the calculations wrong by over 2 Degrees C.
        But not just for that year but also 1995 and 1998.

      • “You are obviously unaware of the Icelandic data if you think that.

        What an Irony when we have you as an example and the other one posting up doctored graphs from agenda driven Blogs, when all you have to co is go to the orginating paper. Like you should do for SkS and SoD also.

        And I am aware, and actually I thought that goal-post shift would crop-up
        Now show me where that affects the GMST.

        From Nick Stoke’s website ….

        https://moyhu.blogspot.co.uk/2012/01/reykjavik-and-ghcn-adjustments.html

        “No, history was not rewritten. What the folks there don’t seem to want to acknowledge is that GHCN circulates two files, described here. The file everyone there wants to focus on is the adjusted file (QCA). This, as explained, has been homogenized. This is a preparatory step for its use in compiling a global index. It tries to put all stations on the same basis, and also adjust them, if necessary, to be representative of the region. It is not an attempt to modify the historical record.
        That record is contained on the other data file distributed – the unadjusted QCU file. This contains records as they were reported initially. It is generally free of any climatological adjustments. For the last 15 or so years, Met stations have submitted monthly CLIMAT forms. You can inspect these online. Data goes straight from these to the QCU file, and will not change unless the Met organisation submits an amended CLIMAT file. This is the history, and no-one is tampering with it.
        The adjusted file does change, as the name suggests it may. Recently, it has been modified to use an improved pairwise comparison homogenization algorithm due to Menne and Williams. It is now (as of Dec 15 2011) used by GISS instead of their own homogenization algorithm, which makes the QCA file much more significant.”

        Again show me where so small matter of Icelandic temps altered the GMST.

        “Do you honestly expect us to believe that mostly the same Scientists in 1998 could actually get the calculations wrong by over 2 Degrees C.
        But not just for that year but also 1995 and 1998.”

        So they are in a conspiracy to commit fraud?
        Quite, quite bizarre.

      • Exactly.
        Even the Satellite data does not refelct what we are actually experiencing and I have been saying so for years.
        Satellites measure the Energy leaving the Earth.
        GISS just make it up as they go along, as do the Australian BOM.

      • “That map flies in the face of what the locals experienced.”

        Which “locals”
        Bearing in mind that (if posted by me) is a December average, and not the extreme.

    • Most of the data is made up and fake using limited surface station data, especially around polar regions, southern hemisphere and Africa. NASA can claim what ever they feel like because they control it. In reality can’t compare apples with oranges and expect a reasonable like for like comparison from 1951-1980. Exaggeration of any warming planet is not science, but they have chosen this route unfortunately. There are none to compare for most of the planets surface away from North America and Europe before the satellite era.

      While it is also expected to have some of the warmer global temperatures recently when there had just been a strong El Nino.

      There was no observed data between 1951-1980 for data to be compared with for most regions showing red in the NH.

  12. The natural warming trend from the little ice age continues…. until it doesn’t. Then it cools again, naturally.

    • As I keep say, The warming has come ONLY from the oceans.

      There is NO WARMING apart from the two main ocean RELEASES of energy.

      • Not CO2, that is for sure.

        Almost certainly the series of strong solar cycles over the latter half of last century.

        Changes in UV and other cause more energy to penetrate the ocean.

  13. What became of the 1998 El Nino Spike? It clearly shows in all the NZ weather station (and satellite) data and the trend since then (coming up 20 years) is FLAT

    Also: my understanding is that the International standard for establishing anomalies is based on using the period 1981 – 2010 as the baseline. Why are these 2 institutions using a different baseline?

    The 2 well established factors that should be keeping alarmists awake at night are:

    – There has been no significant warming for 20 years

    – Over 95% of model predictions have been grossly WRONG! – proving that they are useless

  14. “Despite colder than average temperatures in any one part of the world, temperatures over the planet as a whole continue the rapid warming trend we’ve seen over the last 40 years,” said GISS Director Gavin Schmidt.”

    Isn’t there some law that requires government officials to not tell such ridiculous unfounded whoppers?

    Time to defund this garbage.

      “Despite colder than average temperatures in any one part of the world, temperatures over the planet as a whole continue the rapid warming trend we’ve seen over the last 40 years,” said GISS Director Gavin Schmidt.”… Time to defund this garbage.

      As a statement of fact, it can’t really be argued against. Even taking the coolest of the global data sets over the past ~40 years (since 1979), satellite data from UAH TLT, the statistically significant warming trend has continued in 2017; actually increased slightly.

      From 1979 to 2016 the trend in UAH TLT was 0.113 ±0.063 °C/decade (2σ). Adding 2017 data raises this to 0.124 ±0.062 °C/decade (2σ). With the addition of 2017 temperatures, the overall warming trend in UAH TLT increased slightly and the margin of error shrank marginally too.

      What’s that if not a continuation of warming?

      Source: http://www.ysbl.york.ac.uk/~cowtan/applets/trend/trend.html

      • DWR54 – From that blunt perspective, for that whole (short) period, true enough – assuming reasonably accurate ‘adjusted’ data. You could make the same point further back, to the bottom of the Little Ice Age.

        Here’s what is not fact: “continue the rapid warming trend.” Given what we know about climate history there is nothing particularly rapid about this trend.

        Moreover, that suggests a continuing trend when in fact it has not been. There was the ‘hiatus’ – which was not forecast by the consensus and does not fit the CO2 rise during that period. Instead it showed that natural variability drives climate change. That, and the fact that we have been on a warming trend since the Little Ice Age, indicates that CO2 is largely irrelevant – in contrast to what Gavin constantly goes on about.

        Of course, like all things now that the oceans are not boiling, that hiatus was extreme.

      • Extreme Hiatus

        Here’s what is not fact: “continue the rapid warming trend.” Given what we know about climate history there is nothing particularly rapid about this trend.

        Schmidt is obviously talking in the context of the surface instrument temperature record, which is what he’s being interviewed about. Recent 40-year trends are the highest on record in all of these. There was a spurt of warming in the early part of the 20th century, but the 40-year trends centred around the mid 1920s peaked at ~ 0.13C/dec. Not until they were centred around the late 1970s or early 1980s did 40-year trends surpass the 0.15 C/dec mark, and they’ve stayed above 0.16 C/dec ever since in all data sets.

        The 40-year period to December 2017 warmed at a rate of 0.182 C/dec, according to GISS, making it a tie with the 40 year period ended Nov 2010. It is reasonable therefore to state, in the context of the instrumental surface data record, that there has been a rapid warming trend over the past 40 years and that 2017 has continued it.

  15. Wait a minute. When I first stepped into a Geology department in 1975, the “average global temperature” was reported and taught as “about” 15C. This was taught as “fact” for decades and decades and decades.

    “Global Warming and Climate Change
    S. K. Agarwal

    A.P.H. Publ., 1 Jan. 2008 – Science – 364 pages

    The earth`s atmosphere is made up of different layers. Gases such as Carbon dioxide, Methane, Nitrous oxide, chloroflurocarbons, Methyl bromide etc. make the atmosphere work like a greenhouse. These gases trap heat emitted by infrared wavelengths from the earths surface. This phenomenon is called greenhouse effect, and is responsible for the average temperature at the earth surface being 15c rather than -15 c the temperature it would be it there no atmosphere.”

    This report is telling us that the “world” is warmer than 13.889C. It has risen to a whopping 14.727778C (give or take a bit one assumes). So “about” 15C.

    This isn’t science. It’s nonsense.

    • “This report is telling us that the “world” is warmer than 13.889C. “
      THis report? GISS? Where?

      GISS is very firm that trying to get an accurate absolute global average is a fool’s errand.

      • “GISS is very firm that trying to get an accurate absolute global average is a fool’s errand.”

        Yet they and there mate claim “hottest evah”, by tiny fractions of a degree.

        Gees Nick, you have serious foot in mouth, today !!

      • “According to NOAA, the average temperature across the globe in 2017 was 1.51 degrees F above the 20th century average of 57 degrees F.”

        They said 57F not “about” 57F. Which is 13.8889C.
        Then 57 + 1.51 = 58.51
        So …
        58.51F = 14.727778C

        As I said, when I did my BEng, BSc and MSc, the global “average” temperature was considered “about” 15C. The planet seems to have warmed at a RAPID rate o “about” 15C. Or s bit less, or a bit more.
        The reason bullshit reports like this can get published is that the great unwashed don’t realise the the Cult of Warmie are just lowering the temperature of the past. When in fact “the climate” is doing nothing at all.

      • i>”They said 57F”
        Who said? Not the GISS report here. Even the linked NOAA report says:
        “During 2017, the average temperature across global land and ocean surfaces was 1.51°F (0.84°C) above the 20th century average.”
        No mention of 57°F there. So who said it?

      • http://www.theaustralian.com.au/national-affairs/climate/earth-colder-in-2017-after-three-years-of-recordhigh-temperatures/news-story/5d52fa989d43642419b13e5a2dcdb05c

        “According to NOAA, the average temperature across the globe in 2017 was 1.51 degrees F above the 20th century average of 57 degrees F.”

        You asked Niclearse

        “Who said? Not the GISS report here. Even the linked NOAA report says:

        NOAA. It may have been removed when keen minds spotted they had lowered the temperature of the past by 1.5C (plus or minus a bit).

        Now is it your contention that they are reporting the HOTTEST YEAR EVER because it is EXACTLY 1.51F over a number they don’t really know? That doesn’t make a lot of sense, like much of the “climate voodo… science”.

        The average global temperature about a century ago was “about” 15C. Fifty years ago it was “about” 15C. Today it is “about” 15C. Or if you like the quasi-science offerings from the Cult of Warmie,
        “about” 14.727778C (give or take a bit one assumes).

        By any realistic measurement basis one can only conclude that climate change has stopped over the last few hundred years to date. Nothing at all is going on, with or without CO2.

    • It is as Mark Addinall says, according to NOAA there’s nothing to worry, earth is running cooler than generally accepted earth’s average temperature, 15 degC / 59 F, derived from settled climate science. Here,s NOAA saying it, Nick.

      “The average temperature across the globe in 2017 was 1.51 degrees F above the 20th century average of 57 degrees F. 2017 marks the 41st consecutive year (since 1977) with global land and ocean temperatures at least nominally above the 20th-century average. The six warmest years on record for the planet have all occurred since 2010.”

      • Mark, this is still here at the moment, but probably won’t be for much longer.

        https://www.ncdc.noaa.gov/sotc/global/199713

        It was their biggest ever mistake of quoting the ACTUAL temperature instead of just an anomaly, they blame the current “difference” of 2C on a Baseline change.
        That is 2C, not some record broken by 0.01C or even 0.1C, 2 whole degrees of change in 20 years.

        You are absolutely correct they are liars & cheats and the likes of Nick, toneb & DWR try to justify it.

    These two were published in the opinion readers response in relation to the above article.

  17. Even though they fudge the numbers, who cares? I still recommend stopping the geoengineering. Brown skies everyday.

  18. The longer term picture….

    That blue section covers the COLDEST 500 years in the whole of the Holocene,

    Before that, we had the Holocene Optimum for some 5000 years, then a gradual 3000 year drop in to that 500 year cold period. Any period up to 9,000 years before this graph would have been WARMER.

    This graph represents the COOLEST1000 years of the whole Holocene.

    It is ONLY during that 500 year period and a short period around the late1970’s – 2006, that sea ice was at a greater extent than it currently is…

    You can also clearly see the 1940s warm spike on this chart as well, on average, about the same as 2000.

    • Here is what Author Rydval had to say about Richard/notrickszone misrepresentation of his graph:

      “Milos Rydval, University of St. Andrews
      In the Rydval et al 2017 article, we clearly and repeatedly emphasize that there is a considerable amount of uncertainty associated with our temperature reconstruction and this generally increases further back in time and is related to, among others, data availability. This point is discussed in considerable detail in the paper and is a matter that was entirely ignored by the source cited in the Breitbart article. Thus, the cited statement: “the reconstruction] suggests that the recent summer-time warming in Scotland is likely not unique when compared to multi-decadal warm periods observed in the 1300s, 1500s, and 1730s” was taken out of context and misrepresented. The cited source conveniently omitted the second part of the sentence which highlights uncertainty in the earlier parts of the reconstruction and includes a cautionary statement about the interpretation of those periods. Also, it should be noted that our study provides information about conditions in and around Scotland, and is therefore not a representation of the average global trends of tem”

    • The match between Iceland sea ice records is quite good., also other similar records.

      Do you DENY that the Wolf, Sporer, Maunder and Dalton minima existed ?

      Do you DENY that they were colder than now.?

      Your DENIAL runs deep Nick… but its all you have to prop up your baseless belief system,

      Further, I have not made ANY comment about anyone else’s comments

      The graph speaks for itself , and aligns well with other data.

      The period from about 1200 -1850ish was the COLDEST period in 10,000 years .

      You KNOW that Nick. Do not continue to DENY facts.

      It is also the ONLY period 650 years out of 10,000 where sea ice extent was higher than now, (apart from the spike in the late 1970s)

      For most of the other 9000 + years sea ice extent WAS LOWER.

      MULTIPLE data displays this FACT.

      End of story.

      • Doctored fakes…. ROFLMAO. !!!

        No Nick, that is YOUR department.

        None of graphs I posted are fakes, especially NOT the Stein graph.

        If you are so mathematically and scientifically inept that you can’t see that NO DATA WAS CHANGED in any way, just the presentation of the graph

        then NO-ONE can help you.

        Is there any change in the data that is conveyed by the graph , Nick? Be Honest ! (as if)

        I agree that the one post just above has error issues,

        MWP should be warmer than they show it.

      • Let’s see if Nick RUNS AWAY from these questions again

        Do you DENY that the Wolf, Sporer, Maunder and Dalton minima existed ?

        Do you DENY that they were colder than now.?

        Do you DENY that a large proportion of the Holocene before those 650 or years COLDER years, was WARMER than current temperatures?

      • “especially NOT the Stein graph”
        Well, lets look at it again:

        There seems to be a simple rule here. Any genuine text has been distortd by re-scaling. If it isn’t distorted, it’s fake. Your presentation clearly represents that it is a graph from Stein et al.

        So he’s added an x-axis. Fake but accurate. And the annotations. Fake but maybe. But the heading? Fake and a lie. Stein made no claim that they were graphing “Holocene Sea-Ice cover variations”. Yet these words are prominantly attributed to them. Their graph makes it quite clear that they are graphing biomarker indices found in a sediment core, ARA2B-1A, in the Chukchi Sea.

      • The graph most certainly IS from extracted Stein et al.

        You have shown that yourself.

        Has the data been changed?

        Are the annotations misleading or incorrect?

        The graph conveys EXACTLY the same data as the original.

        It is NOT “FAKE” nor is it a misrepresentation of the original graph.

        It is note that you YET AGAIN, avoided answering the 3 questions

        Do you DENY that the Wolf, Sporer, Maunder and Dalton minima existed ?

        Do you DENY that they were colder than now.?

        Do you DENY that a large proportion of the Holocene before those 650 or years COLDER years, was WARMER than current temperatures?

      • He DID NOT add an x-axis.

        He transferred it from the left of the irrelevant graphs.

        Again, anyone can see that NO CHANGES were made to the data conveyed by the original graph

        Many other graphs back up the TRUTH of The first 8000 or so years of the Holocene being significantly WARMER than now, and nearly always having far LESS sea ice than now, often being summer ice free.

        Interestingly, if you rotate the Stein graph 180 it aligns rather well with the GISP ice core data.

        Funny about that. :-)
        Now, about those 3 questions Nick

        Do you DENY that the Wolf, Sporer, Maunder and Dalton minima existed ?

        Do you DENY that they were colder than now.?

        Do you DENY that a large proportion of the Holocene before those 650 or years COLDER years, was WARMER than current temperatures?

      • “He transferred it from the left of the irrelevant graphs.”
        No. As I said, the tell is that genuine text is distorted. In fact, the label is different text, and the numbers have been rotated. Fake but accurate. It’s good that he was able to accurately construct an x-axis, but we should be told that this is happening.

      • You are WRONG Nick. They are in the correct position, Yes the axis has been stretch but again

        answer this question

        Has the data conveyed by the graph been altered in ANY WAY WHATSOEVER ?

        Simple question , Nick. Easy Peasy. !!

        It is AGAIN noted you avoided the other three questions

        EVERYBODY can see you squirming around them Nick.

      • Are the x-axis numbers in the wrong place , Nick..

        Yes or No.

        There is NOTHING mathematically or scientifically wrong with making a graph more legible.

        So long at you don’t change the data the graph conveys.

        Has the data conveyed been changed in ANY WAY AT ALL, Nick ??

        You KNOW the answer is NO, but you are just to pig-headed to say it.

  19. I thought the Twitter POTUS was going to stop both NOAA and NASA from atmospheric sciences, and especially reporting that this is all down to CO2. This is a very biased report.

    Nothing has changed, I think your man has lost his agenda. When is the red team blue team thing happening, or did I miss it.

  20. EL Ninos and La Ninas are temporary features of the ocean and must not be included in calculations to determine which year is warmest. If you take iut the large El Ninos used in calculating the warmest year you are likely to find that 2017 was not the warmest year on record.

    • 2015, 2016, 2017 all have warming facets from the N Atlantic Blob and the El Nino.

      A lot of energy was released from the oceans in those three years.

      (What happens to an object when it releases energy?)

      Its taking a while to dissipate, but it will be interesting to see where we are in 6-12 months time. :-)

  21. “The combined global average temperature over the land and ocean surfaces for November 2017 was 0.75°C (1.35°F) above the 20th century average of 12.9°C (55.2°F). ”
    from …..https://www.ncdc.noaa.gov/sotc/global/201711

    However NOAA also thought the twentieth century average temperature was 15.5° C [59.9°F].
    https://www.ncdc.noaa.gov/sotc/global/201706

    Errrrr, yes, well……

    So was the temperature over or below the average, what was the average..?

    • Greg, you are correct, they keep changing their minds about the Averages, as they have to, because they keep lowering the historic data.
      They are continuously calling themselves liars.
      Just look at the 1998 report for 1997 to see it for yourself.
      1997 used to be 62.45F or 16.92C, now it is 58.13F or 14.53C.
      Soon it will be even lower.

    You’re confusing annual and monthly values. One of your linked reports is referring to June, the other to November. All months have different absolute temperature reference values. The annual value is the average of these: https://www.ncdc.noaa.gov/monitoring-references/faq/anomalies.php

    In any case, the point of a temperature record as used in climatology is to monitor ‘change over time’. You can do that using anomalies irrespective of what the absolute starting value is.

    • PS See the ‘Mean Temperature Estimates’ link in the above NOAA link for their estimated absolute mean temperature values for each month.

    • The utility of using anomalies “irrespective of what the absolute starting value is” depends on the baseline from which the “anomaly” is determined, is dependent on the accuracy (not precision) of the estimated values and changes, and is of value in the presentation of climatic trends only to obscure the actual temperatures being measured and press a narrative. It’s of little use other than that. It is hugely irrelevant when there is clear evidence of collusion to change past data to support alarmist claims. It’s a statistical trick the way it’s used by the CAGW practitioners, and statistics used in the way they do have more to do with presentation of a viewpoint to influence political thought than with “monitoring change over time.”

      Graphs with a hugely magnified y-axis scale to show dramatic changes in “anomaly” and the resulting exaggerated linear trend is far scarier to the ignorant than is a graph showing the actual small fluctuation in the estimated global mean temperatures over a long period of time, including error bars.

      If you show a graph, using a reasonable Y axis scale, of the estimated annual global temperature – including error bars – for the past 150 years or more – people would yawn and say “where’s the crisis?”

      If you use anomalies to monitor change over time, you have to stop at present time without pretending that you are doing anything more than monitoring change over time. Adding a linear trend line to a segment of data of questionable accuracy (because error bars are excluded) over a snippet of time and implying that said trend line is an absolute predictor of future anomalies is disingenuous at best.

      If you include error bars, you can see that the claims of one year being 2/100 of a degree Fahrenheit warmer than another is a fallacy because the instruments measuring the raw data are an order of magnitude less accurate than that, and that most of the alarmism is over small fluctuations within the statistical margin of error.

  23. So by extension the public is to believe El Nino heat is trapped in the Arctic region forever? Good luck with that and better line up the next message management shift to another part of the globe. Just keep the cold anomalies stationed over NY, Boston, and Paris. That would be optimum climate conditions.

  24. Well into the fourth decade of this “unprecedented” warming, and the common consensus among the taxpayers is “If it gets any warmer, I’m going to freeze my ass off”!
    And NASA responds by redoubling their propaganda efforts. I am especially impressed with their manufacturing of global data back to 1880. The civil servants that were taking temperatures in life-threatening conditions all over the world, with no modern conveniences in transportation and communications, and faithfully reporting the results, are much more impressive than the current crop, we are paying top dollar to get top shelf fabrications. It amazes me how we got so much data, from such a trifling of measurement. I guess when you already know the answer, the questions are greatly simplified. /sarc

  25. And the grand solar minimum continues apace with record cold and snow the reality. Where is the explanation in AGW of this simple fact?

  26. These raw measurements are analyzed using an algorithm that considers the varied spacing of temperature stations around the globe and urban heating effects that could skew the conclusions.

    A penetrating dissection of GISS’s vaunted algorithm reveals that the word “considers” hides the fact that it arbitrarily “homogenizes” disparately spaced station records and does nothing effective to eliminate UHI bias in a predominantly urban data base. Their whole claim here is bogus science.

  27. To generalize about ‘average’ global temperatures requires perhaps more scientific data than we now possess. But certainly, the ‘science’ on this topic going back 100 years or more is woefully inadequate.

    It requires millions of temperature-measuring instruments around the globe to get an accurate picture. This is a modern endeavor, requiring satellites. Our knowledge about past ‘average’ global temperature is therefore guesswork, much of it politicized. Any claim about average global temperatures a century ago is fraudulent. There’s simply too much missing data.

    Interestingly, our current so-called ‘warming’ period is being compared to an era where temperatures had allegedly been dipping (1950 – 1980) from previous ‘norms’. 1950-1980 was the calamitous ‘global cooling’ era. Have you forgotten?

    The phenomena of ‘global cooling’ was a big deal in the 1970s. I wrote about it as a young journalism student in 1975. Fact: ‘global cooling’ was scientifically measured and ‘real’. And it threatened humanity! ‘Global cooling’ was also hyped heavily by the mainstream press of that era. Amazing, but true. ‘Average’ temperatures did measurably decline during this era.

    Perhaps today’s ‘warming’ is merely a return to ‘normal’ temperatures. No one knows. It’s all been horribly politicized.

    In any event, our so-called global warming is not responsible the the enormous environmental destruction that has ensued with the rise in human population. The human family grows by about 75 million people every year. This is the core problem.

    It is human hunting, human-caused pollution and human caused habitat destruction that are the real culprits here. AGW is not the problem. In fact, slightly warmer temperatures might be a boon to humanity. No one knows for sure. But the unprecedented rise of human numbers is taking a terrible toll on our natural world.
