NASA reports 2010 hottest year on record so far

Last month, NASA reported it was the hottest January-September on record.  That followed a terrific analysis, “July 2010 “” What Global Warming Looks Like,” which noted that 2010 is “likely” to be warmest year on record.

This month continues the trend of 2010 outpacing previous years, according to NASA:

October 2010 NASA

It now seems pretty certain 2010 will outpace 1998, which currently ties for fourth hottest year in the NASA dataset (though it is technically described by NASA folks as tied for the second hottest year with 2005 and 2007).

Outpacing 2005, the hottest year on record, will be closer.  In NASA’s surface-based dataset, we are unlikely to set the record monthly temperatures for the rest of this year; last month wasn’t close to the hottest October for NASA, though it was third warmest.  We  have entered a moderate to strong La Ni±a, which NOAA says is “expected to last at least through the Northern Hemisphere winter 2010-11.”  That said, as you can see, the October anomaly (deviation from the 1951-1980 average) was higher than September, in spite of the La Ni±a.

NASA’s surface-based temperature record appears to be the most accurate, as I’ve noted many times (see Finally, the truth about the Hadley/CRU data: “The global temperature rise calculated by the Met Office’s HadCRUT record is at the lower end of likely warming”).

As I discussed earlier, last month, the hottest September in UAH satellite record, puzzled Roy Spencer with its “stubborn” temperatures.  He now concedes that this year is likely to tie 1998 for the hottest year in the UAH satellite record (see “January-to-October tied for hottest in satellite record“).

For what it’s worth, here’s the latest UAH data, which, at least until it’s ‘adjusted’, shows what appears to be the warmest early November on record:

UAH 11-10+

UPDATE:  Michael in the comments directs us to this map of recent temperature anomalies from NOAA, which shows remarkably warm temperatures over much of Northern Hemisphere:

Finally, it bears repeating that the record warmth we are seeing this year is all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,” as a recent must-read NASA paper noted:

It is just hard to stop the march of human caused global warming “” other than by sharply reducing greenhouse gas emissions.

  1. BillD says:

    And there are still people who claim that “warming stopped 12 years ago.’ I hope that 2010 sets a new record, so that deniers can come up with something new. Maybe they will even agree that it makes sense to analyze trends, rather than focusing on annual records.

    I can’t remember when we have had day after day of highs in the mid to high 60’s (oF, about 20oC) in the US Midwest well into November. Although warming and climate change is generally a disaster for humans and other species, I must admit that I am really enjoying taking 15 minute walks after lunch this week, without a jacket and with the sun shining on my face.

  2. Mark at the Rally says:

    BillD, unless 2011 is hotter than 2010, the deniers will proclaim, “See, the earth is cooling!” using two years as a “trend.”

  3. Dean says:

    Undoubtedly the deniers will claim that the third warmest month means it’s actually getting colder, just like having the second or third smallest arctic ice extent means the ice is growing.

    Over at Michael Tobis’ Initforthegold, he reports on an organization that thinks that 650ppm CO2 is the best we can hope for now. Such hope.

  4. Colorado Bob says:

    Temperatures in the Russian capital soared to a record high for November on Wednesday, hitting 13 degrees Celsius (55.4 degrees Fahrenheit) by midday, the Moscow Weather Office said.

  5. Colorado Bob says:

  6. L. Carey says:

    @Dean – actually the info that Michael Tobis refers to is from a submission submitted by 4 grad students in an MIT contest for climate policy proposals (not a formal projection by MIT). (It’s still not comforting that they would conclude that 650 ppm is tolerable and the best we can hope for.)

  7. Roger B. says:

    For the first 10 days of November, northern North America has experienced substantially above average temperatures: Prudhoe Bay (AK) +12.70 F (7.06 C); Churchill, Manitoba +13.75 F (7.64 C); Iqaluit, Nunnavut +14.30 F (7.94 C); Yellowknife, Yukon +14.00 F (7.78 C), Regina, Sask. 12.75 F (7.08 C), Goose Bay, NFL +6.90 F (3.83 C)and Moosonee, Ontario +6.05 F (3.36 C).

    Much of Eurasia is also experiencing significantly above average temperatures:

  8. Mark S says:

    I’ve been tracking the UAH near surface temps (ch04) and for the Jan-Oct time period 2010 is the hottest, beating 1998 by .01 c. Not much but it’s certainly hotter. Also, mirroring the graph Joe provided the near surface anomaly for Nov currently stands at .63. The old record for November was set all of 1 year ago at .50.

    This is using the publicly available data and not the re-adjusted temps that Dr. Spencer will publish.

  9. catman306 says:

    Does anyone really think that there will be any humans alive that could read scientific instruments that would indicate a reading of 650 ppm CO2? There will be a myriad of extreme weather events and other weather related geologic catastrophes before we get to 650 ppm. That bad weather thing is a killer. So are starving humans.

    The Pakistani Flood Tax –

    Pakistan has announced mid-year measures to raise more than $700m (£435m) to support people affected by the monsoon floods over the summer.

    The move comes amid growing pressure from western donors that Pakistan should first tax its own rich before it seeks international help.

  11. Colorado Bob says:

    A study of flood damage conducted by the World Bank and the Asian Development Bank have put total losses at about $9.7bn (£6bn).

  12. Barry says:

    It seems likely that 2010 will indeed beat 1998 as the hottest year in the Spencer’s UAH satellite data.

    He says that the two years are statistically tied for jan-oct. So it comes down to whether nov and dec this year will significantly top the same months in 1998.

    His dataset shows november 1998 was not very warm compared to recent novembers with “only” 0.19C warming vs average.

    For this november, as Joe points out above, the UAH data shows every day so far as the hottest for that day in the dataset. Every day listed has an anomoly greater than 0.30C.

    A record hot start to November…in the hottest year so far…all documented by the denier’s favorite dataset…and happening during both a La Nina and a solar minimum.

    What where the GOP leaders thinking by forcing their politicians to kowtow to the meme that climate change is a “hoax” and to sign their names to a “pledge” to do nothing about it.


  13. GFW says:

    Catman, there will be humans at 650 ppm. But probably quite a few less, and under serious stress conditions.

  14. Peter M says:

    Global temperature to rise 3.5 degrees C. by 2035: International Energy Agency

    Unless governments cut subsidies for fossil fuels and adopt new policies to support renewable energy sources, the Copenhagen Accord to hold global warming to less than a 2-degree increase will not be reached.

  15. Michael Tucker says:

    “It is just hard to stop the march of human caused global warming — other than by sharply reducing greenhouse gas emissions.”

    That’s right Joe. It is slso hard to stop the relentless “march of human[‘s].” With almost 7 billion of us here now we have managed to radically change the climate, change the chemistry of the oceans, and threaten a great deal of the other species who share Earth with us. No other species requires so much of the planet’s recourses to live or generates the vast amount of ecologically harmful waste that humans do.

    Our species is in a very difficult situation and many of us are unaware of the situation or unwilling to address the problems.

    Climate Change Linked Disasters Push Food Prices Higher

    Massive Natural Disasters Fuel Global Grain Price Spike

    This month, the Wall Street Journal reports that prices of basic foods like milk, beef and cereal grain have risen sharply enough in the U.S. in recent weeks that major food producers like Kraft and General Mills have decided they must begin to pass the increased cost of supplies on to their customers in the form of higher retail food prices.

    After months of notably low inflation, what could be driving this sudden rise in food prices? Contrary to former vice presidential candidate Sarah Palin’s recent claims, it’s not current American economic policy that’s to blame for the rising cost of certain foods. It’s the weather.

  17. Paul Klemencic says:

    Following up on Joe’s and Barry’s thoughts: I am finding the satellite data disquieting. The highest November anomaly was last November at 0.50, and this year’s daily data for November should be quite comparable to last November’s data. (For 1998 data collected by a different satellite, the comparison of daily data is more problematic.) So it seems, that we have a good shot at seeing the November 2010 anomaly exceed 0.50.

    But this month should not be hotter than November 2009… something is clearly wrong, and maybe terribly wrong. Last year we were at the peak of a moderate El Nino; this year we are now in the depth of a strong La Nina. Even worse, this isn’t a one month trend; the October and September
    UAH anomalies also exceeded the corresponding 2009 months, and they should not have.

    Roy Spencer is puzzled for a very good reason. The planet’s atmosphere seems to have jumped to a higher heat level. Why? We really don’t know.

    There are some alarming methane readings from some of the northern monitoring sites, that may be connected with the huge warming trend in Siberia and shallow areas of the Arctic ocean. Couple this with the heat wave in Russia, and anecdotal evidence of loss of permafrost in Siberia, Alaska, and northern Canada, and it seems we may be into a potentially catastrophic melt of permafrost areas in the NH. Look at the GISS map above, and readers will notice the largest warming is over some of the major permafrost areas.

    Permafrost is estimated to hold about 73,000 cubic miles of water (see the nice table at the
    USGS link showing how this compares to world water distribution). In general, permafrost seems to be about 20% ice embedded in the ground materials (soils, sand, rocks and gravel). A loss of 1% of the permafrost annually, with the temperature of both the water and ground rising from minus 4 to minus 10 deg C to a ground temperature in the 2 to 6 deg C range would use about 14 x 10^20 joule per year. Compare this to the roughly 2 x 10^20 joule per year estimate for heat building up in the atmosphere.


It seems that melting permafrost might absorb about an order of magnitude times the heat accumulating in the atmosphere due to global warming. A quick search on Google Scholar didn’t find any directly relevant hits for research on this topic.

    If the permafrost is melting out, then we would expect to see higher methane concentrations in the NH, and since the cooling effect of the permafrost in the summer and early fall is diminished, we should observe higher temperature anomalies in these regions during those timeframes. The global temperature anomalies seem to be showing just this.

    This is just an educated guess, but the global anomalies seem to be signaling a shift to a higher temperature state for the planet.

  18. Gordon Parish says:


    2010 generally makes me feel poetically melancholic:

    Plenty of heat hanging in the air
    Smoking vapors choking me
    Sometimes it’s hard to care

    The sun has scorched everything in sight
    It glares from empty skies
    The children wilt under this blight
    Can no one hear their cries?

    Where are the sheltering trees?
    Save us from this sweltering heat!
    Show me just one cool breeze
    And I’ll lead us from defeat!

  19. Colorado Bob says:

    Been looking at that coral die-off story closer . We knew this was coming, 1 month ago, there were scattered reports on the green blogs in several wide spread locations. This first hand report from Panama is chilling :

    “I’ve never seen bleaching like [it] in Panama,” said Nancy Knowlton, a coral biologist at the Smithsonian Tropical Research Institute in Panama who has been studying the local flora for 25 years. She and colleague Hector Guzman have seen massive reefs die in recent weeks in the enclosed lagoon of Bocas del Toro in Panama after becoming coated with giant sheets of slime, the remains of dead microorganisms. “This is NOT a normal condition on reefs, even bleached reefs. Where last year there were healthy corals, this year there was only gray ooze,” she wrote in an e-mail.

    Now comes the Scientific American with their world wide article …….
    Major, Worldwide Damage to Corals Seen This Year

    Scientists blame unusually warm ocean temperatures this year for the mass devastation of the world’s corals

    Seems the coral biologists are all saying the same story , this report is from Asian waters …..

    ” “My colleagues and I have high confidence these successive ocean warming episodes, which exceed the normal tolerance range of warm-water corals, are driven by human-induced global warming,” said Dr Baird.

    “They underline that the planet is already taking heavy hits from climate change – and will continue to do so unless we can reduce carbon emissions very quickly.”

    A report out of Madagascar :

    Oct. 15, 2010 – IUCN scientists were part of a recent expedition, Tara Oceans, to investigate coral bleaching on the reefs of Mayotte, an island that lies to the north west of Madagascar. The team found that bleaching here, which was first reported in March this year, is the worst seen in the Indian Ocean.
    This story needs to get bumped up the news food chain.

  20. David says:

    A little more on the UAH satellite data that the deniers love to quote… November and December need to average .40C for a new record. So far, November is running well ahead of 2009 (according to the Channel 5 AMSU data), which is the warmest on record at .50C. If November finishes above .5C, all December would have to do is finish around or even below .30C to have a new record.

  21. There will be a negative feed back, not of the usual kind, when gas prices skyrocket as supplies become tighter. That might be just around the corner.
    It’s going to be a difficult for everyone but the very rich.

  22. David says:

    The bottom line is global warming continues unabated. And, sorry Barry, for essentially re-stating what you had written. I didn’t read all of the comments before making my last post.

  23. Prokaryotes says:

    Looking at the UAH graph the 2010 line is more active, has more pronounced curves/spikes. The numbers – rising amounts of heat trapping gases and temperature rise accelerates.

    So far positive feedbacks dominate and with tar sands, mountain top removal and massive human methane/natural gas exploitation negative feedbacks, will be just noise or temporarily distractions from volcanic eruptions.

    I wonder how long till we witness bigger uptakes, i.e. from permafrost melt – methane deposit destabilizing or mega disasters.

  24. Prokaryotes says:

    I see now that the other lines represent average values. Nevertheless, i guess the data should become more chaotic/active.

    A Poem (with a message for our leaders)

    I love Art

    I always love
    A Happy Face

    Will we admit
    We need some verve

    The world, it turns
    A fever brews
    We must dig down
    And find our muse

    To signal when
    To tell us “Now!”
    It’s time to end
    The sacred cow

    That gives us coal
    That gives us oil
    That wants to make
    The climate boil

    And all for what?
    A dividend?
    How sad, that’s how
    The world may end!

    So hear you now
    And hear you me
    I think it’s plain
    For all to see

    We need more hard
    We need less soft
    Or else, alas
    All bets are off



  26. Steve Bloom says:

    Re #18: Paul, I don’t think it’s possible for permafrost methane releases to result in noticable on-the-spot warming. Methane just isn’t effective enough as a GHG to do that, besides which winds mix it gloabally pretty quickly. I don’t know enough to really say, but the ice-albedo feedback might be able to have such an effect, although we’d want to connect the dots before making such a claim about the present warm anomalies. Remember that climate patterns seem to shifting, with a new pattern emerging in the Arctic in particular, which seems to me to be a more likely cause (bearing in mind the difficulty of drawing any conclusions from short-term weather behavior).

  27. Prokaryotes says:

    Steve Bloom, Methane is not evenly distributed through the atmosphere.

    If vast methane deposits enter the atmosphere you will have land hovering explosive gas bubbles and huge quantities of oxygen will be lost from the chemical reactions.

  28. Esop says:

    It shall be most interesting to see the reaction of the “skeptics” if the UAH series breaks the 1998 record, and it certainly seems that it will, unless the data are… ahem.. adjusted.
    If UAH puts 2010 in the #1 spot, but GISS and HadCrut won’t, that will cause some rather interesting reactions in the “skeptic” camp. Will they all of a sudden abandon UAH and embrace GISStemp?

  29. Duncan says:

    speaking of high temperatures, has anyone seen this link

  30. Paul Klemencic says:

    Steve Bloom, I am not saying the methane caused the regional heating. I am suggesting that the permafrost is melting out much faster than people expect, and the resulting increases in ground temperatures, as well as warming in the shallow areas of the Arctic ocean, are releasing more methane. The methane and regional warming are both signals of a loss of permafrost and rises in regional ground and water temperatures in permafrost areas. (Incidentally, there was a recent report from Canadian authorities warning about the loss of permafrost in the MacKenzie delta area due to warming.)

    The satellite temperature anomalies are running much higher right now than anyone would have predicted at the beginning of the year, considering the severity of the La Nina and how sensitive these anomalies are to the ENSO cycle. These record monthly anomalies clearly are outside of our prior experience with previous La Nina events.

    I am just looking for an explanation why.

  31. Colorado Bob says:

    2 months ago –
    Of real concern: the scale of the sea surface temperature anomaly, which has affected the entire Andaman Sea and beyond. Similar mass bleaching events of 2010 have now been recorded in Sri Lanka, Thailand, Malaysia and many parts of Indonesia. If this scale of mortality is found at other sites, the event will enter the record books as the worst bleaching ever recorded in the region. WCS Marine Program Director Dr. Caleb McClennen tells WCI:

    Massive Coral Bleaching Damages 95% of Corals in Philippines

    RE # 28

    Steve, more information emerging about possible connection between Arctic ice meltback and climate impacts in southern latitudes of NA.

    On the CH4 issue, (warning, I am not a scientist) OH radical is a CH4 sink and the OH radical acts as an atmosphere cleaning agent. The more CH4, the less OH available to react with other pollutants.

    From Wiki:

    OH + CH4 > H2O + CH3

    The most important sink in the methane cycle is reaction with the hydroxyl radical, which is produced photochemically in the atmosphere. Production of this radical is not fully understood and has a large effect on atmospheric concentrations. This uncertainty is exemplified by observations that have shown between the year 2000 and 2006 increases in atmospheric concentration of methane ceased without reduction in anthropogenic sources, showing that methane accounting does not accurately predict methane observations.

    OH is often referred to as the “detergent” of the troposphere because it reacts with many pollutants, often acting as the first step to their removal. It also has an important role in eliminating some greenhouse gases like methane and ozone.[1] The rate of reaction with the hydroxyl radical often determines how long many pollutants last in the atmosphere, if they do not undergo photolysis or are rained out. For instance methane, which reacts relatively slowly with hydroxyl radical has an average lifetime of >5 years and many CFCs have lifetimes of 50+ years.

    IMO, if more OH is not available because of accelerated reactions with CH4, other pollutants (including GHGs) can increase. In a parallel way,it is as if less plankton in the oceans due to acidification may lead to less CO2 sink.

    FYI…best I can do at this moment. Got any interest or comments?

    John McCormick

  36. Colorado Bob says:

    Stenphen @ 38

    I’ll throw up a page at NewsVine listing each and every bleaching event.
    This freaked out the coral people. They all sound shocked, the global scale is sinking in on this.

  37. John (#39) suggested a reaction for limiting CH4 in the atmosphere 9with a rider that he isn’t a scientist).

    The only problem with this reaction is that it is still unbalanced.

    OH should be OH- (negatively charged) and when it reacts with CH4 (neutral) the methyl group (CH3) produced then has that same negative charge.

    However, to form OH- you split H2O leaving H+, which combines back with the CH3- to make – surprise, surprise – CH4.

    Net outcome – no change… :(



  38. Ricky Ward says:

    About methane release from the permafrost. I wonder if anyone has come up with the idea of covering the area with plastic sheeting and harvesting the methane for fuel as is done on land fill sites?

  39. Michael says:

    Re: La Nina and temperatures

    It is important to remember than there is a lag between ENSO and global temperatures; if you look back at the last La Nina, most of the cooling occurred between December 2007 and January 2008 (GISS); 2007 also had warming between September and October:

    September 2007: 0.50
    October 2007: 0.54
    November 2007: 0.47
    December 2007: 0.40
    January 2008: 0.17

    Also, recent temperature anomalies across much of the Northern Hemisphere are astonishing; the following map shows widespread anomalies (for the last 7 days) in excess of 7 degrees C (off the top of the scale) pretty much everywhere; almost all of Asia as most of North America:

    It only shows latitudes below 60 N/S, but I’m pretty sure the Arctic is just as warm, pretty warm elsewhere too. This certainly seems to suggest that something unusual is going on; on the other hand, I have noticed that land temperatures seem to lag ENSO more than overall global temperatures; for example, 2009 was relatively cool over many land areas, including the U.S., which didn’t really warm until March or April this year.

    [JR: Thanks. I added this to the post.]

  40. David Lewis says:

    Keep in mind that more than 93% of the heat coming into the planetary system has been absorbed by the oceans.

    What everyone tends to focus on in the discussions like those here above is the average global surface temperature record, i.e. the layer of the atmosphere just next to the surface of the Earth. A tiny bit of heat moving around in the ocean, such as El Nino/La Nina ENSO events, has a big impact on this surface temperature record, because a tiny bit of ocean heat relative to the ocean is a large amount of heat relative to the atmosphere.

    ENSO is only the most studied area where ocean heat is moving around. The TAO system sending data about it has been in place since 1994 I think. So when El Nino is in town, the knowledgeable look at the average global surface temperature record and know that its about to go on an upward trend for a while.

    The ARGO system is now very fully deployed and is sending data back about heat from almost all of the global ocean from the surface down to 2000m.

    When a situation happens such as what appears to be happening now, i.e. when supposedly La Nina should be causing some movement of the average global surface temperature chart downward and it isn’t, don’t think its some mystery, or that it means the end is here, or that it is what has been called “natural variability”.

    The odds are it is almost certainly that if the average global surface temperature chart is behaving strangely it is due to the movement of heat somewhere in the global ocean, just because that is where the heat is. And we’re likely to be finding out exactly where soon.

    Dr. Kevin Trenberth a lead IPCC author the last three reports on the science assessment side, in an article in Nature “The Ocean is Warming, Isn’t It?” argues that “revolutionary progress… has taken place in ocean observations….” He predicts that “…ocean heat content is likely to become a key indicator of climate change”. Which is as it should be – keeping in mind that’s where 93% of the new heat that has arrived in the planetary system since industrial civilization started adding GHG to the atmosphere is.

    NOAA has some good graphics putting what’s happening in the global ocean into perspective in a short brochure “State of the Climate 2009, Report at a Glance.

    This surface air temperatures show very warm anomalies widespread over the Northern Hemisphere and Antarctica the last 7 days:

    And it is not a temporary spike. The 30-day anomalies show the same warming pattern:

    If this pattern persist for another month 2010 will certainly break the record for the warmest year.
