Global Temperature Trend Update: March 2012

|

Every month University of Alabama in Huntsville climatologists John Christy and Roy Spencer report the latest global temperature trends from satellite data. Below are the newest data updated through March, 2012. 

Global Temperature Trend March 2012

U.S. Hits Record Highs in March: Iowa is the "warmest" place on Earth

Global climate trend since Nov. 16, 1978: +0.13 C per decade


March temperatures (preliminary) baseline: 30-year average for the month

Global composite temp.: +0.11 C (about 0.20 degrees Fahrenheit) 

Northern Hemisphere: +0.13 C (about 0.23 degrees Fahrenheit) 

Southern Hemisphere: +0.09 C (about 0.16 degrees Fahrenheit) 

Tropics: -0.11 C (about 0.20 degrees Fahrenheit) 


February temperatures (revised):

Global Composite: -0.11 C below 30-year average

Northern Hemisphere: -0.01 C below 30-year average

Southern Hemisphere: -0.21 C below 30-year average

Tropics: -0.28 C below 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Did you experience an unusually warm March? The UAH press release explains that you were not alone if you live in the lower 48 states:

Compared to seasonal norms, March 2012 was the warmest month on record in the 48 contiguous U.S. states, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. Temperatures over the U.S. averaged 2.82 C (almost 5.1° Fahrenheit) warmer than normal in March.

The previous U.S. record warm anomaly in the 33-year satellite temperature record was in November 1999, when temperatures over the U.S. averaged 2.22 C (about 4° F) warmer than the seasonal norm for November. The next warmest March was in 2007, when temperatures over the U.S. were 2.0 C (about 3.2° F) warmer than normal.

While the long-term climate trend over the U.S. has seen warming at the rate of about 0.21 C (almost 0.38° F) per decade during the past one third of a century, March's temperature anomaly is just that: an anomaly, Christy said. "We see hot and cold spots over the globe every month, and this was just our turn. A one-time anomaly like this is related to weather rather than climate. Weather systems aligned in March in a way that changed normal circulation patterns and brought more warm air than usual to the continental U.S."

In fact, the warmest spot on the globe in March (compared to seasonal norms) was northeastern Iowa, where temperatures for the month averaged 6.20 C (about 11.2° F) warmer than normal.

By comparison, the winter (DJF) of 2011-2012 averaged 0.94 C (about 1.7° F) warmer than seasonal norms for the continental U.S.

In recent years March has not typically seen temperature extremes over the U.S. The March 2011 temperature for the "lower 48" was at the seasonal norm.

The coolest spot on Earth in March 2012 was northwestern Alaska, where temperatures averaged 3.89 C (7.0° F) colder than normal.

  1. fsrit!

    1. Somehow I read that as “frost.”

      1. Frost has been done already.

  2. Global temperature trend update: still within the normal variation, as it has been for the past 50 years, while we were alternately warned about an impending ice age, global warming, or now the “not ready to place any money on this bet” version, global climate change.

  3. Every month University of Alabama in Huntsville climatologists John Christy and Roy Spencer report the latest global temperature trends from satellite data

    And every month this means Jack and shit, and Jack left town.

    1. It’s a bit more important than that.

      Unlike surface temperature records which have many potential sources of error and bias, the satellite data provide a more reliable proxy of the planet’s temperature, for a variety of reasons, but mostly because satellites should be immune from Urban Heat Island distortions.

      Christy and Spencer’s UAH data record has shown that while the earth has warmed over the last 3+ decades, the rate of global warming has been less than the alarmists have projected, and also less than what’s being reported in the surface temperature data series (namely GISTEMP & HADCRUT3).

      1. Yeah, 30 year time span?

        No, it’s not important. It’s masturbation for environmentalists.

        1. Half a human lifetime is not important? It’s not enough to conclude anything about the climate or what we can expect over the long term. And the data from these guys hardly supports the extreme alarmist positions. More like masturbation for H&R commenters.

          People should certainly be more honest about how limited knowledge is on this subject, but that doesn’t mean that no legitimate comment can be made about it, or that it is completely useless.

      2. So, did any of the global warming model predict, or can any of them account for, the decade-plus plateau that we seem to be in?

        1. nope.

      3. the satellite data provide a more reliable proxy of the planet’s temperature, for a variety of reasons, but mostly because satellites should be immune from Urban Heat Island distortions.

        [citation please]

        And while they may be immune from “urban Heat Island Distortions,” they are far from immune to tampering, adjusting and flat-out manipulation to coincide with predetermined theories.

        The only reliable data is real data. Not some computer simulated temperature data derived from satellites 20 miles above the earth. And the real data is too young to be reliably counted on. Therefore, we need at least a century more real data before any conclusions can be drawn.

  4. Global warming is so obviously real! Just look at Dallas yesterday! That would never happen if AL Gore weren’t right. n And it will happen more and more and more until we’re all deeeeaaadddddddd!

    Doom! DOOM! DOOOOOOOOOOOOOOOOM!

    1. We must all work together to stop manbearpig. I’m super serial.

    2. That would never happen if AL Gore weren’t right.

      More to the point, those tornadoes would never have occurred if the Supreme Court hadn’t stolen the election from him.

    3. That is a very similar argument a friend made last night. Verbatim, he said “We’re in a lot of trouble if climate change is causing tornadoes to hit cities.”

      1. The tornados contend that the cities were hitting them.

  5. OT: I love working in an industry where the admins write Ayn Rand quotes on their whiteboards before going on vacation.

    1. “I am leaving it as I found it. Take over. It’s yours”?

    2. I shrugged 5 years ago.

      I’ve made lots of good decisions in my life but that was the best.

  6. Judging by that chart we’ll need to be worrying about global cooling sometime around 2021. That sound about right?

    1. No, because at first the drop in global temperatures will be dismissed by TEAM HOT as isolated incidents. It won’t be until global temperatures decline for about 5 years that they make anything about it, and even then it will be hailed as the result of Carbon-limiting legislation bringing us back to around Gaia’s intended temperature.

      Then, around 10 years into the cooling trend we’ll hear the cries of a new Ice Age that will destroy the earth. Naturally, mankind will be to blame.

      1. Even if it starts cooling they will still claim that it is warming.
        The science is irrefutable!
        There is a consensus!
        A consensus I tell you!
        A consensus!

      2. But TEAM CHILL and TEAM NIL just doesn’t have the same cache as TEAM HOT and TEAM NOT.

      3. At some point we are going to get another big volcanic erruption somewhere. It has got to happen sometime right? And when that happens team hot will be off the hook. They will say “of course none of our predictions turned out, we had that volcano that saved us”.

        1. That’s just how I roll.

      4. Haven’t some already started to say “no, we meant climate instability instead?” Sure you did.

  7. Climate Change: Yes, it does!

  8. Architects’ answer to rising seas: floating homes

    Around the world architects and city planners are exploring ways mankind and water may be able to coexist as oceans rise and other phenomenon induced by climate change, including extreme, erratic floods, threaten land-rooted living.

    “We will have to live with a more watery environment. There is no choice,” says Danai Thaitakoo, a Thai landscape architect whose own Bangkok house was swamped last year as the country suffered its worst floods of modern times.

    The Thai capital is also among the mega coastal cities projected by the end of this century to lie totally or partially under water as global warming boosts sea levels, according to the U.N. Intergovernmental Panel on Climate Change. Others include Tokyo, London, Jakarta, Sydney and Shanghai ? an apocalyptic prospect of mass migrations and economic crises.

    PLEASE update ur dist list cancelling climate change. The list keeps getting longer about those who werent notified.

    1. It worked for Mariner and Deacon.

    2. Underwater cities are way cooler.

      1. et tu atlantis?

        1. I think the real answer we need is which half of the merfolk are fish, upper or lower?

          1. “Oh, why couldn’t she be the other kind of mermaid, with the fish part on the top and the lady part on the bottom?”

            1. It’s all chum inside.

              1. Leela: Fry, are you all right?

                Amy: What about Umbriel?

                Fry: Well, it turns out I loved her, but I wasn’t in love with her.

                Amy: (whispers) Trouble in bed.

                1. Ugh. Why do I have to keep reminding you of the best quote from that one?

                  Leela: “Five thousand feet!”
                  Farnsworth: “Dear Lord! That’s over one hundred and fifty atmospheres of pressure.”
                  Fry: “How many atmospheres can the ship withstand?”
                  Farnsworth: “Well, it’s a space ship. So I’d say anywhere between zero and one.”

    3. So basically I’m going to be designing house boats.

      You know, I don’t oppose that, could be kinda fun. As long as I’m not forced to do it.

    4. Seeing as my next home will be at about 6300 feet above sea level, I think I’ll pass on floating functionality.

      If the sea level gets that high, I figure I’ll have bigger fish to fry.

      1. literally & figuratively

  9. So I am banned at home, but not at work. How sad.

  10. Enjoyed the very warm two weeks in March here in the mitten. Not so much the plant killing freezes and snow since then.

  11. A one-time anomaly like this is related to weather rather than climate.

    This is the kind of crap that bugs me. Weather is the physical manifestation of climate. Weather defines climate and vise/versa.

  12. Weren’t they predicting in the 90s, that Florida would be under 3 feet of water by now?

    How long must we wait for the disaster?

    1. To be fair, most of Florida is underwater. Just ask your realtor.

      1. Sell yourself short.

  13. I like these posts, they tell me…

    shit. They tell me shit. I know you feel like you’re doing your good deed of the month whenever you post this, placating the environmentalists with a statement of “See, I’m paying attention!”, but they tell me shit.

    1. To sum it up, we’re measuring global temperatures better now, so that in 150 years we can better discern whether we’re fucked now or not at all.

  14. Warnings about our uncertain food future may call to mind the false predictions of Thomas Malthus and Paul R. Erlich, who warned, centuries apart, about food crises that never came to fruition. But the reality is that we now face three major threats to the world food supply. Climate change will require a restructuring of our agricultural systems. A population boom?United Nations projects that the Earth will host 9 billion souls by 2050?means more mouths to feed than ever before. And thanks to new wealth in countries like China and India, an increasing number of people will demand a new diet heavy on meat and other foods that require plentiful resources.


    “I’ll name-check these fear-mongers as false before indulging in my own fear-mongering that is exactly like the fear-mongering they engaged in.”

    1. So wait, are you saying that retarded people write for Slate?!? When did this happen?

      1. Its readers are retarded. So it kind of makes sense they would hire writers who could speak to them doesn’t it?

        1. Chicken and egg, John. Does Slate have retard writers because its readers are retards, or does it have retard readers because its writers are retards?

          RIDDLE ME THAT BAT-MORON

          1. Since it is a spawn of the Washington Post, I think the readers came first. The Post wanted to set up a special site for its most retarded readers by getting rid of a good sports page, the classifieds and anything else that rational readers of the Post might like. They wanted to go full and pure retard on Slate. And they succeeded.

          2. Since it is a spawn of the Washington Post, I think the readers came first. The Post wanted to set up a special site for its most retarded readers by getting rid of a good sports page, the classifieds and anything else that rational readers of the Post might like. They wanted to go full and pure retard on Slate. And they succeeded.

            1. NEVER go full retard!

          3. Neither, it has both because a lot of companies like to market to morons, and someone saw the niche to create an advertising vehicle for.

            The market wins again.

            1. No one ever went broke because they tried too hard to cater to morons.

              1. Are you sure about that?

                I don’t think the Post or Slate are doing particularly well financially.

                Of course Matt and Nick i think have said political opinion journalism regardless of slant has never been a good money maker…

                This is not true in reality…Rush makes money…but his existence and his ability make cash is only possible because he is an alternative to MSM statist leaning regular news.

                If ABC, NYT, the post, npr were not such apologists for an over bearing state Rush would cease to exist….and the world of opinion journalism would follow Matt’s and Nick’s claim.

          4. Aren’t Slate readers and writers absolute geniuses in comparison to Kos and DU? Sad to say but I don’t think Slate really touches the bottom of the left barrel.

            1. That is a scarier thought than the hairy T-Rex in the link below.

            2. Even the top of the barrel for those idgits is pretty moronic. I just heard a Van Jones interview on Democracy Now! (one of the higher-brow lefty shows) and he was talking about how the problem with race is that we don’t talk enough about it. He also said that he felt a pang of fear the other day when he realized he was wearing a hoodie (i guess someone else dressed him).

      2. I know. I was shocked as well.

        1. Once in a while I will get a masochistic streak and go comment there. Tony and Orin are geniuses compared to the people on there. They are completely irrational and misinformed. But make up for it by being smug and hostile.

          1. Slate aint all bad. They have some Deadspin stuff on sports that is decent. I guess that is not straight up slate… The XX blog is entertaining in its way.

            Plus Slate is a fun place to be the libertarian troll, as they see it. RON PAUL ANARCHIST!

            1. I troll the shit out of them. What is fun is you don’t even have to be a libertarian or even a Republican to do it. You just have to ask them to give a rational argument for their positions and point out that ad homonym and emotion are not rational arguments. It drives them nuts.

              I trolled them an abortion thread one time by just asking “why do you think life begins at birth and not before that?”. They went berserk. I was changing the subject. This was about gender issues and coercion. Life had nothing to do with it and I was just a anti-choice bigot. You couldn’t make people up like that.

              1. ad homonym

                Yeah, to hell with adding.

            2. And Dear Prudence is great. And some of their sports stuff is alright.

            3. Slate is still the place that looked at the accumulated work of Matt Yglesias and said to themselves: We need to give this guy a job.

              1. Slate is still the place that looked at the accumulated work of Matt Yglesias and said to themselves: We need to give this guy a job.

                They fired Michael Kinsley, who is an actual really smart guy, and later hired Yglesias. The drop in IQ from that one trade alone is just staggering.

          2. They are completely irrational and misinformed. But make up for it by being smug and hostile.

            Isn’t that the essence of liberalism?

    2. “But this time it is different.” Always.

    3. its a nice trick, followed by assumptions that the worst of climate change fears are factual and coming.

      The nouveau riche in China and India won’t be having 2.3 babies either. Plus they don’t have enough women as it is now.

      1. the birth rate is dropping all over the place. It is even dropping in places like Iran where you would never expect it to be low.

        1. I wish I could live long enough to see the future utopia brought on by population crash.

          1. Assuming technology advances enough that people can stay productive into their very old age, me too. And who knows maybe the singularity would hit and you might get to see it.

    4. It must be nice to have a job that requires no discernible skill besides the ability to pull stupid shit out of my ass and use big words so that retarded people will think I’m really smart.

      1. Dude, why the hostility towards NutraSweet? Yeah, that’s him to a T, but you didn’t have to phrase it like that.

        1. Leave me out of this.

    5. And thanks to new wealth in countries like China and India, an increasing number of people will demand a new diet heavy on meat and other foods that require plentiful resources.

      I guess it’s a good thing that China is FUCKING HUGE, and that, if used efficiently, it should be more than enough land to grow/raise more than enough food for the Chinese.

      1st worlders who complain about possible food shortages have never stepped outside of a city. Have you ever seen Wyoming or the Dakotas? They’re fucking huge, and much of it is completely unused (mostly because vast swaths of it aren’t owned by private enterprises which have an incentive to put that land to use).

      1. Have you been to Wyoming/Dakotas?

        They aren’t uninhabited because of their wonderful climate.

        You try growing wheat on the high desert of Wyoming.

        But that’s neither here nor there. I agree with your general premise.

  15. “(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)”

    rendering this exercise meaningless.

    1. Gad, this that you? Or his brother Ged?

  16. F-ck you Bailey! Here’s some scary science:
    http://www.msnbc.msn.com/id/46…..e-science/

    Warm, fuzzy Tyrannosaurus theorized.

    1. Will Spielberg channel his inner George Lucas and digitize and re-release Jurassic Park? Or just remake it?

    2. I would have said “hot, hairy Tyrannosaurus”, but whatevs.

    3. I don’t imagine T-rex had much use for camouflage like a leopard or a tiger.

      It could have been brightly colored.

      Giant land roving rainbow jaws of death.

    4. T-rex was a drag queen?

  17. Tiny Tim said the ice caps were melting in 1967… I believe him. We need to do something before it is too late.

  18. Damn. I wish anyone were capable of discussing this in a reasonable way. Why the fuck do people care more about winning than knowing what is actually the case? (And neither side is innocent of this in this debate.)

    1. Zeb translation:

      Damn. I wish anyone were capable of discussing this in a reasonable way. Why the fuck do people care more about winning than knowing what is actually the case?

      Translation: There are extremes on both sides…therefor no one wants to discuss it reasonably.

      (And neither side is innocent of this in this debate.)

      translation: Please ignore my glaring contradictory judgment, and the fact that I have added nothing to the debate but ad hominem in regards to the debaters.

      Also lately it has been hard to fap to my life sized poster of Al Gore

  19. “The coolest spot on Earth in March 2012 was northwestern Alaska, where temperatures averaged 3.89 C (7.0? F) colder than normal”. Well coolest relative to normal. I would like to see the temperatures at the North Pole and Vostok, Antarctica.
