Global Temperature Trend Update: September 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 September, 2012.

Global climate trend since Nov. 16, 1978: +0.14 C per decade

September temperatures (preliminary)

Global composite temp.: +0.34 C (about 0.61 degrees Fahrenheit) above 30-year average for September.

Northern Hemisphere: +0.35 C (about 0.63 degrees Fahrenheit) above 30-year average for September.

Southern Hemisphere: +0.33 C (about 0.59 degrees Fahrenheit) above 30-year average for September.

Tropics: +0.15 C (about 0.22 degrees Fahrenheit) above 30-year average for September.

Notes on data released:

September 2012 was the third warmest September in the 34-year satellite temperature record, 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. Three of the last four Septembers were warmer than September 1998, during the El Niño Pacific Ocean warming event “of the century.” The last September that was cooler than the 30-year baseline seasonal norm was in 2000.

Compared to seasonal norms, the coldest spot on the globe in September was (again) at the South Pole, where the Antarctic spring temperature averaged 3.31 C (almost 6 degrees Fahrenheit) colder than normal. The “warmest” spot was just north of Monbetsu, Japan, where temperatures in September averaged 3.72 C (about 6.7 degrees Fahrenheit) warmer than seasonal norms.

    THOSE NUMBERS ARE COOKED!

  • benji||

    You're causing CO2 emissions.

  • Whiterun Guard||

    Cooked by AGW you mean.

  • Ken Shultz||

    I blame Paul Ryan!

  • The Late P Brooks||

    It snowed here last week. Obviously, the new ice age has begun.

  • ||

    Seattle had an amazing Indian summer. This means...nothing. Except an amazing Indian summer. Which is now over, unfortunately.

  • ||

    Racist!

  • ||

    Indian summer means warm weather after a frost, you unlettered prick. How do you not know this? You're too stupid to live.

  • R C Dean||

    What a bunch of racist goons blowing on their dogwhistles.

    "Indian" summer? Really?

    Indigenous-American Summer, please.

  • ||

    Fine, fine. Injun summer. Christ. Why are you so picky about the nomenclature?

  • Whiterun Guard||

    Dogwhistle, eh?

    Just because she doesn't conform to your Rapist-American view of beauty you have to denigrate them with epithets.

    Sexist bastard.

  • ||

    Hmm, has the erstwhile Albino Aboriginal weighed in on this?

  • ||

    I meant an Indian-from-India summer, you fucking racist shitholes (you know, the AIIGGHIIIAAAA Indians, not the HEY-YA-HEY-YA ones). It's a summer with mango chutney. Fuck, you are all idiots.

  • R C Dean||

    Dot, not feather?

    My apologies. Carry on.

  • BarryD||

    Push start or pull start?

  • Ayn Random Variation||

    I blame the extra large farts due to the obesity epidemic.

    As such, I propose a Bloomberg/Michelle O. ticket.

  • Whiterun Guard||

    With his looks and her money that could go places!

  • JW||

    Is that a downward trend in a naturally occurring variable cycle I spy?

  • The Derider||

    The naturally occurring variable cycle is only part of the story.

    Look at the minimum in 1986 and the maximum in 2009. The cycle isn't flat, it's rising over time.

    The link to the satellite data is broken.

  • OldMexican||

    Flo-bot is broken.

  • Ron Bailey||

    JP: Fixed now. Thanks.

  • OldMexican||

    September 2012 was the third warmest September in the 34-year satellite temperature record, 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.

    Yes, we had some badly-needed rains here in Texas. Maybe Climate Change? But since weather is not climate... except when it is, unless it's not... But, then again...

  • BarryD||

    So temperatures remain essentially unchanged in 15 years, but if you look at 34 years, they are rising steadily...

    That suggests, of course, that a 34-year record doesn't tell us much about true long-term trends.

  • Auric Demonocles||

    Basically all the rise happens between 97 and 02. On either side of that span it's just oscillating around a mean (a different mean for each side).

  • ||

    If you'd like to look at a longer trend, look at the HadCRUT data.

  • BarryD||

    1850-present is not very long, either, nor can the data from satellites and surface instruments be compared, really, when you're talking about the levels of accuracy in these numbers.

  • The Late P Brooks||

    The propane guy was just here; price is down about $.25/gal compared to last year. I do not believe this is related to the money supply.

  • The Late P Brooks||

    I meant an Indian-from-India summer

    Jesus.

    It's "Hindoo Indian, or Woo-Woo Indian"

    Get your Pythons in a row, grunge-boy.
