The 12-month period from December 2009 through November 2010 was the warmest on record globally, according to NASA's Goddard Institute for Space Studies. The average land and ocean combined temperature anomaly for the period was .65 Celsius or 1.17 F above the 1951-1980 global mean, beating the previous warmest 12-month period of +.62 Celsius during 2005. Third place is currently held by 2007 with a reading of +.61 Celsius. The maps below show the northern and southern hemispheric temperature anomalies for the Dec 2009 to Nov 2010 period. Red areas show the warmest regions relative to normal. The GISS regional temperature anomaly graph below shows that most of the warming over the past century has occurred over the far northern latitudes.

Don't you have any real data from crackpot blogs like no gnu taxes has?
Thank you. And all you deniers. Not to worry. Nothing will be done. 8D This content is temporarily unavailable Please try again shortly http://video.foxnews.com/v/4469522/hannity/
LoL! I actually thought about posting the same charts that Eric posted and seeing if he rants against them.
LMAO. Excerpts from an article published in the Hawaii Reporter on 9/21/2010 BY JACK DINI “There are some other issues that cloud the temperature data from the Arctic. They include an expanded definition of ‘Arctic,’ extrapolations rather than accurate temperature measurements, and the simple fact that the Arctic has been warmer in previous times. First, let’s look at the expanded definition of ‘Arctic.’ If you headed south from the Arctic toward the equator would you expect the weather to change? Well, you don’t have to be smarter than a fifth grader to know that the further you got away from the Arctic Circle the more likely the weather wouldn’t be as severe. One unreported fact about the Arctic is that its geographical boundaries have been expanded. Several years ago the Arctic Climate Impact Assessment (ACIA) decided to expand the Arctic by about 50% or approximately 4 million square miles. (2) Have you seen or heard about this from the media? What about temperature extrapolations? James Hansen of NASA, an ardent believer in man-made warming announced recently that “The 12-month running mean global temperature in the Goddard Space Institute (GISS) analysis has reached a new record in 2010. The main factor is our estimated temperature change for the Arctic region.” The GISS figures show that recent temperatures in the Arctic have been up to four degrees C warmer than in the long-term mean. Yet, as Dennis Avery reports, “Here’s what Hansen doesn’t report. GISS has no thermometers in the Arctic. It has hardly any thermometers that are even near the Arctic Circle. How do they determine the temperature? GISS estimates its Arctic temperatures from land-based thermometers that each supposedly represents the temperatures over 1200 square kilometers.” (3) Art Horn observes, “You must be asking how can GISS show any temperature readings at all north of eighty degrees if they don’t have any data? The answer is simple, they make it up. In broadcasting there is an old saying that says, “Why let the truth stand in the way of a good story.” Apparently GISS and NOAA have borrowed that storyline to make the case that the world is warming dangerously due to the way we make energy.” (4)” http://www.hawaiireporter.com/questionin… The bogus interpolation of Arctic temperature data by NASA-GISS is one of the main reasons GISTEMP shows more warming than HadCRUT3, even though they both rely on the same basic station data. NASA-GISS use a cooler baseline for calculating their anomaly; so GISTEMP should run a little hotter than HadCRUT3. But the offset shouldn't be dynamic. It should be static. But it's not. If you subtract HadCRUT3 from GISTEMP, you'll find that GISTEMP has "warmed" 0.1°C relative to HadCRUT3 since 1998... http://i90.photobucket.com/albums/k247/d… This is why the Warmistas always refer to the GISS data. It's the only one that shows any warming since 1998. Another funny thing. During the early 20th century warming, GISTEMP shows ~0.1° C of cooling relative to HadCRUT3... http://i90.photobucket.com/albums/k247/d… Hansen & gang have been slowly smoothing the early century warming and mid century cooling out of GISTEMP... Probably because those things are just as inconvenient to them as the Medieval Warm Period & Little Ice Age were inconvenient to Mann & the hockey team. I can understand a temperature series changing as new observations are added. But it appears that GISTEMP is changing in the past. The 1930's appear to have cooled since 1999... Getting tired of the bozoed calcon following me around on the 'net, wanting to discuss "tossing salad." Sorry, you sick rump-ranger. NOT interested.
