A new NOAA preliminary report (State of the Climate Global Analysis January 2010) indicates January 2010 was one of the warmest on record. Surely, this will convince AGW deniers they were wrong to argue the mid-Atlanctic snowstorms are evidence global warming has ended. Hat tip to Joe Romm, see his coverage here.
Speaking of the DC snowstorms, I love this quote by Dana Milbank “As a scientific proposition, claiming that heavy snow in the mid-Atlantic debunks global warming theory is about as valid as claiming that the existence of John Edwards debunks the theory of evolution.”
From the NOAA report
The combined global land and ocean average surface temperature for January 2010 was 0.60°C (1.08°F) above the 20th century average of 12.0°C (53.6°F). This is the fourth warmest January on record. The global land surface temperature for January 2010 was 0.83°C (1.49°F) above the 20th century average of 2.8°C (37.0°F)—the twelfth warmest January on record. Land areas in the Southern Hemisphere were the warmest on record for January. In the Northern Hemisphere, which has much more land, comparatively, land surface temperatures were 18thwarmest on record. The worldwide ocean surface temperature for January 2010 was the second warmest—behind 1998—on record for January, 0.52°C (0.94°F) above the 20th century average of 15.8°C (60.5°F). This can be partially attributed to the persistence of El Niño across the equatorial Pacific Ocean. According to NOAA’s Climate Prediction Center (CPC), El Niño is expected to continue through the Northern Hemisphere spring 2010.
It really doesn’t look like this has been a cold winter globally or that the earth is cooling does it:
The January 2010 average temperature for the Southern Hemisphere as a whole (land and ocean combined) was 0.58°C (1.04°F) above the 20th century average—the second warmest January on record, behind 1998. However, the Southern Hemisphere land temperature was the warmest on record, surpassing the previous record set in 2006 by 0.02°C (0.04°F).
The global ocean temperature represented the second warmest January on record, with an anomaly of 0.52°C (0.94°F) above the 20th century average—the second warmest January, behind 1998.
Perhaps these are the facts Andrew Bolt was alluding to here?
Measured temperatures for the lower troposphere are the highest ever recorded (NOAA; “Global averages from radiosonde data are available from 1958 to present, while satellite measurements date back to 1979”)
Although most of the Arctic Ocean experienced cooler-than-average temperatures, the Arctic sea ice extent remained below average.According to the National Snow and Ice Data Center (NSIDC), the January 2010 Northern Hemisphere sea ice extent—which is measured from passive microwave instruments onboard NOAA satellites—was 13.8 million square kilometers (7.2 percent or 1.1 million square kilometers below the 1979–2000 average), resulting in the fourth lowest January sea ice extent since records began in 1979.
