On January 16, 2008, Dr. James Hansen of NASA’s Goddard Institute for Space Sciences (GISS) released the summation of temperature data for 2007 with apparently very little fanfare. Given the data collected by Dr. Hansen, the lack of fanfare itself might well be notable. But regardless, the data itself bears more public attention that it’s had.
2007 is now tied with 1998 as the second hottest year for global temperature in a century.
According to the the GISS 2007 summation press release online, all eight of the hottest years for global temperature have been since 1998, and 14 of the hottest years have been since 1990. The global temperature map (shown in image above - larger version available), the Arctic and Siberia had the greatest temperature increase, between 3 and 4 degrees Celsius. This heating was responsible for, or a direct result of, the smallest Arctic ice cap since records have been kept. ...

Given that James Hansen is claiming that 2007 is the warmest year in a century, he ought to check with claims made by the National Oceanic and Atmospheiric Administration which maintains that the winter of 2007-2008 was the coldest since 2001. It was so cold the winter icepack not only grew back to its formal winter size, it also got up to 22cm thicker. No polar bears went extinct this winter due to lack of ice. But elsewhere on this supposedly hottest-year-ever planet, billions Chinese were buried under an ice storm that lasted several weeks. Record cold temperatures were seen in cities which have has never even seen snow before.
One fine point, before you write again that the higher global temperatures in 2007 were (1)responsible for the larger than normal summer ice melt or (2) it was the ice melt that "caused" the higher than normal temperatures. you really ought to get your story straight and pick one cause or the other, not offer the reader the choice of two mutually contradictory ones.
Hello. This post is likeable, and your blog is very interesting, congratulations :-). I will add in my blogroll =). If possible gives a last there on my blog, it is about the Notebook, I hope you enjoy. The address is http://notebooks-brasil.blogspot.com. A hug.
