Global Warming? - #2112 - Climate: New Study Slashes Estimated Ice Cap Loss - Yahoo News

Estimates of the rate of ice loss from Greenland and West Antarctica, one of the most worrying questions in the global warming debate, should be halved, according to Dutch and US scientists.  In the last two years, several teams have estimated Greenland is shedding roughly 230 gigatonnes of ice, or 230 billion tonnes, per year and West Antarctica around 132 gigatonnes annually.  Together, that would account for more than half of the annual three-millimetre (0.2 inch) yearly rise in sea levels, a pace that compares dramatically with 1.8mm (0.07 inches) annually in the early 1960s.  But, according to the new study, published in the September issue of the journal Nature Geoscience, the ice estimates fail to correct for a phenomenon known as glacial isostatic adjustment.  This is the term for the rebounding of Earth's crust following the last Ice Age.  Glaciers that were kilometers (miles) thick smothered Antarctica and most of the northern hemisphere for tens of thousands of years, compressing the elastic crust beneath it with their titanic weight.  When the glaciers started to retreat around 20,000 years ago, the crust started to rebound, and is still doing so.  Read more........  Rush read from this article today on his radio show, to help us keep this global warming fraud in perspective.


Old Farmer's Alamanac:  Global Cooling to Continue - Yahoo News - Most of the country will see a colder-than-usual winter while summer and spring will be relatively cool and dry, according to the time-honored, complex calculations of the "Old Farmer's Almanac."  The 2011 issue of the almanac, which claims to be the nation's oldest continuously published periodical, was released Tuesday. It predicts that in the coming months, the Earth will continue to see a "gradual cooling of the atmosphere ... offset by any warming caused by increased greenhouse gases."  The "Old Farmer's Almanac" also is forecasting a weak La Nina — a climate phenomenon marked by an unusual cooling of the sea surface in the tropical Pacific Ocean.  Janice Stillman, editor of the almanac, said that means much of the eastern half of the United States will experience lower-than-normal temperatures with less snow while Mid-Atlantic states will see more snowfall than usual. The West will see a mild winter with average precipitation, she said.  Read more........  I hate to get my hopes up as I love snow, that just maybe we might return to the winters we had in the 80's.  Maybe not in the amounts of 17-18 inches at a time, but certainly more than the dustings we have experienced in the last 10 years, except for last year.
