All Antarctica Now Warming
http://dsc.discovery.com/news/2009/01/21/antarctica-warming.html
It has been claimed that parts of Antarctica were cooling, and that
posed a serious threat to the "theory" of global warming. No longer.
"...a common belief is that the icy slabs have even cooled slightly
and possibly thickened, partly in response to the chilling seasonal
effects of the ozone hole over the South Pole.
Not so, the new study says.
It calculates that West Antarctica has been warming by 0.3 degrees
Fahrenheit per decade over the past 50 years.
This is even more than the Peninsula, where the average rise is
estimated as 0.2 F per decade.
There has indeed been some cooling in East Antarctica, but this was
mainly in the autumn, and occurred as a result of the ozone hole.
There was also a period of strong cooling between 1970 and 2000.
But, overall and when calculated over 50 years, East Antarctica has
warmed too -- by an average of 0.18 degrees Fahrenheit per decade, a
figure that the authors describe as "significant.""
