MIT Scientists Confirm Antarctica Is Cooling
By Paul Homewood
Just a little clarification is in order on yesterday’s post Global Warming Causes Cooling In Antarctica ( Or Maybe It’s Just Natural!)
The press release from MIT stated that “However, Antarctica has cooled and has gained some ice recently”.
Reader David correctly points out that the Abstract states:
In recent decades, the Arctic has been warming and sea ice disappearing. By contrast, the Southern Ocean around Antarctica has been (mainly) cooling and sea-ice extent growing.
However, it seems that the original press release had it right. The full paper finds that:
Over the last few decades, the two polar regions of our planet have exhibited strikingly different behaviours, as is evident in observed decadal trends in surface air temperature shown in figure 1. The Arctic has warmed, much more than in the global average, primarily in winter, while Arctic sea-ice extent has decreased dramatically. By contrast, the eastern Antarctic and Antarctic plateau have cooled, primarily in summer, with warming over the Antarctic Peninsula and Patagonia . Moreover, sea-ice extent around Antarctica has modestly increased.
In other words, the authors find that most of the Antarctic continent has cooled, rather than just the Southern Ocean, which is quite an important difference.
What we seem to be left with is a paper that uses computer simulations to find that global warming has managed to cool Antarctica, and lead to an increase in sea ice there. This is despite the fact that, according to the IPCC, the vast majority of models predict the opposite.
Pardon me if I am underwhelmed.
