The high-profile collapse of some Antarctica's ice shelves is likely the result of natural current fluctuations, not global warming, says a leading British expert on polar climates.
This surprising finding is supported by analysis of data from the European Space Agency's ERS-1 satellite, according to Duncan Wingham, Professor of Climate Physics at University College London.
"But...but...isn't the ice at least thinning? Aren't we losing Antarctic ice?"
Um...no. At least not in the fashion the alarmists are touting.
The data, measuring changes in ice thickness across the Antarctic ice sheet using the polar orbiting satellite, show areas of growth from snowfall are as common as areas of decline.
"Yeah, but you evil deniers are just cherry picking the data. Your making things seems better than they are. Scumbag."
Um...no. Us "evil deniers" aren't the ones cherry picking anything. It seems YOU alarmists are.
This is a contrasting picture to one based solely on the northern Antarctic Peninsula - a shark's fin of land jutting out from the body of the continent, and reaching to just 750 miles from Chile - where there has been a drastic increase in temperature, thinning of ice sheets and collapse of ice shelves. The Larsen A ice shelf, 1600 square kilometres in size, fell off in 1995. The Wilkins ice shelf, 1100 square kilometres, fell off in 1998 and the Larsen B, 13,500 square kilometres, dropped off in 2002. Meanwhile, the northern Antarctic Peninsula's temperatures have soared by six celsius in the last 50 years.
"A lot of attention and research has focused on this relatively accessible area of the Antarctic Peninsula, but satellites are giving us a picture of the continent as a whole," Wingham told the Register. This broader picture shows evidence of growth and decay from place to place, a picture more in line with natural variations in snowfall and ocean circulation. The Antarctic is to some extent insulated from global warming because to its north are zonal flows in the atmosphere and ocean, unimpeded by other landmasses. This insulates the continent from warmer events further north and leads one to suppose it is better protected from global warming.
WHAT?!!!
This is a very reasoned article written apparently by an unbiased individual. It is a great read.
Will someone please smack the Goracle right in the mouth now?
