The climate change-global warming crowd is having a bad couple months. A math error was found in the algorithm that predicted catastrophic climate change. Once it was fixed, the data didn’t show any such thing. Climate skeptics are firing back at the proponents. And one study after another seems to be demonstrating that fluctuations in carbon dioxide and sea ice are a natural phenomenon.
Take the NASA study published in the Journal of Glaciology that says thanks to snow accumulation on Antarctica’s glaciers which has been accumulating for, oh, 10,000 years, the net gain in glacier ice outdistances the losses of sea ice by a whole lot.
The extra snowfall that began 10,000 years ago [after the last ice age] has been slowly accumulating on the ice sheet and compacting into solid ice over millennia, thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year. This small thickening, sustained over thousands of years and spread over the vast expanse of these sectors of Antarctica, corresponds to a very large gain of ice – enough to outweigh the losses from fast-flowing glaciers in other parts of the continent and reduce global sea level rise.
Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.
Zwally is Jay Zwally the climate “scientist” who proclaimed a bit prematurely that the ARCTIC was in big trouble. We all know how accurate that was. Now Zwally is reporting that while the sea ice on Antarctica MIGHT be retreating, it’s being made up by snowfall at a 3:1 ratio. Billions of tons of ice are added to the glaciers in Antarctica every year. BUT, BUT, BUT – we can’t get complacent.
In a piece at Nature News, Zwally has said:
“Parts of Antarctica are losing mass faster than before,” says Jay Zwally, a glaciologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of a paper to appear in theJournal of Glaciology1. “But large parts have been gaining mass, and they’ve been doing that for a very long time.”
The findings do not mean that Antarctica is not in trouble, Zwally notes.
“I know some of the climate deniers will jump on this, and say this means we don’t have to worry as much as some people have been making out,” he says. “It should not take away from the concern about climate warming.” As global temperatures rise, Antarctica is expected to contribute more to sea-level rise, though when exactly that effect will kick in, and to what extent, remains unclear.
Of course it does. In the meantime, the skeptics and deniers are just going to sit back and watch the real data roll in. Every time a new study comes out they seem to be vindicated.
