Helen Dyer forwards this:

The NY Times report is based on the two other studies and the whole apocalyptic report is based on a presumption that the global temperatures are going to rise catastrophically because of human burning of fossil fuels

There’s just a minor problem with all of this. None of these so called studies made any proof whatsoever on how the temperatures were going to rise. The article is based on a presumption the temperatures are going to rise. Their presumptions are based on the IPCC’s failed computer models showing carbon will cause warming.

I’ve just recently read that one of those IPCC models was written by a 17 year old student in Canada who is now standing for the greens in some upcoming Canadian elections.

The story focuses on West Antarctica where there is some melting. They don’t mention East Antarctica is freezing over having recently recorded record sea ice thicknesses. This is all consistent with the earth’s tilt and precession cycles. As the earth tilt changes, the polar ice caps have to move accordingly. It also fails to mention the NASA reports showing the Antarctic ice cap has been growing for 20 years and doesn’t mention Antarctic temperatures have been falling for 100 years.

The NY Times article refers to the study "Study Predicts Antarctica Ice Melt if All Fossil Fuels Are Burned”. This study refers to the subsequent study "Combustion of available fossil fuel resources sufficient to eliminate the Antarctic Ice Sheet”. This so called study states that CO2 residence time in the atmosphere is 10,000 years. That contradicts the attached recent study from the real scientists "Scrutinizing the carbon cycle and CO2 residence time in the atmosphere”. This states CO2 residence time in the atmosphere is 4 years and only 15% of all carbon in the atmosphere is from humans. The rest is natural. And since Carbon is only a very minor greenhouse gas, it is almost impossible that human emissions can have any effect on global temperatures.

So it’s all a great big catastrophic story about nothing.

A NOTE FROM TIM:

There is active volcanism under the West Antarctic ice sheet, which also helps explain why the WAIS loses ice while the East sheet is growing. If Global Warming were causing the ice to melt it would not calve in this fashion, but rather would melt away. It's warming from the bottom. Now, much of the WAIS floats over the sea, but what does that mean? Antarctic waters are cooling, not warming, and the sea ice has been growing. Oh, the Gang green will argue the depths are heating and this is why the ice sheet is collapsing, but this is illogical; the Antarctic circumpolar current is a cold current that completely encircles the Antarctic, and it is a wide and deep current which prevents warm water from reaching the continent; it's why Antarctica is so cold, much colder than the Arctic, which benefits from some warm water entry.

The East Antarctic ice Sheet also lies on top of bedrock at a higher elevation while the West sheet is over lower land and in fact floats on top fo the ocean in large sections. The result is the larger, heavier East sheet puts pressure on the West sheet and forces it down into the ocean, where, after floating for a while, increasing pressure from above breaks off segments. It's much like a woman's fingernail breaking because she let it grow too long. Growth in the East sheet means more calving in the West. In short, the West sheet breaks more often when there is more ice, not less.

Bear in mind Antarctica remains below freezing the entire year; at McMurdo Station, a warm area on the coast, summertime averages are 26* F. and winter is -15. The interior gets much colder; -76* mean yearly temperature. It is far, far too cold in Antarctica to think ice shelf collapse is caused by warming air from a rise of perhaps 2 molecules of carbon dioxide per ten thousand molecules of air. (There are between three and four molecules of carbon dioxide in every ten thousand molecules of air - a trace gas, and only a fraction of that is caused by industrial emissions.) Do we really believe that ice sheet collapse is caused by THAT?
