IT'S GETTING HOT IN HERRE!

Temperatures are sweltering across the nation. It's also warming up in Antartica, where 50 billion tons of ice just melted off of an ice shelf. Global warming is not some phantom in the distant future--it's effects are here NOW! 2 summers ago 35,000 people died of heat-related symptons in Europe. It's clear that this government's corporate ties will never engage them in actively reducing greenhouse gases because it would cost them too much. But how selfish and irresponsible is that? To not care about future generations? And how un-christian!!! How can you thump a bible on one hand and allow God's own earth to be desecrated by man's actions, and do little to stop it until your hand is forced? It's uncaring, Republican greed at the expense of the fucking species! It's our earth, too, and if we don't get involved we are just as irresponsible as those in power who do little/nothing. Please don't forget about this as summer's heat fades. No, it's not fun, but ignoring won't help this dire situation.

The disintegration of the Larsen B ice shelf in Antarctica was an unprecedented event in geological history
The disintegration of the huge Larsen B ice shelf in Antarctica was an unprecedented event in the past 10,000 years of geological history, a study has found.

Research by scientists from Hamilton College in New York, based on the scrutiny of six ice cores from the vicinity of the ice shelf, found that a collapse of this size had not happened during the period since the end of the last Ice Age.

The piece of ice which sheered away from Larsen B into the sea in 2002 was roughly the size of Luxembourg. The study, published in the journal Nature, shows that the ice shelf had been thinning over the millennia but went through a more rapid loss in recent decades, probably due to global warming.

In March 2002, scientists announced the Larsen B ice shelf on the Antarctic Peninsula had entered a phase of rapid break-up with more than 50 billion tons of ice spilling into the Weddell Sea to form thousands of massive icebergs. It had been known for many years that the ice shelf was thinning and in retreat but the speed of its final collapse astonished scientists. It took just 35 days for the Larsen B ice shelf to fall away completely after a Nasa satellite detected the first ruptures in the 1,255 square miles of ice at the end of January 2002.

Although the disintegration of ice shelves does not itself cause sea levels to rise (because they are already floating), their loss is thought to speed up the flow of ice from ice sheets on land, causing sea levels to rise. Larsen B's smaller neighbour, Larsen A, broke off in 1995 and other much bigger ice shelves nearby, such as the Ross and Ronne, are also considered to be at risk of disintegrating, according to studies by the British Antarctic Survey in Cambridge.

Researchers have measured a 2.5C increase in average temperatures in the Antarctic peninsula over the past 50 years and many scientists believe there is little doubt that this rise can be linked to global warming and climate change exacerbated by man-made pollution.

The latest study by a team led by Eugene Domack analysed oxygen isotopes and the microscopic plankton called formanifera, which are found in ice cores dating back 10,000 years. "We infer from our oxygen isotope measurements in planktonic formanifera that the Larsen B ice shelf has been thinning throughout the Holocene [from the present to 10,000 years ago], and we suggest that the recent prolonged period of warming in the Antarctic peninsula region, in combination with the long-term thinning, has led to collapse of the ice shelf," the researchers said.
