The chunk of the Antarctic ice sheet, the Larsen B shelf, the size of Rhode Island, to collapse in 2002 has been directly linked to global warming scientists said Monday. A shift is the winds around Antarctica, altered by warming ocean currents led to the break up. It is asserted that the warming is caused by the increase in the earth's overall tempature by CO2 and other greenhouse gases mankind has been spewing into the atmosphere for the past 150 years.

OSLO (Reuters) - Scientists said on Monday that they had found the first direct evidence linking the collapse of an ice shelf in Antarctica to global warming widely blamed on human activities.

Shifts in winds whipping around the southern Ocean, tied to human emissions of greenhouse gases, had warmed the Antarctic peninsula jutting up toward South America and contributed to the break-up of the Larsen B ice shelf in 2002, they said.

"This is the first time that anyone has been able to demonstrate a physical process directly linking the break-up of the Larsen Ice Shelf to human activity," said Gareth Marshall, lead author of the study at the British Antarctic Survey.

There are those who claim that global warming is false, or that it is a stellar event affecting all the planets. Whatever. believe what you want to believe but to use such excuses as a reason not to curb the overall pollution of our atmosphere is just plain foolish. Whether global warming is caused by human activity or not is really moot, it's happening and if we can ameliorate it by changing our behavior, it behooves us to do so. To fail to do is short sighted at best, and to claim that it would hurt our economy is just stupid. Conservation is, contrary to Cheney's assertion, not just a private virtue, it should be a prudent national one was well.
