Kinda Wimpy :

A five nation scientific team has published new evidence that even a slight rise in carbon dioxide in the atmosphere affects the stability of the West Antarctic Ice Sheet (WAIS). The research, which was published in the March 19 issue of the journal Nature, is based on investigations by a 56 member team of scientists conducted on a 1,280-meter long sedimentary rock core taken from beneath the sea floor under Antarctica's Ross Ice Shelf during the first project of the ANDRILL (ANtarctic geological DRILLing) research program.
"The sedimentary record indicates that under global warming conditions that were similar to those projected to occur over the next century, protective ice shelves could shrink or even disappear and the WAIS would become vulnerable to melting," said Ross Powell, a professor of geology at Northern Illinois University. "If the current warm period persists, the ice sheet could diminish substantially or even disappear over time. This would result in a potentially significant rise in sea levels." Ice World

Canada's Concern: And They Should Know, They Live There

A record loss of Artic ice made Canada's #1 weather concern for 2007.
Every year Environment Canada publishes the top ten weather or climate occurrences for that year and for 2007, "the dramatic disappearance of Arctic sea ice, reported in September, was so shocking that it quickly became our number one weather story," they said in a statement.
Satellite images of glacier activity in September revealed that the ice had melted four million square kilometers more then the previous low, a 23% decrease.
"Canadians might remember 2007 as the year that climate change began biting deep and hard on the home front," Canada's environment ministry said.
The most noticeable difference took place at Canada's Northwest Passage. The artic route that connects the Atlantic and Pacific was passable for almost five weeks into August and September, a unusual happening.
"Scientists are now even more convinced that the Arctic climate system is heading toward a more ice-free state during the summer months, and that human-caused global warming is playing a significant role." Source.

A Global Warning

UN chief Ban Ki-moon flew to Antarctica on Friday on a fact-finding mission for climate change, becoming the first UN leader to make an official visit to the frozen continent. Ki-moon was taken to Antarctica to get a first-hand look on how global warming is affecting its glaciers.
"This trip, you may call it an Eco-trip, but I'm not here as a choice," he told reporters. "I'm here as a messenger of all the warnings on climate change. I'm here to observe the impact of the global warming phenomena, to see for myself and to learn all I can about what's happening in Antarctica and actually around the world."
Ban Ki-moon also hopes that his tour of the continent will draw politicians to notice the melting glacier dilemma and in turn motivate them to take action. Source.

Evidence of Global Warming That The Trees Remember

Exposed tree stumps, that were once frozen in time under the glaciers of Canada's Garibaldi Provincial Park, are giving geologists new insight into the accelerated rates to which they are melting.
"The stumps were in very good condition sometimes with bark preserved," said Geologist Johannes Koch from Simon Fraser University in Burnaby, British Columbia.
To find out how long the tree stumps have been living in ice, Koch radiocarbon-dated the wood. He discovered that the trees had been buried under tens to hundreds meters if ice for 7000 years! This realization shows that this is the first time these trees have been exposed in that amount of time. There have been many advances and retreats of the glaciers over the past 7000 yrs but none so far as expose these trees.
"It seems like an unprecedented change in a short amount of time," Koch said. "From this work and many other studies looking at forcings of the climate system, one has to turn away from natural ones alone to explain this dramatic change of the past 150 years." Source.
