Antarctica on the rocks: Major ice collapse is occuring

So we’ve been grumbling the past few days about the latest round of snow and ice that’s descended upon us in the early days of spring. At least we’re a long way from Antarctica.

The National Snow and Ice Center today reported, and released photos, of a huge ice sheet collapse from the cold continent. About 160-square miles of ice have broken free from the Wilkins ice sheet since Feb. 28 in some major league size pieces. While the Wilkins ice sheet is about the size of Connecticut, one large portion of broken ice sheet is seven times larger than the Manhattan district of New York City.

While that’s a big chuck of ice to break free, larger ice collapses have happened two other times since scientists have been monitoring the site: in 1995 and 2002. Yet, the experts are saying that this latest ice break is another sign of global climate change.

Other portions of the ice shelf are hanging on by thin margins and one expert predicts that the entire shelf could be gone in 15 years. Cracks in the thin ice fill with water, which accelerates the melting, and leads to more major ice breaks.

Here's a link to some great video of the fragile ice sheet area from National Geographic.

The latest news about climate change is so alarming (the right wing would say alarmist) as to make many people want to plant their aching heads in the sand. Some scientists using advanced computer models now argue that if we want to stop the Earth from warming, the amount of carbon we should be emitting is ... none. None? As in, zero? As in, shutting down the global industrial economy? After all, global energy demand is expected to accelerate until at least 2020. Yet attempts even to slow the rate of increase of carbon emissions have paralyzed world politics for more than a decade.

How come people keep saying that the Alska animals are going to die in about 3 years?

Of course, Antarctica is just coming out of the Southern Hemisphere summer, when we would expect ice to melt.

According to the New York Times, in 2007 Antarctic sea ice reached the highest level ever recorded. NASA studies indicate that Antarctic sea ice has been increasing for decades. This graph shows current levels of Antarctic sea ice. As of today, it's about 1 million square miles above average, and has been above average for several months.

Of course, things can change. A single data point, like a single event, doesn't tell us much about long-term trends.

it sad that stuff like this can happen and still we do close to nothing about global warming. just think.....if Al Gore won in 2000.

BOOYAKASHA!

[shudder] I prefer not too. ;-)

But seriously, even if human action can roll back global warming, it is extremely unlikely that the actions of one country would have had a measurable effect in just 8 years.

Actually, global temperatures have levelled off and even gone down over the past ten years.

Well is the results of the global warming, if the consequences are so bad. Because the change in the earth are be most presents.

hey guys this could be our solution to global warming a huge ice cube in the ocean and we didnt even have to make it. it will cool us of haha

I didn't realize that stuff is that big. But for 160 square miles to break off,, that is crazy.. Global warming is in affect!!!

Yadadamean!!!

Major ice breaks have occurred in the past. According to NASA, the amount of ice in Antarctica is increasing, which may have something to do with this large break.

ok thats crazy because that means theres a big problem with global warming because of all the ice an snow is melting

i believe that if it weren't for global warming, we'd all be frozen to death. not trying to be gruesome or anything. that's just what i think.
