While reading the Daily News today I came across this article. It's very disturbing to say the least.

12,000-year-old iceberg collapses
Associated Press

An enormous floating ice shelf that is believed to have existed in Antarctica since the last Ice Age 12,000 years ago collapsed this month with staggering speed during one of the warmest summers on record there, scientists say.
Scientists stopped short of blaming the collapse on global warming caused by human activity. But they noted that the ice shelf had persisted through previous climate changes well before civilization began altering the environment.

"It's a profound event," said geologist Christina Hulbe of Portland State University. "This ice shelf has endured many climate oscillations over many thousands of years. Now it's gone."

Satellite images show that the piece of the Larsen Ice Shelf collapsed during a five-week period that ended March 7. It splintered into a plume of drifting icebergs.

The collapsed area was designated Larsen B, and was 650 feet thick and with a surface area of 1,250 square miles, or about the size of Rhode Island.

Larsen B is separate from a new, giant iceberg that satellites are tracking off Antarctica.

The iceberg - designated B-22 - broke free from the Thwaites Ice Tongue, a peninsula of ice and snow extending into the Amundsen Sea on the other side of the Antarctic Penninsula. B-22 is about 53 miles long and 40 miles wide, according to the National Ice Center operated by the Navy.

The Larsen ice shelf is on the Antarctic Peninsula and extends about 1,000 miles closer to the tip of South America than the rest of the Antarctic continent.

In recent months, with the polar summer just starting, temperatures were already creeping above freezing in the region.

I did hear about this.
Considering that the climate is warming....and the 12,000 years of stability...I suppose it's just the "way of nature".
How wonderful it is that we (humankind) were able to recognize that it even took place! [Smile]

To be honest, I'm not surprised this has happened. I saw a documentary a couple of years ago and this was mentioned. Even then, scientists and what not were keeping a close eye on it. I said to myself while watching, it's just a matter of time. I wasn't as optimistic as the experts interviewed for the show were.
Talk about going to the hot spot in a hand basket!! And people still ask me why I chose not to have children. This sort of thing is part of the reason. We've realized our mistakes and are trying to fix them, but it may be too late.
