THE ICE MELTS – HUMANS SQUABBLE

OK so maybe now you will believe us – us small folk you think are so cute. The ice is melting. What have we been telling you? The ice is melting.

Down here. Up there. In Montana. In Europe. In South America. In Asia.

Melting faster than you thought. Or wanted to admit.

Go to the BBC: see the pictures.

This is Antarctica, our home:

Calculations based on the rate of melting 15 years ago had suggested the glacier would last for 600 years. But the new data points to a lifespan for the vast ice stream of only another 100 years.

Professor Andrew Shepherd of Leeds University says this about the melting ice:

This is unprecedented in this area of Antarctica. We’ve known that it’s been out of balance for some time, but nothing in the natural world is lost at an accelerating exponential rate like this glacier.

Now similar things are happening up north in the Arctic.

Professor Jason Box of Ohio State University, has been studying the melting ice up north with Greenpeace. He has been surprised by the lack of significant ice they encountered in the Nares Strait between Greenland and Canada.

According to the BBC: “He has also set up time lapse cameras to monitor the massive Petermann glacier. Huge new cracks have been observed and it’s expected that a major part of it could break off imminently:

The science community has been surprised by how sensitive these large glaciers are to climate warming. First it was the glaciers in south Greenland and now as we move further north in Greenland we find retreat at major glaciers. It’s like removing a cork from a bottle.

So you are finally seeing the melting ice. But what exactly are some of you doing about it. Banding together to finally confront global warming? Taxing your use of carbon?

How about fighting each other to take advantage of the melting ice? Now that sounds like human beings

The more the ice melts the easier it is to send ships through the North. Russia, Canada, Denmark and the United States all have a strong interest in controlling the northern route. The Russians are having training exercises and firing missiles; the Canadian government is sending its politicians to show how much they care about the far north. Everybody is planting their flags on the ice.

Nobody is asking the polar bears.

Nobody is asking the penguins.
