Scientist 'gob-smacked' at glacier break-up

A massive glacier in Greenland has broken up almost completely within the space of just two years.

The Petermann Glacier is 186 miles long and over 3,000ft in height but in just two years has broken up almost entirely. "Although I knew what to expect in terms of ice loss from satellite imagery, I was still completely unprepared for the gob-smacking scale of the break-up, which rendered me speechless," said Dr Alun Hubbard.

"New pictures have revealed the extent to which a huge glacier in northern Greenland has broken up in just two years, claims a glaciologist."

[s]I can't see the article, they have moved it off the main page[/s]. Found. But isn't that what glaciers are supposed to do?

Glaciers tend to remain fairly stable for centuries. If they suddenly change in years/decades then something has dramatically changed in their environment which needs accounting for. It is very true that glacial retreat is taking place in many parts of the world for the first time in many many centuries. Br Cornelius

As stated before he is shocked by the glacier breaking up, but I am far more interested in the rocks on the right hand side disappearing.

Try this: take a glass of warm water and gently place an ice cube in it. Note the water level. Then note it again when the ice has melted. By how much did it change? When floating ice melts, the water level doesn't change at all. It's when ice on land (glacial ice) melts that oceans start to rise. And melting ice isn't the only cause of sea level rise. There's also expansion of the water as the ocean warms. So how much are ocean levels rising by? Currently about 0.07 cm per year. On the coast of Maine, with its steep cliffs, that means almost nothing. On the shore of Banglade... [More]

Was he saying that its length was 3 x the height of the tower OR its height? The height could still be 3 x the tower's height if it is all below the Earth's surface. Can the top of a glacier be nearly level with the Earth's surface and heaps of it under that level like a floating glacier?
