Ice is ice. When the temperatures rise in the ocean it will eventually melt ice everywhere.

Scientists have gained insight into the cause of the global sea level rise with the discovery that warm ocean water is primarily melting the ice shelves.

When iceberg chunks break off (click here) of floating ice shelves, it can serve as dramatic proof of melting — and this traditionally has been considered the main way that these expanses of Antarctic ice become smaller. But new research reveals a disconcerting finding that is invisible to the naked eye: These ice shelves primarily melt from below.

Knowing what is driving ice-shelf melt is important because when ice shelves lose mass, they speed up the flow of land-bound glaciers that feed them, moving ice from the continent to the ocean, and contributing to global sea level rise.

The study, published today (June 13) in the journal Science, found that on average, Antarctica's ice shelves are thinning by about 1.6 feet (50 centimeters) per year. But some of them are thinning much more quickly, by as much as 328 feet (100 meters) annually, said Eric Rignot, a study co-author and researcher at the University of California, Irvine....

Below is the Arctic Ocean (north pole). It is happening. Cold air and water in exchange for ice. Not all anymore. No cold water and air and ice. Now, it is cold water and air at the cost of major ice formations.

Major climate shifts. Yep. It is happening. There is no doubt at all.
