Greenland ice sheets may be gone soon

A recent study has said that ice sheets in Greenland might completely melt due to increasing global warming. For the first time, scientists mapped the behaviour of the massive ice sheets that existed in northern Europe at the time of the last Ice Age.

The study, published in Science, said that ice sheets could react quite differently depending on the climatic conditions at the time global warming occurs sometimes actually growing larger and sometimes rapidly disappearing, depending on whether increased snow offsets melting effects, or not.

The study further said that that a net gain in ice in Antarctica, would not be enough to offset the melting of the Greenland ice sheet. By itself and without any offsetting mechanisms, a collapse of the Greenland ice sheet would raise sea levels by about 20-25 feet.

One prediction is that sea levels should increase by a foot or two by 2100, and up to 25 feet within 500 years.
