Sea level Raise

The new climate research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change. The global climate in the future century will be 2-4 degrees warmer than today, but the ocean is much slower to warm up than the air and the large ice sheets on Greenland and Antarctica are also slower to melt.

The great doubt in the calculation of the future rise in the sea level lies in the indecision over how rapidly the ice sheets on land will melt and flow out to sea. The model predictions of the melting of the ice sheets are the source for the Intergovernmental Panel on Climate Change's predictions for the rise in sea level are not accomplished of viewing the rapid changes observed in recent years.

Rise in see level

Supercilious that the climate in the upcoming century will be three degrees warmer, the new model predictions indicate that the ocean will rise between 0,9 and 1,3 meters. To move up so much so quickly means that the ice sheets will melt to a large extent faster than before believed. The experimental says that the ice sheets react more rapidly to increases in temperature than experts thinking just a few years ago. And studies from the ice age show that ice sheets can melt quickly.

When the ice age wrecked 11.700 years ago, the ice sheets melted so swiftly that sea stage rose 11 millimeters per year equivalent to a meter in 100 years. In the existing circumstances with global warming, Aslak Grinsted believes, that the sea level will rise with the same speed is to say a meter in the span of the next 100 years.
