Why are Polar Ice Caps Melting?

We are going through the time of interglacial period. During this period, ice melts from the polar caps extending melting rate from its average time. Ice in the arctic region is melting that comprises 3% of the total ice that is present on the earth. The other ice in Antarctic region and Greenland is melting quickly.

The ice is estimated to be 2133 meters thick. The sea level is going to increase up to 61 meters in the world. If all the ice in the Antarctica region melts but the temperature in -37degree C in that region and the temperature never rises above the freezing point than there will be no danger of ice to melt. As Greenland lies near the equator, its temperature is greater than Antarctica where the ice can melt increasing the sea level up to 7 meters.

polar ice Why are Polar Ice Caps Melting?

Some parts of the Antarctica region are getting warmer because of the volcanic activity occurring under the layers of the ice but the good news is that there is no volcanic eruption in that region otherwise it could had been seriously dangerous. It means that the sea level is not increasing quickly because the ice is not melting quickly. The sunlight strikes the ice and then its most parts reflects into the air instead of going into the oceans while some parts are captured on its way by different gasses of greenhouse. The ice gives a cooling effect because of not reflecting sunlight in to the oceans.

The Greenland has some parts that have some parts of their ice level increased because of snowfall but the ice is melting very fast in some other parts. This means that a change can happen but not very quickly, it is possible that the process can speed up later in the century. Methane gas responsible for warming can be released due to the melting of the ice. This gas will cool the region in Europe and warm the tropical water.

According to NASA, the ice in the Greenland is melting at a double speed as compared to the last ten years and Greenland ice could give a rise in the sea level by 20 feet proving harmful for the coastal regions.
