Liquefy glaciers has accelerated threefold
Approximate fifty leading experts on climate science in the world have studied the thaw out of polar ice, which is the main reason for the increase in water level in the oceans. Space satellites have helped researchers identify how decline in volume of glaciers in the Arctic, Greenland and Antarctica. It turned out that the glaciers are melting three times faster than a couple of decades ago.
Moreover, global warming will continue to call this process, threatening to become the main cause of flooding large number of cities. Recent technological developments have helped the team of scientists under the strict guidance of Andrew Sheppard from one of the universities in the UK to get rid of errors in estimating the rate of decrease of the ice. Ten satellites of the European Space agency NASA and helps professionals to monitor the ice masses from a variety of angles, and results were systematized.
The study found that the level of water in the oceans has increased from 1992 to eleven millimeters. Each year, it increased by about 0.95 millimeters, which is almost three times higher than two decades ago.
Moreover, the melting of ice blocks is uneven. Greenland is currently losing ice to 5 times faster than in 1992. According to latest information, the northern and southern polar caps dropped about 2940 and 1.32 trillion tons of ice mass.
Experts still refuse to make any specific predictions, but some things are very clear. According to Sheppard, this study can help in understanding the destructive process of melting ice masses and to develop ways to combat them.
Long-term forecasts of the leading exchange organizations to consider the increase in the level of water in the oceans as one of the most significant factors of the economic situation within 50-100 years.
