Scientists predicted an early global catastrophe


A group of American researchers discovered that by the end of the century large coastal cities around the world are likely to be flooded due to a rise in sea level by more than half a meter. The article of scientists is published in the Proceedings of the National Academy of Sciences journal.

Experts analyzed satellite data obtained over 25 years to build climate models predicting sea level rise. It turned out that since 1993, the rise of the waters of the World Ocean is accelerating by an additional 0.084 millimeters per year. Considering that the average growth for this period is estimated at 2.9 millimeters per year, in the period from 2005 to 2100 the ocean will rise by 65 centimeters.

Climate models predicting that sea level rise will be a constant value predict growth of 30 centimeters over the same period. In the new study, scientists evaluated the expansion of the ocean's volume due to heating, the amount of melting ice and the influence of volcanoes.

The reason for the floods that hit the coasts of South Florida, Bangladesh, Shanghai and part of Washington, experts call the catastrophic melting of glaciers in Greenland and Antarctica due to global warming.
