Kyiv, August 27 (New Region, Olga Meshcheryakov) – By 2050, the world may appear 150 million “climate refugees”: Scientists predict that by this time many cities will be washed away from the face of the Earth.

The process Global warming continues to affect the world’s oceans. Increase its level due to thermal expansion: increasing the volume of water by heating. In addition, it is a consequence of the melting of ice on land. Cover mountain glaciers have long been reduced around the world, and in the last few years to This added the accelerated melting of ice sheets in Greenland and West Antarctica.

Eight years ago, the Intergovernmental Panel on Climate Change published a report which predicted that the maximum possible increase in the sea level up to the end of the century – 58 centimeters. To date, these data had to be revised. Experts from the US National Oceanic and Atmospheric Administration (National Oceanic and Atmospheric Administration, NOAA) found that the level of the oceans is growing 25% faster than previously thought.

Today, there are changes in previously unseen processes in the climate system. This, in particular, the rapid development of the greenhouse effect in the atmosphere and on the record high temperature of the ocean surface. Each month the temperature records updated: June 2015 was the hottest ever recorded on the planet; Meanwhile, the same conclusion was reached on the same month a year earlier. In 2014 it was recorded 91 tropical cyclone, while for the period 1981-2010 gg. their number, the average was 82. And finally, in every part of the Arctic and in every area of ​​the ice season is now much lower than it was in the 1980s and 1990s.

The combination of all the factors It allows scientists to predict that by 2050 the rise in global sea level will reach five meters. As explained by the Head of the Laboratory of Geoecology MGIMO Natalia Ryazanov, resulting in “a huge number of low-lying areas, where most of the world’s population will be in the flood zone.” In the fall risk area north of Canada and the eastern US, Latin America and the coast of Australia and many other regions – from the Bahamas to Bangladesh. The same fate awaits virtually all coastal cities and even large European cities. Thus, half a century on the planet can appear about 150 million “climate refugees».
