The tremendous power of nature: floods, disasters, storms, sea-level rise. Whims of weather are common and these situations become even normal and ordinary. Global warming. We frequently hear this expression, but these familiar words hide a frightening reality. Our planet is warming and this has a disastrous effect on the glaciers. The temperature rises, the ice begins to melt, and the sea begins to rise. Worldwide ocean level rises to 2 times faster than 150 years ago. Many cities may be flooded and millions of people could die. We have already heard news from all over the world about flooding. Mountain glaciers are melting all over the world, and in the last few years, we add to this the accelerated melting of ice sheets of Greenland and West Antarctica.
Eight years ago, the Intergovernmental Panel on Climate Change published a report, which predicted that the maximum possible increase in sea levels before the end of this century would be only 58 centimeters. These data had to be revised now. Experts from the US National Oceanic and Atmospheric Administration (NOAA) found that the level of the oceans is growing 25% faster than previously thought.
Today, there are previously unseen processes of change in the climate system, which include the rapid development of the greenhouse effect in the atmosphere and the high temperature of the surface of the oceans. June 2015 became the hottest ever recorded on the planet. Meanwhile, the same conclusion was reached in the same month a year earlier. In 2014, 91 tropical cyclones were recorded a year, while in the period 1981-2010 their number, the average was 82. In addition, finally, in every part of the Arctic the ice area is now significantly lower than it was in the 1980s and 1990s.
Deforestation is one of the causes of the flood too. When people cut down trees, the ground loses its ability to absorb water and trees do not prevent sediment runoffs, that’s why an unabsorbed water then can cause flooding.
The totality of all factors allows scientists to predict that by 2050 the rise in sea level will reach five meters. As a result, "a huge number of low-lying areas will be flooded. The lands, where most of the world's population is situated." In the risk is the area on north east of Canada and the United States, Latin America and the coast of Australia and many other regions from the Bahamas to Bangladesh. The same fate is waiting for virtually all coastal cities and even large European cities. Thus, on the planet may appear about 150 millions of "climate refugees" in the near future.
