Scientists warn mankind – owing to global warming which began already, will change global sea level. And similar changes do not promise to the planet anything good.
Instruction
1. The mother Earth has a huge water supply - it is continental and coastal ices of the Arctic and Antarctica. Universal temperature increase constitutes danger what affects ices – they begin to thaw. For the last hundred years the water level in the World Ocean grew by 10-20 centimeters. At first sight can seem that it is a trifle, however process continues.
2. Scientists predict that within the 21st century water will rise for half-meter (pessimists predict that on 90 centimeters). The intergovernmental group of experts on climate changes considers that for several centuries this level will grow by four-six meters. The prospect to be flooded threatens, first of all, the coastal countries and the island states, such as the Netherlands, Great Britain, Bangladesh, Maldives, Tuvalu.
3. However, water level will constantly not grow in the ocean. Temperature increase and also increase of solar activity will gradually lead to the fact that on the planet the so-called greenhouse effect will be observed. The stratosphere of the planet will contain the raised amount of water, and here oceans on Earth will simply disappear. The certain water basins formed because water it will become constant to arrive from the depths of the planet will meet. On poles there will be heavy rains. However the most part of the planet will turn into the waterless desert. Such future is prophesied by scientists to Earth through 1.1-1, 2 billion years.
4. If people seriously undertake preservation of the environment, the amount of nitrogen in air will decrease, and greenhouse effect will not occur, Earth is all the same waited by the sad future with siccation of the World Ocean, temperature of the Sun steadily grows. However there will be it only through 3-4 billion years. Scientists consider that the similar situation occurred on Venus – the neighbor of Earth.
