Earth has a huge supply of water - a continental and coastal ice in the Arctic and Antarctica.The widespread rise in temperature is a danger that affects the ice - they begin to melt.Over the past hundred years, the level of water in the oceans has increased by 10-20 centimeters.At first glance it may seem that it is a trifle, but the process continues.
Scientists predict that during the XXI century water will rise another half meter (pessimists predict that by 90 centimeters).Intergovernmental Panel on Climate Change believes that in a few centuries, this level will grow by four to six meters.The prospect of being flooded threatened in the first place, the coastal countries and island states such as the Netherlands, the UK, Bangladesh, Maldives, Tuvalu.
However, the level of water in the ocean will co
ntinue to grow.Temperature rise and increase solar activity will gradually lead to the fact that the world is observed a so-called greenhouse effect.Stratosphere Planet will contain an increased amount of water, but in the oceans of the world simply disappear.Will meet individual water basins formed by the fact that the water would be constantly coming from the bowels of the planet.At the poles will occur periodically showers.However, a large part of the planet will turn into a barren desert.Such a future, scientists predict the Earth through 1,1-1, 2 billion years.
If people seriously take on the preservation of the environment, the amount of nitrogen in the air to fall, and the greenhouse effect will not occur, the Earth is still waiting for the sad future with draining the world's oceans, because the temperature of the Sun is growing steadily.However, this will happen only 3-4 billion years.Scientists believe that this situation has occurred on Venus - the Earth's neighbor.
