How do I change the water level

How will the water level

Scientists warn mankind - as a result of global warming, which has already begun to change the world's oceans.

And such changes do not promise anything good planet.



Earth has a huge supply of water -This continental and coastal ice in the Arctic and Antarctica. The widespread rise in temperature is a danger that the impact on 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 waterIt will rise by another half a meter (pessimists predict that by 90 centimeters). Intergovernmental Panel on Climate Change says that a few centuries, this level will grow by four to six meters. The prospect of being flooded threatened, primarily, coastal countries and island states such as the Netherlands, United Kingdom, Bangladesh, the Maldives, Tuvalu.


However, the level of water in the ocean is not constantgrow. Temperature rise and increase solar 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 the oceans on the Earth itself simply disappear. individual water bodies will meet, formed due to the fact that the water will constantly come from the bowels of the planet. At the poles will occur periodically showers. However, most of the world will turn into a barren desert. Such a future, scientists predict the Earth through 1,1-1, 2 billion years.


If people take seriously to preservethe 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 of the world's oceans with draining, 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 - Earth's neighbor.
