climate change is not only speaks lazy.Unusually hot and dry summers, cold winters with a minimum amount of snow ... In short, the average temperature of the planet has definitely changed.That's just how things have changed, and how it can turn in the not too distant future?
Scientists say that over the last century temperatures have risen by about 3 degrees.It seems to be a trifle, but a meager change in temperature led to a significant change in climatic conditions.Melting ice in Greenland and the Arctic, biologists gloomily predicting the imminent extinction of polar bears and ornithologists write a thesis on a significant change Flyways.In particular, many cranes are now stopped for the winter in a much more close to their habitat areas, rather than just half a century ago.
In general, there are sufficient grounds to assert that the average temperature on Earth has increased significantly.But involved in this phenomenon to a man?Here the views of scientists disagree fundamentally.Supporters of anthropomorphic climate change tend to blame the person, and their opponents argue that humanity is not enough in what contributed to warming.
last argument is a simple mathematical calculations.They show that the average temperature will rise much more from the average power of a volcanic eruption.All the plants of the world for several years, emit less carbon dioxide than one only a couple of days the volcano eruption!If we talk about the powerful eruptions, like the one that destroyed the Cretan civilization, the comparison resembles woodworm beetle and woodworking factory.
Thus, the question of why the Earth's average temperature rose, still remains open.But what will the future warming?
In principle, the consequences can be seen today: expanding desert area, there is a gradual degradation of soil, increases the level of the World Ocean.But not all that bad.
Environmentalists say that if the average temperature will continue to rise, it is in most parts of the country it will be reflected positively.Dramatically increase the growing season of plants, the climate becomes warmer and softer.However, the majority of coastal land will be flooded, and crowds of refugees will flood to safe places, which clearly will not contribute to the stabilization of the political and economic situation in the country.
But there is another danger.And her name - the greenhouse effect.With increasing surface temperature of the planet increases dramatically the content of carbon dioxide in the atmosphere.Initially it just causes warming, which eventually gives way to the cold snap.Around and we start all ice ages on Earth.
So what are we waiting for?To answer this question unambiguously is difficult enough: not enough statistical data.However, a sufficient degree of certainty we can say that the average temperature in the coming decades will still increase.There is no doubt that mankind should be less to play big-time politics and to think more about their own future.
