Scientists have made the detailed diagram which reflects when and which kinds of flora and fauna will suffer from global warming.
Bill Hea ,from the Potsdam institute of studying of changes of a climate, for the first time has collected together data of last researches on global warming subject which has generalized in the report .
Today , in comparison with 1750 ,when rapid development of the industry has begun , the mid-annual temperature on the Earth has raised on 0,7 degrees on Celsius. The nearest 25 years it can rise on 0,3 degrees.
First of all , it will endanger ecosystems such as tropical woods located on northeast of the Australia, and also high-mountainous droughty plateaus in Africa. In some countries gathering crops will decrease and shortages of clean water will begin.
During this period, when the mid-annual temperature will raise on one degree , expected already in the middle of century, speed of warming will significantly increase. Acceleration of thawing polar ices will lead to considerable reduction of populations of polar bears and walruses.
On the other hand, because of warming in tropical belts, inhabitants of coral reeves will start to die out. In area of the Mediterranean the number of forest fires will bring to that devastate of many insects will increase. Warming of the rivers in Northern America can lead to mass extinction to a trout and a salmon in them . In Southern Africa, Australia and in high-mountainous areas many kinds of flowers will start to disappear, and in China will start to dry up trees, especially broadleaf and hardwood trees .
Shortage of potable water will increase, and for famine can be lost up to 1,5 billion persons.
In the beginning of following century the average temperature will increase for three degrees in comparison with 1750. The scientist assumes, that as a result of it , tropical woods of Amazon, high-mountainous flora in Australia, New Zealand and the Europe completely will disappear. Besides this ,many kinds of other plants will start to disappear and coral reeves will finally die out. For famine 5,5 billion persons can be lost (according to all available information, the population of the Earth makes 6,5 billion).
Earlier it was informed, that in the event that the mid-annual temperature on our planet will increase all for 1,3 degrees in comparison with existing, changes of a climate become irreversible. Warming will lead to thawing of a permafrost in Siberia ,and that process will liberate in an atmosphere huge quantity of the methane, one of the basic greenhouse gases.
