Scientists have made the long-term forecast of climate global warming consequences, one of which is increase in risk of disappearance 1/3 of plants and animals kinds.
” Approximately, 20-30 % of plants and animals kinds, with high probability, will appear in conditions of increasing risk of disappearance, if the average global temperature will raise 1,5 - 2,5 degrees on Celsius “, — has declared by Jury Israel , director of Institute of a global climate and ecology of Federal Hydrometeorology and Environmental Monitoring Service and the Russian Academy of Science,.
He has noted, that the given conclusion is made in the fourth estimated report of the Intergovernmental Panel of Climate Change (IPCC),which vice-chairman he is.
J. Israel has added, that increase of risk of disappearance 1/3 of plants and animals kinds ,will start probably already in XXI century, however, him as the scientist, doubts of correctness of this conclusion.
Besides this, in report, as he said, it is spoken also about threat of increase of a water level at global ocean on 4-6 meters , in way of gradual thawing glaciers of Greenland and the Western Antarctica, and consequence of it- is flooding coastal territories where live millions people.
As a result, the strongest influence of flooding will be shown in mega-deltas of the rivers of Asia and Africa. Therefore ,small islands can become especially vulnerable. Intensity of thawing of glaciers, as he said, can occur in case the temperature will raise approximately on three degrees on Celsius, however on it will pass thousand years.
” In report is spoken ,concerning the Western Antarctica and Greenland, that problem can occur only in some future centuries or even millennia, i.e. such acuteness catastrophe is removed “, — has noted by J. Israel.
In benefit of Intergovernmental Panel of Climate Change (IPCC), Sergey Semenov ,coordinating and leading author of report IPCC, the employee of Institute of a global climate and ecology, has informed, that according to some scenarios of global warming influence on a climate, in XXI century will gradually increase the quantity of sediments in those regions ,where them already is a lot of (in the majority of continental regions), and will decrease there where it is not enough of them. That will lead to increase in quantity of droughts ,that will adversely effect an agriculture. Activity of intensive tropical cyclones will increase also. Besides this, global warming of a climate in XXI century and further, according to experts, will lead also to demographic expansion of prevalence of infectious diseases.
According to the report, to influence of a varying climate will be especially vulnerable - Arctic regions, Africa, region of Sahara, small islands, the Asian mega-deltas.
In the south of the Europe the increase in temperature and strengthening of droughts will worsen position with water resources, will reduce opportunities of production of the hydroelectric power, will worsen conditions for summer tourism, will reduce production of plant growing, and the risk for health of people will increase owing to waves of heat.
In Central and the East Europe reduction of years sedimentation will reduce water resources, the increase in frequency of fires at turfs is possible also. Thus in the report it is emphasized, that influence of change of a climate will be various in different regions.
