However a computer is an ingenious invention of mankind. By its help scientists can look both in the far-off past, and in the infinite future. Certainly, it is impossible to be absolutely assured that all was or will be, but it is possible to receive a provisional picture of the validity. So, computer modeling has helped to find out the reason of mass disappearance of various organisms on the earth 250 million years ago. Most likely, for many representatives of fauna change of a climate became fatal, and concrete - global warming.
It is necessary to note, that hypothesis about sharp change of a climate of a planet ,which has been caused by extraordinary volcanic activity, the American scientists have put forward a in the beginning of 2005th year. At that time Peter Ward has declared, that all this has led to well-known ” Great extinction ” , which has happened about 250 million years ago. The researcher has named the main reason of this incident -the Siberian volcanoes which have thrown out huge amount of greenhouse gases in the atmosphere. Then the American experts have developed the theory which has been put forward by Peter Ward. For this purpose they have lead very detailed modeling of a climate ,of that epoch, on a computer. As it has appeared, 250 million years ago mid-annual temperatures have rapidly jumped up to that level, which is on 10-30 degrees above nowadays mid-annual temperatures. Thus there were catastrophic changes for many organisms: not only a surface of the ground and the atmosphere have considerably heated up, but still oceans water (on a depth ,approximately, three kilometers).
As a result , at different levels of global ocean streams of water have changed. As consequence in water mass was considerably reduced the maintenance of oxygen, and in many layers it’s became simple insignificant. Thus, ancient sea deep-water substances have simply choked. Such miserable part has comprehended about 95 % of inhabitants of sea depths. The heatstroke should be reflected and in those representatives of fauna who live on a surface of the planet. About three quarters from them also have died out.
Authors of the given research are assured, that, precisely, global warming became the reason of mass extinction on the Earth. At the same time supporters of the version about falling a huge asteroid also have the certain proofs of they truth. Thus, quite naturally, correct can be both points of view. Experts emphasize, that both of the factors, could strengthen the effect, made mutually.
