The sharp cooling in the polar regions and the sudden extinction of mammoths.The theory of the dome is easy to solve the problem of extinction of mammoths.Frequent in the north of Siberia finds frozen mammoths. The problem of the extinction of mammoths is now in northern Siberia is not the huge amount of food that you want to live a mammoth - mammoth need food more than an elephant. And in the north of Siberia, a bitter cold (from -40 oC to -60 oC),neither mammoth nor elephants adapt to such low temperatures can not. In thevery short summer and a low solar radiation, the opportunity to grow plantssuitable for food for these giants simply negligible. Speculation that the mammoths were able to adapt to the moss, lichens and dwarf plants alsoquestionable. Also extinct praslonov find in the mouth with colors that are out there just do not grow. So, now as in the Arctic regions are not living mammoths and food for them is missing, it can be assumed that once prevailed in the earlyArctic warm climate with plenty of food for the mammoths.Theory of steam dome may explain the disappearance of the dinosaurs andmammoths, and geochronology to uniformitarian (ie no accidents) isinexplicable. In the fall of an asteroid to Earth, which split the former single continent, water vapor over the Earth’s atmosphere condensed and fell as a powerful storm of rain, fell 12 meters of precipitation. This rain also made ​​a partial contribution to those mudslides that washed away the animals to form astratigraphic layers. With the collapse of the dome had disappeared and the greenhouse effect on Earth and as a consequence - a cold snap.
