Scientists conducted long-term researches, which allowed to estimate the amount of carbon dioxide, getting in an atmosphere after melting of eternal frigidity. Arctic will begin to supply with approximately one milliard of tons From 2 in a year. For comparison, annually in an atmosphere from
incinerations of hydrocarbons about 8,5 milliards of tons get. It is considered that over melting of eternal frigidity brings to freeing of carbon dioxide, which is the result of vital functions of microorganisms, corrupting old organiku in soil. Thus plants which this gas is taken in appear on thawing soil.
The purpose of researchers was determination of roles of these processes in the general rotation of carbon in nature.For this purpose during three years researchers conducted looking after a few regions of eternal frigidity on Alaska. Through the radiouglerodnogo analysis of carbonate
gas they found out, there is a carbon, included in this gas to youths, that participating actively in a rotation, or this that carbon which was locked during hundreds or thousands of years.As a result they succeeded to set that on the first stage growth of plants outweighs
melting of frozen condition of ground, that with growth of temperature regions take in there is more than produce gas. At the further increase of temperatures a situation changes: in an atmosphere begins to go out old carbon dioxide is so many, that plants do not get along already at him.Using
findings, scientists made an effort extrapolate, that will happen in arctic regions on all planet in connection with growth of middle temperatures. They found out as a result, that Arctic would begin to supply with approximately one milliard of tons of carbon dioxide in a year. For
comparisons, annually in an atmosphere about 8,5 milliards of tons get from incineration of hydrocarbons.The article of researchers appeared in a magazine Nature, and its short exposition leads Nature News.rabota of scientists was perceived by colleagues ambiguously. Many accede to exactness
calculations conducted on Alaska, mark however, that extrapolation of results on all arctic region of nepravomerna from the neodnorodnosti structure of Arctic, reports Lenta.ru. gas – not 2000
melting of eternal frigidity. Some researchers fear that Arctic contains plenty of methane, which possesses a prepotent hotbed effect, than CO2.
