The next apocalyptic scenario of death of humanity was presented by scientists from the Californian technological institute Caltech. Approximately through 100 million years or at the best somewhere through a milliard on Earth will not remain practically CO2. And, plants will begin to strangle and die. All flesh will follow quickly on them. In history of Earth already repeatedly falling of level of carbon dioxide happened in an atmosphere.And now concentration CO2 makes only small part that was in an atmosphere
planets a few milliards of years back. Plants which take in carbon dioxide in the process of photosynthesis (his greater part goes back into an atmosphere after death of organism) .postepennoe absorption are herein guilty scarcely CO2 takes place by other method. American
scientists are sure that most carbon dioxide take away on itself silicates, constituents considerable part of the earth’s crust. They draw off a carbon from an atmosphere and will transform him in bicarbonates, thus saving him in the bowels of the earth. If so will proceed,
then through the milliard of years photosynthesis on a planet will be halted.Though as to avoid unpleasant development of events, physicists offer to our distant descendants (if such, certainly, yet will live on Earth) to reduce atmospheric pressure of planet to one sixth
from a present at level sea.Some natural processes will change at that rate, and humanity will succeed to draw aside an end yet on 1,3 milliard of years (these information was got physicists by a computer design) of .iskusstvenno reducing pressure is possible,
for example, decreasing maintenance in the atmosphere of nitrogen (this gas makes near 78% gas shell of Earth) of .esli to our descendants it will be succeeded to do such trick, then all of them will live, as though on mountain peaks, where air very razrezhen. It subjects the health of people
to some risk, but in the future will think of certainly, how with it to manage. In fact to save photosynthesis more important. Not specified, true, that the at that rate scientific suggest to do living org to other
influences of atmospheric pressure on events, what be going on Earth. It predicts also, as future changes will affect flora and fauna", — one of authors of work of King-fay Li talks.Kenneth Kaldeyra from the Washingtonian institute of Karnegi, studying influence
level CO2 on life of planet, considers that, in spite of persuasiveness of this research, nobody knows that actually will take place with Earth (and by atmospheric pressure in particular) in so remote future.However, whether a global earthly ecosystem will be able
somehow to keep balance or not, it is important not so, writes membrana. In fact if humanity will not die of shortage of carbon dioxide, then yet death of Earth threatens him sun.It was considered long time, that gradual heating of our planet, related to the increase
volume of a Sun and approaching of Earth to his surface, will become reason of destruction all living approximately through the milliard of years. Another factor which can influence on development of similar scenario will be become by sun wind, slowly and right destroying external magnetic
field of Earth. However during the leadthrough of these calculations another operating force of process – atmospheric pressure was taken into account.New researches of scientists from the Californian university increase this term more than twice. Developed King Fay Li
and by his colleagues from University of California a model shows that a critical for existence of life temperature will be attained much later, than assumed – approximately through 2,3 milliard of years. Then it will become so hot on Earth, that organic molecules
will spontaneously disintegrate on constituents their elements.
