- Аннотация: Global warming, as one of the important environmental problems of the Earth, can not find solutions without the direct participation of geographers. N.V. Bagrov in the pages of his book «Geography in the Information World» continued the dispute, which for 100 years has been waged between supporters and opponents of Arrhenius's idea about the role of civilization in increasing the content of carbon dioxide in the atmosphere. As well as V.I. Vernadsky, N. Bagrov understood that it was impossible to reduce all the causes of the greenhouse effect only to emissions of man-made carbon dioxide. He pointed to the impossibility of solving the problem only by political methods and invited geographers, oceanologists, geologists to look for «... natural powerful counterbalances to increasing the concentration of CO2 that resist the greenhouse effect» [1]. Scientists have proved that one of the «culprits» of the greenhouse effect is methane, which enters the Earth's atmosphere from its bowels.An example of a cold shelf degassing is the outputs gases from the underwater part of the beach area Laspi Bay. The composition of gas bubbles fluid presents methane, ethane, propane and hydrogen sulfide, it testifies to its deep genesis. Facts about the presence of hydrogen sulfide in the gas require to review the principle of the formation the balance of hydrogen sulphide zone only due biological processes. Without regard modern geological processes, that is taking place in the Black Sea, is impossible to predict the geo-ecological condition of the hydrogen sulphide zone and the position of its upper border.The results of geological research outputs cold degassing of hydrocarbons in the underwater part of the beach area of the bay Laspi confirm that carbonate structures with oasis of life is formed in the active geodynamic environment around the gas jets. It is represented by gravelstones and pebble beds that are cemented with aragonite and calcite. The formation of carbonate cement conglomerates in the beach area is connected with vital activity micro-and macro fauna and flora local biocenosis. High speed cementation of pebble allows to suppose that modern carbonate structures from great depths of the Black Sea and other have a younger age.The authors hypothesize that archaea receive oxygen (for the formation of organic substances and oxidation of carbon and sulfur) at the expense the decomposition of water. In the future, this method of producing oxygen was adopted by cyanobacteria and fauna. Therefore, at the bottom of the Black Sea hydrogen sulphide zone at bacterial mats with modern degassing aerobic fauna finds life are possible.
