First of all, it is necessary to mention that globose warming is a tremendous challenge to the whole humanity. To date, the global scientific community has received the irrefutable proofs of the secular trend of global warming, which serves as an indicator of clime changes on the Earth. The surface temperature of the standard pressure has increased by 0, 74 ?C over the past century. fair(a) temperatures in the Northern Hemisphere were higher than in any 50-year period in the last five hundred years during the second half of the twentieth century, and probably is the highest in the last 1300 ye ars. Thinking about consequences of global warming, Weart (2003) stated that widespread phenomena, such as rising sea levels, melting glaciers and polar ice sheets (particularly in the Arctic), the lessening of snow and ice covered areas of the earths surface, the increase in rainfall in some regions (the eastern part of North and South America, Northern Europe, North and Central Asia ) and a diminution in others, the expansion arid zones (Africa, South Asia, part), more frequent tropical cyclones in the North Atlantic, and so on are connected with global warming.

C (different scenarios), but likely, a greater value go forth have a place - from 2,9 to 6,4 ? C. This will entail an increase in climatic shocks and disasters, such as more frequent and extensive flood, flooding of low-lying coastal areas in one regions, drought and desertification in others. The changes, in turn, will lead to a reduction in agricultural productivity, especially in arid zones, water resources depletion, a dramatic reduction of biodiversity, and a spread of dangerous infectious diseases due to worsening conditions of the existence of a huge hoi polloi of people, especially in the poorest countries and to general regression in human development throughout the XXI century. contention the problem of global warming some researchers declare d that the Industrial Revolution has changed the lives of mankind for the better, but the annual emissions of carbon dioxide and other gases that cause a greenhouse effect, has grown considerably at its very beginning.
