Under the testimonies of the scientists who have gathered session of the American Geophysical Union .process of warming on the Earth really has global character, informs CNN.
In particular, Greenland experiences the first wave concerning warm weather since 1930. For last year the area of thawing of an ice cover has increased for 16 percent, that is the greatest parameter for 24 years of measurements.

Ices of Arctic ocean were reduced to 4 percent. Such reduction has not been registered for all period of supervision since 1978.
In tundra bushes succeed in those areas ,on which only 50 years ago did not grow any vegetation.
If these changes to consider separately they only testify about warming a climate in concrete regions. However, taken as a whole, they incontestably prove global process of warming, consider scientists.
Behind warming there can be changes of air and sea streams, but the activity of the human, which has resulted, for example, to formation of ozone gaps, also refers to it. The human certainly influences an environment, however a degree of importance of this influence is not certain yet by scientists opinion.
