His uncontrollable "behavior" - one of the themes of the UN Conference on Climate Change, held from November 29 to December 10 in Cancun (Mexico).

Under the threat of flooding are St. Petersburg, Yamal Peninsula, northern Germany and the Netherlands, the Nile delta and the Ganges, predicts the head of the department of Oceanology, Geography Faculty of Moscow State University Sergey Dobroliubov.
