The unusually high temperatures of present the winter can negatively affect populyatsii of fauna of the Black sea. The Odessa scientists fixed in his aquatorium appearance of rare types of fishes which before never failed to appear in a black sea region. In particular, near Odessa settled marine cock, black gorbil' and pilomida. Research workers which probe a local fauna are inclined to bind the fact of appearance in the sea of unusual varieties to the direct consequences of process of global rise in a temperature. In addition, scientists caution ekosistemy and threats of gradual extinction of traditional fauna from an irreversible change. Manager Oleg Kovtun talks the hydrobiological station of Odessa National University of the name of Mechnikova, that the process of global rise in a temperature can result in a tragedy – whole populyatsii of animals can disappear: «These marine animals to the spring will not be able to set aside caviar, and next year there can be not the young generation, that a sharp slump of quantity of many kinds will be».

Biologists consider that if the rates of rise in a temperature will not diminish, some representatives of fauna can beyond retrieve disappear already over the years.
