A "heated pool" appeared in the Pacific Ocean.

German scientists have said that there is a large "heated pool" in the northeast Pacific Ocean - an abnormally warm zone that appeared as a result of human activity, and not natural climatic changes. It provokes local sea heat waves. Because of this, animals die in the ocean and droughts occur on the coast. Over the past 20 years, 31 marine heat waves have been recorded in this region alone - in the period from 1982 to 1999 there were only nine. More than 100 million fish and half a million birds have died in the United States as a result. The number of sea lions, humpback whales and other animals has fallen.
