Scientists from Russia, Norway and the USA examined the phenomenon in Arctic waters were discovered microorganisms, traditionally living in tropical and subtropical latitudes.

Scientists have found that the simplest had covered thousands of miles and ended up in the Arctic ocean through the warm Gulf stream. Such cases have already been registered science in 1920, 1930 and 1950, but this time microorganisms "went too far", and attracted a heightened attention of the international scientific community.

Tropical inhabitants were found in the North-Eastern tip of Greenland! Scientists believe that the abnormally high spread of tropical simplest in the Arctic is primarily due to the melting of polar ice. The researchers have named the phenomenon of one of the characteristic evidence of climate change in the polar regions of the planet.
