Researchers at the Japan Global Environment Research Center have shown that Japanese corals are migrating north. And it's happening much faster than they thought, because they've seen a type of coral moving 14 kilometers a year.

This research center has been studying corals since the 1930s. It is stated that in the last 100 years the surface temperature in winter has increased between 0.7 and 2.4 °C. As a result, four of the nine types of coral analyzed have moved to the North Pole, remaining the rest where they were. The four that have moved appear on the list of the International Union for Conservation of Nature since 1998 as "threatened" or "vulnerable."
