Most polar bear populations could disappear by the year 2100 – scientists
By 2100, the world can hardly remain polar bears, this forecast was made by scientists, reported The Guardian on 20 July.
The researchers warned that if greenhouse gas emissions remain at current levels, by the year 2100 is likely to disappear all of the population of polar bears, except a few in the Arctic. By 2040, polar bears will begin to experience reproductive failure, which will lead to local extinction, the newspaper notes.
Researchers have proposed two scenarios. At the current level of emissions polar bears at the end of the century will probably be able to survive only on the Islands of Queen Elizabeth, the northernmost cluster of the canadian Arctic archipelago. Even if greenhouse emissions are reduced most populations of polar bears in the Arctic will experience reproductive failure by 2080.
According to scientists, the world has less than 26 thousand polar bears scattered across 19 different subpopulations, from the icy landscape of Spitsbergen, Norway, to Hudson Bay in Canada and the Chukchi sea between Alaska and Siberia.
According to scientists, polar bears can be saved only in case if their habitat is protected, and it requires combating climate change at the global level.
