The research is the first to directly model how changing climate will affect polar bear reproduction and survival. There have been warmer periods in the past but they were not only cooler than what we will experience if we dont reduce greenhouse gas emissions they were part of natural cycles of warming and cooling. In May 2009 Ken Salazar the secretary for the US.

But the ringed seals and the polar bears that depend on them now face a severe and increasing new threat directly resulting from climate warming. Though the number of polar bears is likely to be greatly reduced in some regions moderate cuts to heat-trapping gas emissions in the coming decades could allow them to persist in.

The rapidly warming weather in spring throughout much of the Arctic in recent years makes the protective snow roof of a birth lair more likely to collapse and melt prematurely. Climactic changes might currently be threatening the survival of polar bears Ursus maritimus but similar shifts appear to have played an important part in bringing the species into existence in.
