The unusual weather patterns in the winters of the Arctic has taken a toll on the wildlife there and will only continue to get worse if this climate change continues. Polar bears are enduring stress with the weather which is forcing the bears ashore sooner and delaying their return to the ice later than usual. The bears are also getting less time to fatten up, which means less energy stored in their bodies. This is particularly an issue for female polar bears; without enough energy stored up, they will not be able to reproduce. The polar bear population in Hudson Bay Canada has already decreased by 20%.
