Saving the Arctic Requires Action on Climate Change and Air Pollution

Arctic temperatures have increased twice as much as the global average in the past 100 years. Recent photos show that thousands of walruses normally resting on sea ice between dives to find food have been forced to crowd ashore because of extreme sea ice melt in Alaska. Such photos have once again reminded us that it is high time we take serious action on climate change if we want to save the Arctic.
