Summary:For millions of years, Arctic sea ice has expanded and retracted in a rhythmic dance with the summer sun. Humans evolved in this icy world, and civilization relied on it for climatic, ecological, and political stability. But the world creeps ever closer to a future without ice. Last year, new reports documented how record Arctic warmth is rapidly eroding sea ice, and the United Nations Intergovernmental Panel on Climate Change detailed the manifold impacts from declining sea ice in a Special Report on the Ocean and Cryosphere in a Changing Climate. As the northern sea ice declines, the world must unite to preserve what remains of the Arctic.
