Donald Trump might not be interested about the Arctic. Please share this Forum!
Changes in albedo are responsible for a significant fraction of global warming—about one-fourth as much as greenhouse gases, according to a recent study. If you’ve ever walked barefoot from light-colored concrete to black asphalt on a hot summer day, you’ll know what I mean. The increase in darkness due to dirt or wildfire soot or smokestack pollution literally changes the melt rate of the snow, causing it to disappear more quickly. Hence this alarming chart.A recent study showed Northern Hemisphere snow cover is declining faster than climate models have predicted, at a rate that outpaces even the stunning decline of Arctic sea ice. Another line of research has linked fluctuation of snow cover in Siberia and the decline of Arctic sea ice with recent bouts of weird weather in the eastern United States. What happens in the Arctic does not stay in the Arctic.
