What the report and analysis at The Corner don't report is that as global temperatures have increased since the 1960's, the U.S., E.U., and other developed nations have reduced their dirty emissions. It is developing nations (i.e, CHINA) that are spewing the stuff that dirties the snow, and warms the Earth.
Dirty Snow May Warm Arctic As Much As Greenhouse GasesScience Daily — The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism – dirty snow – can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.
Snow becomes dirty when soot from tailpipes, smoke stacks and forest fires enters the atmosphere and falls to the ground. Soot-infused snow is darker than natural snow. Dark surfaces absorb sunlight and cause warming, while bright surfaces reflect heat back into space and cause cooling.
But that doesn't fit the political priorities of the UN and MSM (i.e., SOCIALISM) and will not be reported.
