Will the increased snow cover at lower latitudes reduce warming? (I'm guessing probably yes, due to increased albedo. But, snow is also an insulator, and might be holding ground heat. I don't know which effect will be greater.)
If it does reduce warming, will the amount be significant relative to anthropogenic climate change? (I'm guessing probably not.)
And just out of curiosity, did the Southern Hemisphere experience similar polar disturbances last winter, or in the past few years?
