Quote:Hansen notes that greenhouse gases are still the primary cause of climate warming during the past century and will continue to be the predominant agent of warming in the future. The good news is that soot emissions may be more easily lowered than the greenhouse gas variety. "Technology is within reach that could greatly reduce soot," the researchers write, "restoring snow albedo to near-pristine values, while having multiple other benefits for climate, human health, agricultural productivity, and environmental esthetics."
