That's basic climate science. When there is more energy available there is more evaporation. When temperature decreases, there is more condensation. What other way would clouds be formed?
So that explains why the tropics get more snow than Canada, and why Africa and Central America dominate the winter Olympics. It's basic climate science.
Increasing southern snowfall in the Northern Hemisphere used to be a sign of the impending ice age. Now it's a sign of global warming. So far 2010 has come in second in Northern Hemisphere snow extent to 1978. What were the suggested solutions back in the 70's? Well, stuff like this:
Newsweek, April 28, 1975
Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects. They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve.
So retreating glaciers are a sign of global warming, whereas surging glaciers are, um, a sign of global warming. Everything is a sign of global warming, which is why it's a religion, not a science.
