The heat is on; can we turn it off?

Andrew Guzman quoted in Men’s Health, May 24, 2013

“Eventually, in this century, a very large share of [glaciers and snowpack] will shrink to the point of no longer being of value as water-storage tools. For the first time in human history you have cut off that water supply, or at least dramatically diminished its value. More flooding in wet periods. More drought in dry periods. California’s going to have a water crisis by 2050.”
