So as the planet warms, these clouds have less ice available to turn to water, which is a problem, because water is good at reflecting sunlight away from earth, and we were kind of banking on this whole ice-to-water transition as a natural way to slow warming. "According to the study published Thursday in the journal Science, computer model simulations say there is more ice and less...
