A Canadian professor is warning many of the iconic glaciers in the Canadian Rockies will be gone in the coming decades due to climate change. John Pomeroy is the Canada research chair in water resources and climate change at the University of Saskatchewan. He says the state of the glaciers in the Canadian Rockies is "dire right now." "We've lost hundreds of them already, just over the last few decades, and we'll be losing most of the rest over this century - including over most peoples' lifetimes."
