John Pomeroy is familiar with Peyto Glacier’s rapid melting.
He’s a distinguished professor and director of the Global Water Futures Observatories at the University of Saskatchewan, and has studied the ice mass in Banff National Park since 2008, visiting several times a year to adjust weather stations and photograph changes.
But on a helicopter trip through the Canadian Rockies to the glacier one year ago, Prof. Pomeroy and his team of scientists gasped – stunned to see how much it had transformed since even his previous visit.
