Alberta glacial melt about 3 times higher than average during heat wave, glaciologist estimates

The heat wave that scorched most of Western Canada last week accelerated the melting of alpine glaciers, a glaciologist at the University of Alberta told the Calgary Eyeopener on Tuesday. "It's very concerning," said Jeffrey Kavanaugh, an associate professor of earth and atmospheric sciences. In the mountains, temperatures cool down about 1 C with every 100 metres of elevation gain — but when record-breaking temperatures swept through the Rockies, even the highest alpine regions couldn't escape it.

A second chance: Canada, U.S. renegotiate a critical water treaty

A second chance: Canada, U.S. renegotiate a critical water treaty

The Columbia River Treaty, an international agreement governing the flow of water between British Columbia and six U.S. states, will be 55 years old this year. It has not aged well. The river springs from the Columbia Icefield in the Rocky Mountains of B.C. and winds 1,930 kilometres through the Northwestern United States – Washington, Oregon, Idaho, Montana, Nevada and Wyoming. No other river in North America spills more water into the Pacific Ocean.
