Fifty years ago, winter didn’t just visit the Great Lakes — it took up residence. If you blinked too slowly, your eyelashes froze together. Standing on the ice at the edge of Lake Superior, just after an early January snowstorm, everything was white and still, except for the lake. The wind had swept across it revealing ice cracked along thunderous fractures…

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.

As the helicopter turned toward Peyto Glacier, located in the Park Ranges of the Canadian Rockies, John Pomeroy and his team of scientists gasped.
Prof. Pomeroy, a distinguished professor and director of the Global Water Futures Observatories at the University of Saskatchewan, has studied the ice mass in Banff National Park since 2008, visiting several times a year to adjust weather stations and photograph changes.
He is familiar with the glacier’s rapid melting. It retreats tens of metres per year – 80 metres in 2021 alone. But on the helicopter ride last September, he was stunned to see how much it had transformed since even his previous visit…

In the 30 years since global leaders first gathered to discuss how to limit climate change under the United Nations Framework Convention on Climate Change, Earth has lost close to 8 trillion tonnes of ice1 and the atmospheric concentration of the potent greenhouse gas, carbon dioxide, has risen from 350 to 430 parts per million2 — a level last experienced about 2.5 million years ago at the beginning of the Pleistocene Epoch in which humans later evolved.
As a result of greenhouse gas concentration increases, temperatures are rising quickly and our weather is becoming more extreme. We now stand on the cusp of major losses to Earth’s major polar ice sheets in Greenland and Antarctica. These changes are happening much sooner than many scientists’ previous worst-case scenarios.3 They spell the end for both low-lying nations and coastal regions, as maps of coastlines are redrawn by rising seas,4 as well as for wildlife such as polar bears, seals, and Antarctic penguins that have evolved to thrive in these frozen zones.
But they are also set to strike all of us, much closer to home. And it’s hard to imagine anywhere that will feel the force of these changes as acutely as Alberta…

BANFF – The snowpack shortage in the mountains could pose dangerous conditions this summer.
Canmore’s John Pomeroy, one of the world’s leading snow and ice hydrology experts, said the snow water equivalent is hundreds of millimetres below normal for this time of year, generally at between 65 and 85 per cent of normal for high elevation snowpacks in the Bow River Basin and Kananaskis Country…

Prominent hydrologists are sounding the alarm as another dry summer in southern Alberta — with the possibility of water restrictions — is coming into focus.
Water levels are low. Really low.
“The snowpacks in the mountain headwaters of the Bow River, the Oldman River, Red Deer River and North Saskatchewan River are generally extremely low, some of the lowest I’ve ever seen,” John Pomeroy told CBC News in a Tuesday interview.
