80% of mountain glaciers in Alberta, B.C. and Yukon will disappear within 50 years: report

Published

Climate change is causing glaciers in Alberta, British Columbia and Yukon to retreat faster than at any time in history, threatening to raise water levels and create deserts, scientists say.

David Hik, an ecology professor at Simon Fraser University, said the region is one of the hotspots for warming and the magnitude of change in the glaciers is dramatic.

“Probably 80 per cent of the mountain glaciers in Alberta and B.C. will disappear in the next 50 years,” he said.

The Peyto Glacier in the Rocky Mountains, part of Banff National Park, has lost about 70 per cent of its mass in the last 50 years, Hik said.

“It’s a small glacier but it’s typical of what we’re seeing,” he said.

Less snow, faster melt

Zac Robinson, a professor at the University of Alberta, said as the climate warms, the fragmentation of some of the large ice caps in the Rockies will continue.

Glaciers are formed when snow accumulates in the winter but doesn’t melt completely the following summer.

As the Earth warms at a faster rate, a combination of less snow and a rapid melt is causing glaciers to recede in length and volume, Robinson said.

The first State of the Mountains report, co-authored by Hik and Robinson and published in May by the Alpine Club of Canada, says outside of the ice sheets of Antarctica and Greenland, Canada has more glacier cover than any other nation.

Of the estimated 200,000 square kilometres of Canadian glaciers, one quarter is found in the west of the country and the remainder are in the Canadian Arctic archipelago.

St. Elias Mountains melting fastest

Robinson said mountain glaciers, given their sensitivity to warming, are showing the earliest and most dramatic signs of ice loss, and the St. Elias Mountains in Yukon are losing ice at the fastest rate.

“Yukon glaciers in the St. Elias ranges have lost approximately one-quarter of ice cover since the 1950s,” he said.

Scientists studied the glaciers using a number of methods, including analyzing old photographs and remote sensing.

Hik said the rate of melting varies in different places in Western Canada.

“We don’t have detailed measurements everywhere but where we have measurements the rates can be 25 to 70 per cent [of melt] in the last six to seven decades.”

The rates of melting are similar to what is seen in the European Alps and the Andes, he said.

One of the first effects of melting glaciers is an increase in sea level, Hik said.

Melting of the St. Elias glaciers accounted for a 1.1 millimetre increase in sea level rise in the last 50 years, Hik said.

“That doesn’t seem like very much, but if you take the St. Elias Mountains, the Rocky Mountains and high Arctic mountains and the Himalayas-Hindu Kush and the Andes and the Alps, and if you put all of those contributions together, it counts for one of the largest increases in sea level over the past decade.”

Droughts and dust bowls

While the melt increases water levels and sets off coastal erosion and flooding, it also causes dry areas and dust bowls.

As glaciers recede, more water flows downhill, but the further the ice sheets retreat, the less water there is to go down stream and soon the area begins to dry, Hik said.

“In places like the Kluane River in Yukon there is significantly more dust because the valley that the river flows through is essentially dried out,” he said.

But the area still experiences katabatic winds — winds coming off the glacier — which are quite strong and blow the dust from the dried stream beds further out on the landscape, Hik said.

This dust can create problems for vegetation by settling on trees and plants, and reducing photosynthesis, he said.

Glaciers act as a bank account during hot summers when water is scarce, Hik said. The melt also changes the way water flows and where it accumulates.

“In some places you’ll have locally increased water availability and in many, many, many places that water availability will be reduced as well,” said Hik.

Robinson said mountains are recognized as sentinels of change because they respond rapidly and intensely to climate changes.

“Mountains give an important glimpse into the future and can show us what’s coming down the line,” he said.

Ottawa performer leapfrogs from gymnastics to Broadway to TV

Published

By

A new AppleTV+ series set in a magical town that’s stuck in a neverending 1940s musical includes a pair of Ottawa siblings in the cast. 

Warren Yang and his sister, Ericka Hunter, play two of the singing, dancing residents of the village portrayed in Schmigadoon!, a small-screen series that takes its cues from classic musicals like Brigadoon, Wizard of Oz and Sound of Music, and skewers them with the offbeat comedic mastery of Saturday Night Live. 

In fact, you’ll recognize many of the names from SNL, starting with executive producer Lorne Michaels, creator of the late-night, live-comedy sketch show. Schmigadoon! also stars SNL cast member Cecily Strong and comedian Keegan-Michael Key, who hosted SNL in May. They play a New York couple who get lost on a hike and stumble into a strange town where everyone sings and dances. 

For Yang, a relative newcomer to show-biz, the series marks his television debut. For Hunter, the younger of his two older sisters, it’s the latest in a career path that began with dance lessons as a child more than 30 years ago. She attended Canterbury High School, Ottawa’s arts-focused secondary school. 

“Her dream was always to perform,” said Yang, 34, in an interview. “But that was never the path I thought was an option for me.” 

While his sister studied dance, Yang did gymnastics. He was an elite gymnast throughout his youth, ultimately leaving Merivale High School at 16 to train in Montreal, finishing high school through correspondence courses. He was a member of the Canadian National Team and received a scholarship to study at Penn State, majoring in marketing. 

A few years after graduation, Yang was working at an advertising agency in Toronto when he got a call from a Manhattan number. To his astonishment, they asked if he would be interested in auditioning for a Broadway revival of Miss Saigon.

COVID-19: uOttawa to require vaccination for students living in residence

Published

Vaccination will be mandatory for students who want to live in residence at the University of Ottawa this year, with proof of vaccination and at least one dose required before move-in, or within two weeks of doing so if they can’t secure a shot before arriving.

Those who can’t receive a vaccine for “health-related reasons or other grounds protected under the Ontario Human Rights Code” will be able to submit a request for accommodation through the university’s housing portal, according to information on the university’s website.

Students with one dose living in residence will also have to receive their second dose “within the timeframe recommended by Ottawa Public Health.”

People who haven’t been granted an exemption and don’t get vaccinated or submit proof of having done so by the deadlines set out by the school will have their residence agreements terminated, uOttawa warns.

“Medical and health professionals are clear that vaccination is the most (effective) means of protecting people and those around them,” reads a statement provided to this newspaper by uOttawa’s director of strategic communications, Patrick Charette.

Article content

“It is precisely for this reason that the University of Ottawa is requiring all students living in residence for the 2021-2022 academic year to be fully vaccinated. The University recognizes that some students may require accommodations for a variety of reasons and will be treating exceptions appropriately.”

Faculty, staff and students are also strongly encouraged to get vaccinated, the statement notes.

“Ensuring a high vaccine coverage in all communities is critical to ensuring an ongoing decline in cases and ending the pandemic. This will be especially important with the return of students to post-secondary institutions in our region in the fall of 2021.”

Neither Carleton University nor Algonquin College is currently mandating vaccination for students living in residence, according to the websites for both schools. But uOttawa isn’t alone in its policy – Western University, Trent University, Durham College and Fanshawe College have all implemented similar requirements. Seneca College, in the GTA, is going even further, making vaccination mandatory for students and staff to come to campus, in-person, for the fall term.
