80% of mountain glaciers in Alberta, British Columbia, and the Yukon are disappearing within 50 years.

Climate change makes glaciers in Alberta, British Columbia, and the Yukon 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 area was one of the hot spots for warming and the magnitude of change in glaciers was dramatic.
The UN report on global warming would lead to life and death warnings “Probably 80 percent of mountain glaciers in Alberta and British Columbia will disappear over the next 50 years,” he said.
The Peyto glacier in the Rocky Mountains, which is part of Banff National Park, has lost about 70% of its mass over the past 50 years, HIK said.
“It’s a little glacier, but it’s typical of what we see ,” he says.
Less snow, a faster source Zac Robinson, a professor at the University of Alberta, said the weather is warming up, breaking some of the major ice caps in the Rocky Mountains will continue.
In winter, glaciers are formed when the snow accumulates, but it does not melt quite the following summer.
As Arctic warming accelerates climate change–and its damage spreads, as the Earth warms faster, a combination of less snow and rapid melting makes glaciers dwindle in length and volume, Robinson said.
The first state of the Mountain report, co-written by HIK and Robinson and published in May by the Canadian Alpine Association, says outside antarctic and Greenland ice sheets, Canada has more ice cover than any other nation.
Of the approximately 200 000 square kilometres of Canadian glaciers, a neighborhood is located in the western part of the country and the rest in the Canadian Arctic Archipelago.
The fastest mountains in St Elias, Robinson said mountain glaciers show the earliest and most dramatic signs of ice loss due to their sensitivity to warming, and St Elias Mountains in the Yukon lose ice faster “The Yukon glaciers in the St. Elias mountains have lost about a quarter of the glacial deck since the 1950 years ,” he said.
The scientists studied the glaciers using various methods, including analysis of old photographs and remote sensing.
HIK says the Meldrat varies from different locations in Western Canada.

Fusion rates are similar to what is seen in the European Alps and the Andes, he says.
One of the first effects of melting glaciers is an increase in sea levels, said HIK.
The melting of St Elias glaciers originated in the last 50 years for an increase of 1.1 millimeters in sea levels, said HIK.
“It doesn’t look like much, but if you take the mountains of St Elias, the Rockies and mountains of the upper Arctic and the Hindu Kush Himalayas and the Andes and the Alps, and when you summarize all these contributions, this is one of the biggest increases in sea levels during the last give Each. “Droughts and dust husks while melting increase water levels and cause erosion and coastal flooding, also causing dry areas and dust husks.
As glaciers retire, more water flows downhill, but the more ice leaves are removed, the less water is expected to drip and soon the area begins to dry, says HIK.
“In places like the Kluane River in the Yukon, there is much more dust because the valley through which the river flows has essentially dried up,” he said.
Countries agree on the rules of the Paris climate agreement at COP24. But the region remains plagued by katabáticos winds–The winds coming from the glacier–that are strong enough, blowing the dust from the dry creek beds farther into the landscape, HIK said.
This dust can cause vegetation problems
