Melting Glaciers Dramatically Alter Canada's Yukon
Researchers have determined that the rapidly retreating Kaskawulsh Glacier in the Yukon's St. Elias Mountain region cannot compensate for the volume it is losing now each year.
In the 2018 report, State of the Mountains, experts estimated that the glaciers in the St. Elias Mountains are losing more ice than any other alpine area in the country. The mountain range runs from British Columbia, the Yukon and Alaska, and is part of the largest ice field in the world outside of Antarctica and Greenland.
"We as Canadians are stewards of about a third of the world's mountain glaciers and ice caps, so this is our responsibility," Glaciologist Gwenn Flowers told CBC
Flowers said that the Kaskawulsh glacier is losing a half meter (1.6 feet) of ice a year.
"What the glaciers and ice sheets do makes a big difference to global sea levels, and makes a big difference to local environments where they form a water source," she added. .
After decades of retreat due to climate change, the Kaskawulsh Glacier's meltwater abruptly switched directions in the first documented case of "river piracy." For centuries, the meltwater flowed north into the Slims River, but over the course of a few days in the spring of 2016, the water started flowing east into the Kaskawulsh River.
The rerouting of the meltwater dried up the Slims River and cut off the main flow of water to Kluane Lake, exposing sediments and making the area more prone to dust storms. Drivers along the Alaska Highway, which bisects the Slims River valley, often encounter dust storms that obscure the road and slow traffic to a crawl, CBC wrote.
Kluane Lake is the Yukon's largest lake and borders Kluane National Park and Reserve, a UNESCO World Heritage site.
"We're seeing a 20 percent difference in area coverage of the glaciers in Kluane National Park and Reserve and the rest of the UNESCO world heritage site [over a 60-year period]," Diane Wilson, a field unit superintendent at Parks Canada, told CBC. "We've never seen that. It's outside the scope of normal."

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
