Researchers, engineers flock to Yukon to see permafrost thaw in action

Kathrin Maier, a PhD student in environmental engineering studies permafrost-thaw slumps, but before this week she'd never seen the phenomenon up close.
Maier, who works in Switzerland at the university ETH Zurich, is among the delegates in Whitehorse this week for the International Conference on Permafrost. She said she was excited to be in "permafrost territory."
"I've never seen [a thaw slump] in my life, and it's just like a 30-minute drive [away]. So I think that's actually an amazing opportunity, to have it here and really see the stuff we research on, in person," she said.
"Especially if you do remote sensing, and you normally don't get into the field."
The international conference happens every four years and this is the first time since 1998 that it's been held in Canada. It brings together scientists, engineers, and people who live on the land, to talk about the latest research on permafrost thaw, and adaptation.
"We wanted to bring the international community to the North, to a place where they see people living on permafrost and [see] the change that's happening currently in a permafrost environment," said conference chair Lukas Arenson, who's a consulting engineer based in Vancouver.
The event — which began Sunday and runs until Thursday — involves oral presentations as well as online discussions for people who are not there in person.
"The permafrost... the frozen ground, brings us together," Arenson said.
As part of the conference, Arenson said it was important to arrange field excursions to see evidence of environmental change.
In the Yukon, thawing permafrost has long posed a threat to infrastructure such as buildings and roads. Just west of Whitehorse on the Alaska Highway, a permafrost slump has recently been threatening part of the highway as it has slowly moved closer to the road.
As a result, the territorial government announced last year that it will move the road out of concern for its "long-term viability."
"We're making sure that while the researchers, engineers, are here, they're not just sticking here to the Kwanlin Dün Cultural Centre, but they go out into the land and have the opportunity to see permafrost in action," Arenson said.
Claire O'Hagan, a master's student at York University who studies permafrost thaw in the Mackenzie Delta region, said it's important for researchers to work together and share knowledge.
With the B.C. NDP and B.C. Conservatives neck and neck heading into election day on Saturday, there are also a record number of Independent candidates who — if voted in — could hold the balance of power in a minority government scenario. British Columbians have only elected one Independent MLA in the last 60 years. Vicki Huntington won a seat in 2009 and was re-elected in 2013. But University of the Fraser Valley political scientist Hamish Telford said the situation could be different this election cycle. Of the 40 Independent candidates running, six of them are incumbent MLAs, who carry the benefit of name recognition in their community. "So we've got Independents in this election who I think we could deem to be viable shots at actually winning a riding, which is not normal," Telford said. "They're still long shots, but they are certainly plausible candidates."
Though Bill C-282 has received cross-party federal support in Ottawa, Alberta's provincial government says it's not a backer of the Bloc Québécois legislation that aims to prevent Canada's supply-managed sectors — dairy, poultry and eggs — from being included in future international trade negotiations.
A former Canadian Olympic snowboarder and 15 others are facing criminal charges for allegedly running a drug-trafficking operation that shipped hundreds of kilograms of cocaine from Colombia to Canada and used violence — including murder — to achieve the group's goals, the U.S. Department of Justice (DOJ) announced Thursday.
