The return of over 5,000 kokanee salmon to Kluane National Park in southwest Yukon in 2015 was cause for excitement after the population was nearly declared extinct in 2009.
“Historically about 3,000 kokanee return to the spawning beds, but in the early 2000’s the population plummeted to several hundred, and in 2009 we only counted 20 fish,” says Carmen Wong, ecological team leader with Parks Canada. “So the return of this many fish is truly astounding.”
A bipedal black bear (affectionately dubbed "Pedals") was recently spotted near a New Jersey golf course, reigniting a fire of Internet love that first started in 2014 when the bear was filmed ambling through a New Jersey suburb on its hind legs like a human.
Seen again last fall, people feared that Pedals, whose front paws appear to be injured and/or partly missing, wouldn't make it through the winter but this most recent video shows the bear toddling along at a ...

Permafrost, the frozen ground that underlies Canada’s Arctic, is rock-solid — as long as it stays frozen. But with a warming climate that icy layer is changing, which can spell trouble for infrastructure built on permafrost, including airport runways. Canada’s remote Arctic communities depend on aircraft for essential services, from resupply of fresh food to emergency transport to hospital.
Michel Allard, a geographer at Laval University, studies the effects of changing permafrost on runways ...

For approximately the past 300 years the meltwater of Yukon’s Kaskawulsh Glacier has drained into Kluane Lake via Slims River. This spring it stopped.
The reason, according to Kristen Kennedy, a surficial geologist with the Yukon Geological Survey, is that the Kaskawulsh Glacier has now retreated to a point where the water that once flowed into the Slims is now flowing in the other direction, into the Kaskawulsh River.
“The drainage of the Kaskawulsh is very active,” Kennedy says. “It’s not ...
