Lack of rainfall cause for up to three weeks of delay for salmon spawning this season
In early October Vancouver Island reached a drought Level 4 which impacted wildlife across the coast. After a mass salmon die off in Bella Bella, concern grew regarding drought and a delayed salmon spawning season. Currently east Vancouver Island is at a drought level of 3, which means adverse impacts are possible, while west Vancouver Island is at a drought level of 2 with less likely impacts. Dave Rolson, Tseshaht First Nation’s fisheries manager, said, “Timing is everything, really, when it comes to fish and when it comes to environmental conditions.”

After decades of dwindling runs, sockeye salmon return to Yukon fishing village in droves
The number of sockeye returning to Klukshu, Yukon, to spawn began to drop off in the 1990s. This year, hundreds of the bright red fish line the small creek that winds through the village. Neither the Champagne and Aishihik First Nations nor Fisheries and Oceans Canada are sure why the fish have returned after decades of steady decline.

Alaska's newest lakes are belching methane
Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born. At first glance, Big Trail looks like any lake. But look closer and there's something disturbing the surface: bubbles.

Team of biologists makes daring rescue of loons trapped in iced-in waters
The openings were left after ice-in started during a cold snap, but didn’t quite finish in the deepest parts of the lake, about a quarter of a mile off shore. The two loons were stuck and unable to take off, because common loons require a water “runway” to push off and get airborne. Farther up the lake, three other loons were stuck in similar fashion.
