Finland's ski centres are coping with shorter, milder winters by making and storing snow – costly short-term solutions that may worsen the problem in the longer term.

The image above shows curious holes in Arctic sea ice, located about 50 miles northwest of Canada’s Mackenzie River Delta. Guesses from readers included everything from ice broken by marine animals to breathe, to ice that had been thawed by methane hydrates. It’s a challenge to know the source of the features based on a photograph or satellite image alone, but several scientists offered their hypotheses in our April 21 Image of the Day.

Biologists flew over southern British Columbia last week to count the number of caribou in the last remaining herd that migrates from B.C. to the U.S. — and what they saw stunned them.

Bull sharks, an apex predator, are moving into the Pamlico Sound as a nursing habitat, and experts are crediting ocean warming as the cause.

We have experienced since Oct. 2 a very unseasonable Alberta winter. High snowfalls, a few Chinooks and certainly we knew some time ago we were in for an interesting spring ... but this is unprecedented...

For a few decades now, retired surgeon Jon Reiswig has lived with a perplexing oddity: the water in front of his North Douglas home constantly bubbles.

Invasive species are a more important issue as increasingly warm winters and wetter summers help grasslands and forests in the North grow like never before, changing the very fabric of the North’s ecosystem.

Wolverines are thought of as shadowy solitary carnivores, few and far between as they wander B.C.'s

Marine heatwaves are growing longer, stronger and more frequent thanks to climate change.

Not only is pollen is beginning to spread, but road gravel dust and studded tyres grinding the tarmac can also cause particulates that cause breathing difficulties. There are a few ways to deal with the dust, however.

The federal government is spending $5.7 million over three years to eradicate introduced deer on six islands on Haida Gwaii.

According to an RCMP news release, the hunter was part of a group of five men hunting for polar bears. The group was 65 kilometres southeast of Clyde River when the man fell through the ice at about 9:30 p.m.

Previously, regulators monitored the presence of certain toxins and shut down fishing when they exceeded safe limits.

Two key factors that govern the Arctic ecosystem are rapidly changing: ice and light. The Arctic is the fastest-warming place on earth, and ice that used to form on the surface of the ocean is vanishing.

The herds are increasingly moving around in Bristol Bay, perhaps seeking new feeding grounds, a biologist said.

We discovered numerous large marine bivalve shells (and two chiton shells) that had been cracked recently by sea otters. Ocean View Beach is around the southern extent of Vancouver Island and back again north in the Strait of Georgia. The present observation is evidence of sea otters traveling into the Strait of Georgia.

Walrus in Bristol Bay and Port Heiden are not uncommon in summer. The fact they are present in April is unusual and residents believe factors such as the lack of sea ice, lack of food and warming ocean temperatures may be the reason.

Eaglecrest is forgoing its annual Slush Cup competition due to low snow levels. The event was canceled in 2015 and 2016 for the same reason, but made a return last year.
