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.

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...

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.

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.

So far in 2018, there have been three climate and weather disasters that have cost $1 billion or more.

An early melt-out date can make for an especially bad wildfire season, but this year, it’s right on schedule for much of the state. Listen now

When Jazmin James hadn’t returned to Tununak by Easter Sunday as planned, the family reported him missing. His snowmachine was found on sea ice, partly submerged in water.

Footage shot across the North Atlantic captured a stunning view of accumulating sea ice over Brighton, Newfoundland, but, according to researchers, also serves as stark reminder of the impact of climate change.

Thinner sea ice and melting permafrost. Is it related to changes in the Earth's axis?

Permafrost thaw is affecting houses, roads, and ice cellars.

New research led by U of T Mississauga geographer Igor Lehnherr provides startling evidence that remote areas in Canada's Arctic region—once thought to be beyond the reach of human impact—are responding rapidly to warming global temperatures.

After admitting a sick ringed seal from Unalaska, veterinarians at the Alaska SeaLife Center are cautiously optimistic about his chances for recovery.

Researchers from the Universities of Bremen and Innsbruck have shown in a recent study that the further melting of glaciers cannot be prevented in the current century—even if all emissions were curtailed. However, due to the slow reaction of glaciers to climate change, human activity will have a massive impact beyond the 21st century. In the long run, 500 meters by car with a mid-range vehicle will cost one kilogram of glacier ice. The study has now been published in Nature Climate Change.

Sea ice around Helsinki becomes more precarious as spring draws near.

Considerable danger of avalanches in East Iceland has led to evacuations in the town of Seyðisfjörður.

The Kuskokwim River now has its longest ice road ever, despite having the warmest winter on record.

A new study estimates that climate impacts to public infrastructure in Alaska will total about $5 billion by century's end.
