A Yukon school could soon require constant electricity during the summer merely to avoid sinking. The 'active refrigeration system' would freeze ground under the Ross River school. The device would be the first of its kind in Yukon.

Permafrost underneath the structure is believed to have melted since last fall and key parts of the building might not be able to withstand strong winds or an earthquake, according to a professional engineer hired by Dawson City.

Researchers have found a correlation between melting Arctic sea ice and changes in the planet's largest water circulation system that could lead to the collapse of the Atlantic Meridional Overturning Circulation (AMOC).

The celebrity glacier on the Kenai Peninsula, though relatively small and getting smaller, looms large in the public consciousness.

By the end of the century, the global temperature is likely to rise more than 2 degrees Celsius, or 3.6 degrees Fahrenheit.

Gas pipes supplying Europe run right over swelling Yamal tundra which is deeply unstable to the release of underground methane.

The warm periods are linked with storms that penetrate into the Arctic from the Atlantic and Pacific oceans, and bring the temperature up by as much as 30 C in the middle of winter.

Pipes are built over bulging and unstable Arctic pingos prone to violent eruptions caused by 'thawing methane gas', as seen twice on the Yamal peninsula this year.

Scientists are divided about the impact of climate change on this particular break in Antarctica's ice shelf.

Coastal erosion occurring near Cape Blossom, outside of Kotzebue, Alaska.

Because this extreme heat will last for several more days, the floodwaters aren't going away anytime soon. The higher the truck, the better for residents evacuating flooded homes in the River Bend RV Park.

For the first time in 25 years, the Kluane Chilkat International Bike Relay has been cancelled - unexpectedly due to snow, 'black ice and slushy sections.'

Thanks to warming winters and thawing permafrost, Arctic soil microbes are churning out carbon dioxide well after the end of the growing season ends. This extra source of atmospheric carbon may accelerate a regional warming trend that is already twice as fast as the global average.

The fall of a climber into a crevasse highlighted this season's risky combination of crumbling snow bridges and splintered climbing teams.

A team of scientists had to abandon an expedition from Quebec City to Churchill, Man., on Sunday because of hazardous ice conditions caused by climate change.

The skiing season ended in Northern Lapland in mid-May, but the weather there is still so cold and snowfall so frequent that the Saariselkä resort will temporarily reopen its slopes, which are currently up to a metre deep in snow.

Hundreds of craters caused by methane explosions were discovered underneath Barents sea. Further research finds evidence that the violent explosions could happen again in the future.

As spring walrus hunting season gets underway, residents of St. Lawrence Island talk about sea ice changes and how they affect the village.

The annual ice melt in Canada's North is occurring earlier and earlier, and some researchers say that and other climate-related changes are affecting the mental health of populations in Inuit communities. CBC's Sabrina Fabian reports from Rigolet, Labrador.
