A UM study has found that tidal flooding has leaped by 400 percent in the last ten years thanks to climate change.

If you're wondering why British Columbia experienced such a mild winter and early spring, you could maybe blame it on a mysterious "blob" of warm water in the Pacific Ocean.

Since 1976, the distribution of molting Black Brant ( Branta bernicla nigricans ) on the Arctic Coastal Plain has shifted from inland freshwater lakes to coastal marshes, such as those occupying the Smith River and Garry Creek estuaries.

By century's end, rising sea levels will turn the nation's urban fantasyland into an American Atlantis. But long before the city is completely underwater, chaos will begin

At risk from surging storm waves and floods, Alaska's coastal villagers are dealing with the immediate consequences of climate change -- threats to their health, safety and even their ancestors' graves.

While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing disproportionately to a phenomenon known as "thermokarst," the abrupt collapse of ice-rich permafrost as a result of thawing.

By Saturday, the East Fork fire had grown to just over 108,000 acres but triggered no mandatory evacuations.

Ricky Wright points to the bank of a creek to show one way his hometown has been affected by climate change. Many banks have eroded or collapsed, and now some favorite fishing spots that were once on solid ground are reachable only by boat.

Climate change is causing infrastructure collapse and increased polar bear encounters on Little Diomede Island, Alaska, as melting permafrost undermines buildings and ice loss affects wildlife behavior.

Scientists from the Russian Academy of Sciences hypothesize that as the melting of the permafrost becomes more prevalent, so will the incidence of lung cancer.

The East Fork Fire in Western Alaska is the state's largest at the moment, estimated at more than 150,000 acres Thursday, and it's burning in a region where, just a couple decades ago, large fires would not have been expected.

IThe Great Whale River landslide, which happened about eight kilometres upstream from the Cree and Inuit villages of Whapmagoostui and Kuujjuarapik, was too far south to be caused by melting permafrost, and too deep to be caused by variations in the climate, says a landslide expert.

Projections show rising sea levels could cause Canada’s beaches to retreat inland, in extreme cases by as much as half a kilometre. The best option may be to stand back and let it happen.

After hitching a ride with humans, the species has colonised entire areas – and may be making the soil too fertile

In Yakutia, just a few meters separate summer from winter. There are places here where you can always build a snowman or taste fresh snowflakes.

New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years. Researchers combined air photographs from 1959 with field observations and state-of-the-art Light Detection and Ranging (LiDAR) data they collected in 2019 to understand how the Axel Heiberg Island landscape has evolved over a 60-year period

The need to diversify America's sources of graphite for electric vehicle batteries is driving the exploration of graphite mining projects in the United States, but concerns about the potential environmental impact and disruption to Indigenous communities remain.

Most of Alaska sits atop permafrost. But the ground is thawing, leading to unexpected and sometimes catastrophic outcomes — what scientists have called a “slow disaster.”

An amount of shoreline roughly the size of central Moscow now collapses into the sea every year.

Peatlands make up 3 percent of the earth’s landscape, yet absorb large amounts of carbon and harbor surprising biodiversity. Although peat bogs and fens are under increasing environmental threat, efforts to protect and restore these ecosystems are gathering momentum.
