Since 1972, the giant island’s ice sheet has lost 11 quadrillion pounds of water.

Huerfano County says it's preparing for the worst when it comes to this year's flood season and it wants residents to be prepared.

Scientists from NASA and the National Oceanic and Atmospheric Administration have declared 2018 the fourth warmest year on record. It ranks behind 2016, 2017 and 2015, respectively. And it's only going to get warmer from here, they predict.

At least a third of the ice in the Himalayas and the Hindu Kush will thaw this century as temperatures rise, disrupting river flows vital for growing crops from China to India, scientists say.

The Arctic is expected to get warmer and wetter by the end of this century and new research says that could mean trouble for infrastructure in Inuvik.

Slik har Norge forandret seg. Sakte, nesten umerkelig.

Our hottest and coldest days are both getting warmer and tropical nights are becoming more common, a report says.

Climate change is causing more severe flooding around the country, and a disproportionate number of Native American communities are on the front lines.

From floods to fires, drought to coastal erosion, climate change is already having an impact on Canada's communities, landscapes and wildlife

The combination of abundant rain and snowfall and extremely warm mean annual air temperatures may have led to the destabilization of permafrost around lake margins. Rapid snow melt and high amounts of excess meltwater further promoted rapid lateral breaching at lake shores and consequently sudden drainage of some of the largest lakes of the study region.

Need a reason to be concerned about rising sea level? I've got eight.

The Federal Emergency Management Agency (FEMA) has disbursed $3.3 million to help Western Alaskans rebuild after ex-typhoon Merbok struck the coast a month ago.

Authorities try to talk down a wave of panic buying in B.C. stores as washed-out roads and rail lines snarl supply chains

Janice Moore, who lives along the West Channel, is worried about fuel contamination after intense flooding in Hay River, N.W.T., left multiple fuel containers strewn about her property. "You can smell the diesel smell and fuel smell," she said.

The Little Salmon Carmacks First Nation is warning spring melt could cause the tailings dam at the abandoned Mount Nansen mine in central Yukon to overflow or breach, which would send a toxic slurry into the environment.

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.

The temporary repairs would consume about 60% of the town’s annual budget for contract work on roads, a Girdwood official said.

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

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.

Climate change and warmer conditions have altered snow-driven extremes and previous studies predict less and slower snowmelt in the northern United States and Canada. However, mixed-phase precipitation—shifting between snow and rain—is increasing, especially in higher elevations, making it more challenging to predict future snowmelt, a dominant driver of severe flooding. Researchers at the University of New Hampshire took a closer look at previous studies, and because geographical areas respond differently to climate change, they found future snowmelt incidences could vary greatly by the late 21st century. Snowmelt could decrease over the continental U.S. and southern Canada but increase in Alaska and northern Canada resulting in larger flooding vulnerabilities and possibly causing major societal and economic consequences including costly infrastructure failures.
