Average number of days with heavy rain or snow across Canada has been outside norm since spring 2013
A team of scientists presented data on Tuesday suggesting that even as the state of Alaska has warmed up extremely rapidly in recent years, snowfall in the iconic Denali National Park has increased dramatically during the era of human-driven global warming.
On a remote Alaskan sandbar, under the watchful eye of a devoted scientist for more than four decades, climate change is forcing a colony of seabirds into a real-time race: evolve or go extinct.
A study of rock avalanches in the western part of Glacier Bay National Park and Preserve found that the likelihood of large slides covering about 2 square miles has at least doubled in the last five years.
Climate warming is likely to bring more episodes of heavy rain, above-freezing winter thaws and scorching hot summer days in the coming decades, says a study by scientists at the University of Alaska Fairbanks.
Warm periods are bringing the temperature up by as much as 30 C in the middle of winter
The latest research shows that diminishing Arctic sea ice caused by climate change is forcing some species to travel further to find food or look for alternative food sources.
Sixty years ago, around the time when Matthew Rexford's father's father was turning the ground to build his own ice cellar as a proud whaling captain, there were 12 of these such cellars in Kaktovik. Today there is only one left.
Climate change could cause another 4 million square kilometers, or about 1.5 million square miles, of permafrost to disappear with every additional degree Celsius, or 1.8 degrees Fahrenheit, of warming, a new study suggests.
This visualization begins by showing the dynamic beauty of the Arctic sea ice as it responds to winds and ocean currents. Research into the behavior of the Arctic sea ice for the last 30 years has led to a deeper understanding of how this ice survives from year to year. In the animation that follows, age of the sea ice is visible, showing the younger ice in darker shades of blue and the oldest ice in brighter white. This visual representation of the ice age clearly shows how the quantity of older and thicker ice has changed between 1984 and 2016.
A recent study shows that polar bears' mercury levels are declining as melting ice drives them onshore. But is it all good news? Read on.
Ice skating on Goodacre Lake in Beacon Hill Park was a common winter pleasure in the past. Generations of Victorians glided under the Stone Bridge on natural ice and circled the islands in the moonlight.
As the climate warms and Arctic sea ice retreats and gets thinner, more light is getting through. “Since marine zooplankton respond to the available light, this is also changing their behaviour – especially how the tiny organisms rise and fall within the water column,” the AWI said in a news release on their website.
Winter drownings become more common on warmer days or when rain has fallen on snow, leaving the ice thinner, weaker, and less stable.
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.
The Inuit are famous for their ability to survive extreme conditions, having inhabited the Arctic for millennia. But as the ice recedes, this hard-earned knowledge is being lost.
Experts use measuring sticks and tanks in regular intervals to monitor snowfall as this season’s total approaches an all-time high.
For the residents of Tuluksak, breakup means that they will once again be losing their source of running water.
The city told owners their buildings should not be occupied until snow is removed if they have a roof at risk of collapse.
A changing climate threatens the pastime of outdoor ice hockey around the world and in Finland.
