Climate Change Could Put Tiny Krill at Big Risk

Climate Change Could Put Tiny Krill at Big Risk

They may be small, but krill — tiny, shrimp-like creatures — play a big role in the Antarctic food chain. As climate change warms the Southern Ocean and alters sea ice patterns, though, the area of Antarctic water suitable for krill to hatch and grow could drop precipitously, a new study finds. Most Antarctic krill are found in an area from the … Read More

This Is What the Ice-Free Northwest Passage Looks Like

This Is What the Ice-Free Northwest Passage Looks Like

An ice-free Northwest Passage was once the stuff of legend. But it’s now becoming the norm thanks to global warming, and commercial freighters to luxury cruise ships are racing to turn a profit off the newest frontier on earth. An image published by NASA Earth Observatory shows a nearly ice-free path from the North Atlantic to the Pacific… Read More

Greenland Melt Could Expose Hazardous Cold War Waste

Greenland Melt Could Expose Hazardous Cold War Waste

When the U.S. military abandoned Camp Century, a complex of tunnels dug into the ice of northwest Greenland, in the mid-1960s, they left behind thousands of tons of waste, including hazardous radioactive and chemical materials. They expected the detritus would be safely entombed in the ice sheet for tens of thousands of years, buried ever deeper… Read More

Climate Change’s Fingerprints All Over California Wildfires

Climate Change’s Fingerprints All Over California Wildfires

Reports this week from the front lines of the Sand Fire in Southern California painted the scene as apocalyptic. The drought-fueled blaze was explosive, fast-moving and devastating, burning through 38,000 acres in the Santa Clarita Valley and forcing the evacuation of more than 10,000 homes. If the state’s wildfire season holds true to forecasts… Read More

Antarctic Peninsula Has Cooled, but Warming Will Win

Antarctic Peninsula Has Cooled, but Warming Will Win

For most of the latter half of the 20th century, the Antarctic Peninsula was one of the fastest-warming places on the planet, with serious repercussions for the local environment, including the spectacular disintegration of a millennia-old ice shelf, and global sea level rise. But a new study detailed Thursday in the journal Nature suggests … Read More

Oceans Eating Away at Yet Another Part of Antarctica

Oceans Eating Away at Yet Another Part of Antarctica

The Antarctic Peninsula is one of the fastest warming spots on the planet, and it was thought that the rising air temperature was driving the melt of the glaciers along its fringes. But it is actually warm ocean waters that are eating away at the ice along part of its western side, a group of scientists reported Thursday in the journal Science. The… Read More

Alberta Wildfires Costliest Disaster in Canadian History

Alberta Wildfires Costliest Disaster in Canadian History

The Fort McMurray wildfire, driven by drought and climate change, was the costliest natural disaster in Canadian history, ringing up $3.58 billion in losses, according to the Insurance Bureau of Canada. The wildfire, which ignited May 1 in eastern Alberta and was brought under control on July 5, forced Canada’s largest-ever evacuation. It scorched… Read More

Arctic Sea Ice Crashes to Record Low for June

Arctic Sea Ice Crashes to Record Low for June

The summer sea ice cover over the Arctic raced towards oblivion in June, crashing through previous records to reach a new all-time low. The Arctic sea ice extent was a staggering 100,000 square miles below the previous record for June, set in 2010. And it was 525,000 square miles below the 1981-2010 long-term average, according to the National … Read More
