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

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

Scientists Urge Obama to Halt Oil Leasing in the Arctic

Scientists Urge Obama to Halt Oil Leasing in the Arctic

In a letter being delivered to the White House on Thursday, nearly 400 scientists from more than a dozen countries are urging President Obama to stop future oil and gas drilling in the Arctic Ocean because of the significant environmental and climate risks associated with further fossil fuels exploration there. “No new oil and gas leasing or … Read More

Melting Arctic Could Supercharge Climate Feedback Loop

Melting Arctic Could Supercharge Climate Feedback Loop

As global warming heats the Arctic, carbon dioxide emissions from melting permafrost could play a bigger role in worsening climate change than previously thought, according to a new study. Scientists have long considered methane emissions to be the biggest climate threat posed by thawing permafrost. Methane is more potent than carbon dioxide in … Read More

Wildfires Disrupt Oil Sands, Exposing Climate Risk

Wildfires Disrupt Oil Sands, Exposing Climate Risk

While importing oil from Canada has been controversial in the U.S., the devastating wildfires in Fort McMurray have served to underscore a larger issue: Natural disasters exacerbated by climate change can threaten major natural resources. The wildfires in Alberta forced tar sands production to be cut by about a third, or 800,000 barrels per day in… Read More

Arctic Sea Ice Breaks May Record . . . By A Lot

Arctic Sea Ice Breaks May Record . . . By A Lot

Arctic sea ice shrank to its fourth-lowest level in 50 years last month, setting a record low for the month of May and setting up conditions for what could become the smallest Arctic ice extent in history, according to National Snow and Ice Data Center data released Tuesday. “We didn’t just break the old May record, we’re way below the previous on… Read More

Warming Could Boost Carbon Storage in Alaska Forests

Warming Could Boost Carbon Storage in Alaska Forests

Climate change may dramatically increase carbon storage in Alaska’s temperate forests, possibly offsetting the climate impacts of melting permafrost and wildfires, new research from the U.S. Geological Survey shows. But there’s an asterisk: the study’s authors said their projections could be skewed by a lack of data on methane emissions from lakes… Read More
