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

New Tar Sands Impact on Climate, Air Quality Found

New Tar Sands Impact on Climate, Air Quality Found

In one of the first studies of its kind, scientists have found that tar sands production in Canada is one of North America’s largest sources of secondary organic aerosols — air pollutants that affect the climate, cloud formation and public health. The study, published Wednesday in the journal Nature, showed that the production of tar sands and … Read More

Greenland’s Melt Season Started Nearly Two Months Early

Greenland’s Melt Season Started Nearly Two Months Early

To say the 2016 Greenland melt season is off to the races is an understatement. Warm, wet conditions rapidly kicked off the melt season this weekend, more than a month-and-a-half ahead of schedule. It has easily set a record for earliest melt season onset, and marks the first time it’s begun in April. Little to no melt through winter is the norm … Read More
