Greenland is Losing More Ice Than Scientists Thought

Greenland is Losing More Ice Than Scientists Thought

Bad news keeps flowing for the icy landscapes of the world. Rising temperatures are melting ice and sending it to the ocean, a process that is pushing sea levels higher and altering the landscape at both poles. The latest news comes from Greenland, where researchers have used high-tech satellite and GPS measurements to see how much mass the ice … Read More

These Images Show Near-Record Low 2016 Arctic Sea Ice

These Images Show Near-Record Low 2016 Arctic Sea Ice

Arctic sea ice is one of the grandaddy’s of climate indicators. And this grandaddy isn’t doing so good these days. Ice is disappearing at a quickening clip as rapidly warming air and water eats away at the briny, frozen mantle on the top of the planet. In the nearly four decades of satellite monitoring, sea ice has disappeared at a clip of 13.4 … Read More

Despite Major Melt, Arctic Sea Ice Will Miss Record Low

Despite Major Melt, Arctic Sea Ice Will Miss Record Low

As the sun begins its seasonal descent in the Arctic sky and temperatures drop, the summer melt of sea ice is slowing down. In the next few weeks, the span of the Arctic Ocean covered by ice will reach its annual low. But despite beginning the summer at unprecedentedly low levels, this year’s minimum won’t break the stunning record of 2012, expert… 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

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

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
