Arctic Research Vessel Set Adrift to Study Sea Ice Decline

Arctic Research Vessel Set Adrift to Study Sea Ice Decline

A research vessel is adrift in the Arctic to study why sea ice is retreating faster than expected. Ice cover across the northern ocean fell to a new low last month, reaching just over 14.5 million sq kilometers (5.61 million square miles) at its winter peak, according to the National Snow and Ice Data Center, in Colorado. That was 130,000 sq… Read More

Thawing Permafrost Will ‘Seep, Not Explode’ CO2

Thawing Permafrost Will ‘Seep, Not Explode’ CO2

The Arctic holds more than a trillion tons of carbon, locked in the frozen soil known as permafrost. That’s more than twice as much carbon as there is in the atmosphere itself, according to a 2013 report from the National Academy of Sciences. And as the climate warms under its growing blanket of human-generated greenhouse gases, thawing permafrost … Read More

Arctic Sea Ice Hits Record Low Winter Peak

Arctic Sea Ice Hits Record Low Winter Peak

It’s official: When the sea ice that blankets the Arctic Ocean hit its peak it yearly peak on Feb. 25, and maximum area it achieved was a record low, the National Snow & Ice Data Center announced Thursday. Warm temperatures in parts of the polar regions kept sea ice levels depressed, and also contributed to the winter peak occurring much earlier… Read More

Arctic Sea Ice Dwindling Toward Record Winter Low

Arctic Sea Ice Dwindling Toward Record Winter Low

While balmy hints of spring melt piles of snow in the eastern U.S., the impending end of winter marks peak season for Arctic sea ice. But this year, that winter maximum area is currently on track to hit a record low since satellite records began in 1979. What that low-ice mark means for the spring and summer melting seasons is unclear, but the… Read More

Arctic Sea Ice Is Getting Thinner, Faster

Arctic Sea Ice Is Getting Thinner, Faster

While the steady disappearance of sea ice in the Arctic has been one of the hallmark effects of global warming, research shows it is not only covering less of the planet, but it’s also getting significantly thinner. That makes it more susceptible to melting, potentially altering local ecosystems, shipping routes and ocean and atmospheric patterns.… Read More

Sea Ice Still Declining, Despite Antarctica’s Gains

Sea Ice Still Declining, Despite Antarctica’s Gains

When Antarctica grabbed headlines last year because of record-high sea ice levels circling the southernmost continent, it created confusion. Its increase was so at odds with the trend of dwindling sea ice, particularly in the Arctic, that it prompted those skeptical of the science of climate change to suggest it meant ocean ice is not disappearing.… Read More

Cold Air Invasion Coming: What’s the Role of Warming?

Cold Air Invasion Coming: What’s the Role of Warming?

Get ready for the invasion — of cold air. Temperatures are set to drop to levels that are low even for the middle of winter across the eastern U.S. starting Thursday and again over the weekend as Arctic air makes repeated surges southward. Temperatures Sunday morning could be below freezing as far south as Florida. This pattern may sound familiar t… Read More

Here’s What the Inside of Greenland Looks Like, in 3D

Here’s What the Inside of Greenland Looks Like, in 3D

Want to know what the inside of an ice sheet looks like? A new 3D map and animation of the Greenland ice sheet lets researchers peer into the layers of ice laid down over millennia and see how they have been warped as they flow over time and are put under pressure as newer layers accumulate above. This will help them better understand how Greenland… Read More
