Arctic Sea Ice Sees Strange Cold Season Retreat

Arctic Sea Ice Sees Strange Cold Season Retreat

The Arctic is missing a chunk of sea ice the size of Mexico. While fall ushers in the season of sea ice growth, November saw a brief retreat that was virtually unprecedented in nearly 40 years of satellite records, according to data released Tuesday by the National Snow and Ice Data Center. That dip helped November set a record low for sea ice are… Read More

A Climate Denier is Leading the NASA Transition

A Climate Denier is Leading the NASA Transition

Scientists and policy watchers have been sounding the alarm bell that NASA’s climate work could be in jeopardy ever since Donald Trump’s election last month. That’s due in large part to some of his advisors saying the agency should be focused on space exploration and not wasting money observing the earth. But the alarm started ringing louder last … Read More

Odd Rifts in Antarctic Ice Could Mean ‘Sayonara, Glacier’

Odd Rifts in Antarctic Ice Could Mean ‘Sayonara, Glacier’

In August of 2015, a large iceberg broke off from the floating section of Antarctica’s massive Pine Island Glacier. While such an event is part of the natural life cycle of glaciers, this one was precipitated by an unusual rift in the middle of the ice that could point to a new mechanism for the collapse of this and potentially other glaciers … Read More

The Arctic is a Seriously Weird Place Right Now

The Arctic is a Seriously Weird Place Right Now

The sun set on the North Pole more than a month ago, not to rise again until spring. Usually that serves as a cue for sea ice to spread its frozen tentacles across the Arctic Ocean. But in the depths of the polar night, a strange thing started to happen in mid-October. Sea ice growth slowed to a crawl and even started shrinking for a bit. Intense … Read More

Here’s How Much CO2 Will Make the Arctic Ice-Free

Here’s How Much CO2 Will Make the Arctic Ice-Free

For every round-trip transatlantic flight or just two months of a home’s electricity use, 30 square feet of Arctic sea ice is lost, according to a new study that lays out in the simplest possible terms the relationship between heat-trapping greenhouse gas emissions and the precipitous decline of sea ice. The further accumulation of 1,000 gigatons… Read More

Warm Temps Slow Arctic Sea Ice Growth to a Crawl

Warm Temps Slow Arctic Sea Ice Growth to a Crawl

A strange thing is happening in the Arctic. After dipping to its second-lowest extent on record in September, sea ice has struggled mightily to rebound in October. Freakishly mild weather coupled with a warmer than normal ocean are in large part responsible for the great sea ice slowdown of 2016. It’s just the latest piece of evidence that 2016 is … Read More

Tibet Just Had Another Massive Ice Avalanche

Tibet Just Had Another Massive Ice Avalanche

An ice avalanche stretching 3.7 miles and burying the land in up to 98 feet of ice is weird. A second one in almost the exact same location just a few months later is essentially unheard of. And yet that’s exactly what happened in a remote corner of Tibet in late September, when a second massive jumble of ice and rock ripped across the landscape … Read More

Warm Ocean Water Takes Toll on Antarctica’s Glaciers

Warm Ocean Water Takes Toll on Antarctica’s Glaciers

It has become increasingly clear in recent years that ocean waters are eating away at the undersides of the ice shelves that fringe Antarctica and buttress its many glaciers. A new study released Tuesday has found that hundreds of feet of ice have been lost from the bottoms of a few of these ice shelves and glaciers in a region of the continent… Read More
