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

This is What It’s Like To Be a Young Climate Scientist

This is What It’s Like To Be a Young Climate Scientist

This year is proving to be a momentous one for the climate. There have been both wildly depressing and wildly hopeful milestones. On the downside, carbon dioxide passed the symbolic 400 parts per million threshold permanently (in our lifetimes anyways), the planet is going to have its hottest year on record for the third year in a row and a rash … Read More

Record Warmth Helps Shrink U.S. Carbon Emissions

Record Warmth Helps Shrink U.S. Carbon Emissions

Energy related carbon dioxide emissions hit their lowest point since 1991 during the first six months of 2016 because of mild weather, declining coal use and increased use of wind, solar and hydropower. By the end of the year, 2016 is expected to see the lowest level of energy related carbon emissions of any full year since 1992.… Read More
