There’s a Wildfire Burning in West Greenland Right Now

It’s not just the American West and British Columbia burning up. A fire has sparked in western Greenland, an odd occurrence for an island known more for ice than fire. A series of blazes is burning roughly in the vicinity of Kangerlussuaq, a small town that serves as a basecamp for researchers in the summer to access Greenland’s ice sheet and… Read More

It shows that their direct influence on the climate has risen 140 percent since 1750, with 40 percent of that rise coming… Read More

Arctic Heat Is Becoming More Common and Persistent

Arctic Heat Is Becoming More Common and Persistent

The Arctic is a bastion of cold, blustery weather. But in the latest sign of how quickly changes are happening, new research published this week shows that the Arctic has seen more frequent bouts of warm air and longer stretches of mild weather. The new findings show that while warm snaps have occurred even as far as back as the 1890s, a massive… Read More

These Images Show Just How Big the Larsen C Iceberg Is

The Larsen C ice shelf has calved an iceberg after months of waiting and watching. With an area the size of Delaware and a volume of 277 cubic miles, its measurements boggle the mind. Even written comparisons don’t fully convey the hulking hunk of ice currently adrift in the Weddell Sea. After all, can you really imagine 463 million Olympic-sized … Read More

The Larsen C Iceberg Finally Broke Away. Now There’s a Trillion-Ton Iceberg Adrift

The Larsen C Iceberg Finally Broke Away. Now There’s a Trillion-Ton Iceberg Adrift

The inevitable moment of reckoning for the Larsen C ice shelf arrived. The growing rift that carved across one of the Antarctica Peninsula’s largest ice shelves reached its end, sending a 2,240-square mile iceberg spiraling into the sea. Welcome to the world, iceberg A68. The massive slab of ice, equivalent to the size of Delaware and large enough … Read More

The Larsen C Iceberg Is Expected to Have Company

The Larsen C Iceberg Is Expected to Have Company

It’s stressful being an iceberg hanging on by a thread. If you want proof, look no further than the Larsen C ice shelf. Just three miles stand between the crack that’s been cutting across the ice shelf since 2010 and open water. When it breaks through, it will cleave a trillion-ton iceberg. The stress of having a huge iceberg-to-be nearing its … Read More

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

The Arctic Has Been Crazy Warm All Year. This Is What It Means for Sea Ice

Melt season has begun in earnest in the Arctic. Scientists will spend the next few months watching sea ice turn into open water until the ice pack hits its nadir in early fall. The vagaries of the weather and ocean currents will play a major role in determining where this year’s Arctic sea ice minimum ranks. But the steady drumbeat of climate… Read More

The World Is on the Brink of an Electric Car Revolution

The World Is on the Brink of an Electric Car Revolution

The internal combustion engine had a good run. It has helped propel cars — and thus humanity — forward for more than 100 years. But a sea change is afoot that is forecast to kick gas-powered vehicles to the curb, replacing them with cars that run on batteries. A flurry of news this week underscores just how rapidly that change could happen… Read More
