Arctic Stronghold of Seeds Flooded After Permafrost Melts

Arctic Stronghold of Seeds Flooded After Permafrost Melts

It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater … Read More

Waves Rippled Through Greenland’s Ice. That’s Ominous

Waves Rippled Through Greenland’s Ice. That’s Ominous

On its surface, the Greenland ice sheet is a vast expanse of seemingly immovable ice. But beneath the monotonous stretch of white, scientists have discovered evidence of waves rippling through one of its outlet glaciers and roiling its innards. The waves, observed during the two most intense melt seasons on record, sent an unprecedented cascade of … Read More

The Race to Understand Black Carbon’s Climate Impact

The Race to Understand Black Carbon’s Climate Impact

On a morning in September 2015, sterile, gray Arctic light filtered through a blanket of woolly clouds as Matt Gunsch and Tate Barrett parked their rented pickup truck on a dirt road and clomped in rubber boots down a long, icy boardwalk to their air-monitoring laboratory on the tundra. From the outside, the lab looked unglamorous — a dingy, white… Read More

Arctic Sea Ice Keeps Scraping the Bottom of the Barrel

Arctic Sea Ice Keeps Scraping the Bottom of the Barrel

The astounding transformation of the Arctic before our very eyes continues. Yet another month has passed with record low sea ice. This April merely tied April 2016 for the lowest extent on record, but it’s hardly reason to celebrate. The Arctic was missing 394,000 square miles of ice, with each day setting a record low or within 36,000 square … Read More

100 Days of Climate

Addressing climate change using sound science is crucial not just for the U.S., but for the world. Unfortunately, that appears unlikely over the next four years under the Trump administration, which has shown signs of being apathetic if not outright hostile to climate science and science-based policies to rein in carbon pollution. Trump has… Read More

Climate Change Altering the Arctic Faster Than Expected

Climate Change Altering the Arctic Faster Than Expected

Evidence continues to mount that climate change has pushed the Arctic into a new state. Skyrocketing temperatures are altering the essence of the region, melting ice on land and sea, driving more intense wildfires, altering ocean circulation and dissolving permafrost. A new report chronicles all these changes and warns that even if the world … Read More

The March For Science is Heading to Greenland

The March For Science is Heading to Greenland

Field research season is getting underway in Greenland. Scientists are racing to the island for the few months a year when the towering ice sheet is accessible. Despite the scramble to get as much research done as possible in such a tiny window, scientists will take a moment on Saturday to march in solidarity with thousands of other researchers… Read More

Icebergs Are Swarming Shipping Lanes in the Arctic

Icebergs Are Swarming Shipping Lanes in the Arctic

Like bees, icebergs sometimes roam in swarms. Unlike bees, icebergs can sink ships. It’s with that threat in mind that shipping companies are now avoiding parts of the North Atlantic, where an unusually large swarm of icebergs is making life miserable for captains on the high seas. Around 450 icebergs — defined as hunks of ice covering at least … Read More
