Two East Antarctic ice shelves are releasing 70 ± 7 and 53 ± 9 billion metric tons of glacier meltwater into the ocean each year, according to a reconstruction published Sept. 11 in Nature…
Sunlight-driven chemistry in the top few meters of exposed Antarctic ice appears to change the greenhouse gases trapped inside it, Giyoon Lee and Jinho Ahn of Seoul National University and colleagues…
In July and August of 2013, as the snow line climbed uphill on Urumqi Glacier No. 1, a field team climbed up behind it. Five times over those two months they scraped the top centimeter of the surface…
At the edge of Antarctica, the geography that matters is the part nobody can see. Somewhere beneath the ice, the sheet stops resting on rock and begins to float. The shape of the ground it crosses on…
In the last week of May 2025, six people spent the better part of a day digging a hole in the snow in Wyoming's Wind River Range. Federal wilderness rules bar power tools, so the pit went down by…
Picture the winter sea ice around Antarctica not as a solid lid but as a shifting, fracturing crust. Cracks tear it open: narrow lines called leads and larger stretches of open water near the coast…
On the satellite maps that glaciologists have relied on for four decades, the ice streams of West Antarctica look fixed. Rivers of ice hundreds of kilometers long slide toward the Ross Sea between…
Once a month, someone walks into a private tunnel bored under the summit ridge of the Zugspitze, sprays salt water onto a line of steel electrodes fixed in the limestone, and sends an electric…
From a satellite's usual vantage, the seam where Alaska's boreal forest gives way to open tundra looks like a smudge, a gradual fade from green to brown across hundreds of miles. Up close it is…
A remotely operated underwater vehicle sent to the submerged front of a South Greenland glacier recorded large numbers of zooplankton, fish and other organisms that appear to respond to material shed…
A decade of measurements from an instrument tethered to the ice in Milne Fiord captured the draining of the last epishelf lake in the Canadian Arctic, which was lost when the Milne Ice Shelf…
The layer of soil that thaws each summer above permafrost has been getting deeper at most long-running monitoring sites since 2000, according to a study published Aug. 26th of this year in…
