Back-to-back Arctic storms can double sea ice loss
12+ hour, 4+ min ago (663+ words) Scientists have found that Arctic cyclones become especially destructive when several strike one after another. These storm clusters cause about twice as much sea ice loss as isolated cyclones, with impacts that persist roughly two and a half times longer....
Thawing Permafrost Is Releasing Carbon, but Something Unexpected Happens
16+ hour, 23+ min ago (797+ words) Much of the ancient carbon released from thawing Arctic permafrost appears to end up trapped in seabed sediments rather than quickly returning to the atmosphere. The Arctic’s frozen ground holds an enormous reservoir of organic carbon. As permafrost thaws and…...
Bam! Prefab reef installed 14 miles off Naples creates instant habitat
3+ day, 12+ hour ago (556+ words) A massive cobalt blue barge floats on the surface of the Gulf as seabirds soar overhead while classic, low-hanging summertime clouds drift to the south. The Maratha II out of Orange Beach, Alabama on the morning of Sept. 2 is facing…...
The Deepest Dive Ever Made In American Waters
1+ day, 1+ hour ago (347+ words) Limiting Factor is a two-person Triton 36000/2 submersible rated to 11,000 meters. Its pressure hull is a titanium-alloy sphere with walls 90 millimeters thick. Triton states that the sphere was machined to 99.933 percent of a true sphere. The crew sits inside that compact…...
Melting Arctic glaciers creating climate 'doom loop' by releasing ancient methane
2+ day, 21+ hour ago (885+ words) (Gabrielle Kleber / SWNS) Melting Arctic glaciers are creating a climate “doom loop” by flushing out ancient methane from rocks beneath the ice, reveals new research. The more glaciers melt, the more of the greenhouse gas they are likely to release…...
Up-Close: The World’s Most Terrifying Glacier
1+ day, 11+ hour ago (879+ words) “Thwaites demise is inevitable” (Inside Antarctica’s Doomsday Glacier, PBS, August 19th, 2026). Aboard the South Korean icebreaker Araon: “This is Thwaites, a glacier on the edge of Earth, teetering on the edge of collapse – the most consequential glacier on the planet. No…...
A 76-Square-Kilometer Iceberg Broke Free From Greenland’s Glacier, But The Biggest Surprise Came After It Drifted Away
1+ day, 2+ hour ago (633+ words) A record-sized iceberg separated from Greenland’s Petermann Glacier, creating one of the Arctic’s most unusual ice events in years. Researchers followed its path as the massive iceberg moved into open waters. A giant iceberg covering 29 square miles broke away from…...
Norway's biggest quake in 100 years set off a glacier-burying avalanche on thawing ground
1+ day, 13+ hour ago (384+ words) A powerful earthquake on March 10, 2025, did more than shake Jan Mayen, a remote Norwegian island in the Arctic Ocean. It also unleashed a massive rock avalanche that buried a large section of a glacier, and researchers say rising temperatures likely…...
How melting Arctic glaciers is creating a climate ‘doom loop’
2+ day, 10+ hour ago (111+ words) Taking water samples from a glacial river on Svalbard. (Gabrielle Kleber via SWNS) Melting Arctic glaciers are creating a climate "doom loop" by flushing out ancient methane from rocks beneath the ice, reveals new research. Dr. Gabrielle Kleber during Svalbard…...
Shrinking sea ice during heat waves helps polar seas absorb more CO2, study finds
1+ day, 14+ hour ago (477+ words) With less sea ice blocking sunlight, more light reaches surface waters and encourages phytoplankton growth. Marine heat waves are often seen as another sign that the planet's natural defenses are faltering. But a new global analysis suggests that, in some…...
