14+ hour, 37+ 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…...

4+ day, 1+ hour ago   (386+ words) These new findings could help scientists adapt crops to dry environmental conditions in the future. By analyzing the genomes of three species in the genus Clusia, the scientists traced how genome duplication followed by genetic restructuring helped produce a wide…...

4+ day, 9+ hour ago   (326+ words) A giant 29 square mile iceberg broke from Greenland’s Petermann Glacier and survived a collision with Joe Island that might have shattered a more fragile berg....

1+ week, 2+ hour ago   (866+ words) A mountain of loose rock in Utah hides enough ice to fill 600 Olympic swimming pools, revealing that some of the state’s largest frozen water reserves are almost invisible from the surface. Unlike conventional glaciers, which expose broad expanses of ice,…...

1+ week, 1+ day ago   (739+ words) From tiny glass beads and a map of the Moon to Mercury, a new study uses an indirect method to determine the silicon dioxide content of Mercury’s surface. Mercury’s surface appears to contain substantially less silicon dioxide than researchers previously…...

1+ week, 2+ day ago   (110+ words) A tropical warming event helped drive record snowfall and a temporary 695-billion-ton ice gain in East Antarctica without reversing long-term Antarctic ice loss....

1+ week, 3+ day ago   (782+ words) A Manhattan-sized ice island has broken free from Greenland’s Petermann Glacier, and scientists say even bigger breaks may be coming. Europe’s Copernicus Sentinel-1 mission has documented a major breakup at Petermann Glacier in northwest Greenland, where a 76 sq km portion…...

1+ week, 5+ day ago   (554+ words) Carbon released by the Industrial Revolution has left a chemical fingerprint nearly everywhere scientists looked in the North Atlantic, including waters thousands of feet below the surface. Scientists have traced carbon from fossil fuel emissions deep into the North Atlantic…...

1+ week, 6+ day ago   (772+ words) Thousands of enormous whales are turning the waters off East Greenland into an immense feeding ground that barely existed a generation ago. Fin whales, humpback whales, and common minke whales now gather along a coastline where all three were once…...

3+ week, 1+ hour ago   (479+ words) Melting permafrost 304 million years ago may have released vast amounts of carbon into the atmosphere. A warming episode 304 million years ago may show how a relatively small climate shift can trigger much larger changes. Researchers studying the event found evidence…...
