Antarctic Ice Sheet to melt, raise sea levels by 8.5 feet even under Paris Agreement

Antarctic Ice Sheet to melt, raise sea levels by 8.5 feet even under Paris Agreement

World
Sept. 23 (UPI) -- The Antarctic Ice Sheet will suffer irreversible ice loss raising ocean levels by 8.5 feet even if the world meets global warming goals laid out by the Paris Agreement on Climate change, scientists said in a report published Wednesday. The analysis determined there are a number of temperature thresholds above pre-industrial levels that will ultimately lead to increasing sea levels if the world's nations don't rein in emissions and global warming. Advertisement The study, published Wednesday in the journal nature, was conducted by researchers at the Potsdam Institute for Climate Impact Research and the University of Potsdam in Germany, Columbia University in New York City, and Stockholm University in Sweden. The researchers determined that if global warming is maintained ...

Dozens of scientists are sitting in quarantine, waiting for permission to sail forth and capture a crucial moment in the polar calendar that’s essential to their year-long Arctic research missionBy FRANK JORDANS Associated PressMay 10, 2020, 8:03 AM4 min read4 min readShare to FacebookShare to TwitterEmail this articleBERLIN -- They prepared for icy cold and trained to be on the watch for polar bears, but a pandemic just wasn't part of the program. Now dozens of scientists are waiting in quarantine for the all-clear to join a year-long Arctic research mission aimed at improving the models used for forecasting climate change, just as the expedition reaches a crucial phase. For a while, the international mission looked like it might have to be called off, as country after country we...
Climate change: Greenland ice melt ‘is accelerating’

Climate change: Greenland ice melt ‘is accelerating’

Science
Media playback is unsupported on your device Greenland is losing ice seven times faster than it was in the 1990s. The assessment comes from an international team of polar scientists who've reviewed all the satellite observations over a 26-year period. They say Greenland's contribution to sea-level rise is currently tracking what had been regarded as a pessimistic projection of the future.It means an additional 7cm of ocean rise could now be expected by the end of the century from Greenland alone.This threatens to put many millions more people in low-lying coastal regions at risk of flooding. It's estimated roughly a billion live today less than 10m above current high-tide lines, including 250 million below 1m. "Storms, if they happen against a...

2 insect species classified as threatened as glaciers melt

Technology
Federal wildlife officials say the continued existence of two species of insects is in doubt because the glaciers and year-round snowfields they depend on are melting awayBy MATT VOLZ Associated PressNovember 20, 2019, 10:16 PM3 min read The continued existence of two species of insects is in doubt because climate change is melting away the glaciers and year-round snowfields they depend on, U.S. wildlife officials said Wednesday. The western glacier stonefly and the meltwater lednian stonefly found in the northern Rocky Mountains will be protected as threatened species under the federal Endangered Species Act. U.S. Fish and Wildlife Service officials said. “We recognize the fact that this species is not doing well,” agency spokeswoman Jennifer Koches said. “The primary threat to the habita...

Images reveal Iceland’s glacier melt

Science
A photography project has highlighted the extent of ice loss from Iceland's glaciers.A team from Scotland and Iceland compared photographs taken in the 1980s with present-day drone images.They focused on the south side of the Vatnajökull ice cap, which covers about 7,700sq km of land. Dr Kieran Baxter, from the University of Dundee, said: "We saw a staggering difference in a very short amount of time."
