Scientists nearly double sea level rise projections for 2100, because of Antarctica

Washington Post: Sea levels could rise nearly twice as much as previously predicted by the end of this century if carbon dioxide emissions continue unabated, an outcome that could devastate coastal communities around the globe, according to new research published Wednesday. The main reason? Antarctica. Scientists behind a new study published in the journal Nature used sophisticated computer models to decipher a longstanding riddle about how the massive, mostly uninhabited continent surrendered so much ice during...
In Antarctica, displaced penguins may be a sign of climate change

PRI: When researchers who study Adelie penguins in Antarctica returned to their study site to find most of the birds gone, the event made headlines. But the headlines were mostly wrong, according to the researchers. No one knows for sure what became of the missing birds, but Kerry-Jayne Wilson, one of the lead researchers and the author of a new paper about the event, wants to make one thing clear: I don't know where the 150,000 dead penguins came from. It didn't come from our paper, she says....
Penguins presumed dead after disappearing in Antarctica may have just moved on

Independent: News of their deaths prompted outcry worldwide, but the 150,000 Adelie penguins that were thought to have perished after they were landlocked by an enormous iceberg could still be alive, a scientist has claimed. Their colony shrank drastically after the B09B iceberg approximately the size of Rome floated in to their habitat close to Cape Denison, a rocky point at the head of Antarcticas, Commonweath Bay. Researchers from Australias University of New South Wales suggested they had died...
Antarctica could be headed for major meltdown

ScienceDaily: In the early Miocene Epoch, temperatures were 10 degrees warmer and ocean levels were 50 feet higher -- well above the ground level of modern-day New York, Tokyo and Berlin. It was more than 16 million years ago, so times were different. But there was one important similarity with the world we live in today: The air contained about the same amount of carbon dioxide. That parallel raises serious concerns about the stability of ice sheets in Antarctica, according to a study published in the Proceedings...

Antarctica could be much more vulnerable to melting than we thought
2016-02-23 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: In two new studies, scientists say that the vast ice continent of Antarctica seems to have given up tremendous volumes of ice -- even sprouting considerable plant life -- during an era over 10 million years ago when concentrations of atmospheric carbon dioxide dont seem to have been all that much higher than they are now. That period was known as the Miocene. And during its early and middle phases, between 23 and 14 million years ago, carbon dioxide concentrations are believed to have sometimes...
