From 1979-2018 East Antarctica cooled -0.70°C/decade (-2.8°C), West Antarctica cooled -0.42°C/decade (-1.68°C), but the Antarctic Peninsula warmed 0.18°C/decade (0.72°C). Thus, as a whole, the Antarctic continent has...

"The recent changes in speed are not due to melt-driven thinning; instead they're due to the loss of the outer part of the ice shelf," Joughin said. "The glacier's speedup is not catastrophic at this point. But if the rest...

An international team of scientists, led by Oregon State University's Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over central East Antarctica...

Some other researchers suggest that ice cliffs in Antarctica might not collapse as quickly as those in Greenland. But given their size and current rates of warming – far faster than in the historic record – what if they...

Die kalte Sonne brings up the question: Why were these earlier studies – many based on observations – ignored by Rosier et al? “Hard to believe they were,” says the Die kalte Sonne video report...

To add to that picture, this study found that elephant seals migrated to the Victoria Land Coast in the Ross Sea about 8000 years ago, as the region became warmer, and stayed there till about 1000 years ago when sea ice returned.

During 1992–2016, the AIS changed from a positive mass balance of over 100 Gt a−1, which was reducing sea-level rise by 0.3 mm a−1, to a state of balance close to zero by 2014. The mass balance successively changed...

He added: "The possibility of Pine Island Glacier entering an unstable retreat has been raised before but this is the first time that this possibility is rigorously established and quantified.

Heating of the Tasman sea warms up the climate of Antarctic Peninsula via changes in wind patterns, new study by Japanese and Australian scientists shows RESEARCH ORGANIZATION OF INFORMATION AND…

PENN STATE Research News When a block of ice the size of Houston, Texas, broke off from East Antarctica’s Amery Ice Shelf in 2019, scientists had anticipated the calving event,…

That meltwater forms strong coastal currents and ocean fronts, and those currents are impacted by winds, tides, and break down if they become unstable...

Guest Post by Renee Hannon Introduction This post examines CO2 data collected in Antarctic firn and its journey as firn transitions to ice where CO2 is eventually trapped in bubbles.…

Antarctica's next deep ice core, drilling down to ice from 130,000 years ago, will be carried out by a multi-institutional U.S. team at Hercules Dome, a location hundreds of miles from today's coastline and a promising site...

Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to Rutgers...

Some years ago, relating to a project I was carrying out, I asked the Max Planck Institute and Cambridge University –both experts in this field-if it were possible that Antarctic ‘ozone hole’ -actually a ‘thinning’...
