Pine Island Glacier’s ice shelf is ripping apart, speeding up key Antarctic glacier

“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…

Antarctica wasn’t quite as cold during the last ice age as previously thought

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…

Claim: Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly

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…

Mass balance of the Antarctic ice sheet 1992–2016: reconciling results from GRACE gravimetry with ICESat, ERS1/2 and Envisat altimetry

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…

Claim: Evidence of Antarctic glacier’s tipping point confirmed for first time

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.

Claim: Antarctic Peninsula warming up due to heat in Tasman sea

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…

Atmospheric rivers help create massive holes in Antarctic sea ice

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…

On noes! Antarctic sea ice may not cap carbon emissions as much as previously thought

From the “that darned sea ice is messing up our model” department and MIT News. Study suggests sea ice blocks the flow of carbon both into and out of the…
