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.

Researcher 'has a problem' with attributing West Antarctic Ice Sheet 'collapse' to human activity

From NASA JPL and Lamont-Doherty Earth Observatory, something that maybe journo-hacktivist Susanne Goldenberg should pay attention to before she writes another screed. Reports that a portion of the West Antarctic…

Claim: atmosphere heats the oceans, melts Antarctic ice shelf

From Penn State Underlying ocean melts ice shelf, speeds up glacier movement Warm ocean water, not warm air, is melting the Pine Island Glacier’s floating ice shelf in Antarctica and…

Untested claim: increased CO2 helps glacier ice to crack

From the Institute of Physics , something so overreaching I just can’t believe the Institute of Physics would put out a press release on it.  Where does one start with…

New ice loss unit – the New Jersey

From the University of Texas at Austin, an ice shelf as big as New Jersey might collapse, if conditions are right. Tipping points and all that. I suspect this gives…

Crack in the Antarctic!

From the University of Texas at Austin, a press release to tell us the ice shelves in the Antarctic peninsula are losing their grip and cracking a bit. That could…

RealClimate's Steig: Pacific SST's influencing Antarctic melt, no link to human causes demonstrated

WUWT readers may recall the Nature cover with this picture of Antarctica at left, followed by the subsequent falsification of the Antarctic warming claims made by Steig et al using…

NASA on the Antarctic Crack
