Thwaites glacier: Significant geothermal heat beneath the ice stream

Nevertheless, the heat flow could be a crucial factor that needs to be considered when it comes to the future of Thwaites Glacier. According to Gohl: “Large amounts of geothermal…

Climate adaptation sense. Part III: Dynamic Adaptation Policy Pathways

Best practice is to use 2 to 3 different teams with different perspectives/expertise in generating scenarios and evaluating scenarios of the other teams. I have been involved in three projects…

Study finds 24% of West Antarctic ice is now unstable

American Geophysical Union WASHINGTON–In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected,…

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…

Flashback: "Irreversible Collapse" of the West Antarctic Ice Sheet – from 1999

Guest post by David Middleton A Geological Perspective on the “Irreversible Collapse” of the West Antarctic Ice Sheet It’s “old” news, as this publication from 1999 shows us.

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…

New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account

I covered this story earlier today, and it was presented much differently in that press release. This press release takes a different tack. IMHO, it looks like a big “ooops”…

More 'ice free Arctic' claims – we've heard it all before

From the University of Massachusetts at Amherst, something we’ve heard before. For example this claim from 2008. Gotta love the use of props to show how climate tipping points work:…

Recent climate, glacier changes in Antarctica at the 'upper bound' of normal

From the University of Washington some walkback? In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the…

Claim: Fates of polar ice sheets appear to be linked

From the National Science Foundation – Press Release 12-115 Remote Siberian Lake Holds Clues to Arctic–and Antarctic–Climate Change Keys to climate change lie buried beneath “Lake E” in the Russian…

New paper using RADARSAT data: Antarctic ice shelves slowed down – "…have not been changed in a significant way in the past 12 years"

A new paper published May 15th in the the journal The Cryosphere utilizes 12 years worth of RADARSAT data to determine the rate at which some well known ice shelves in…

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…
