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 Ice Sheet has begun to irretrievably collapse, threatening a 4-foot rise in sea levels over the next couple of centuries, surged through the news media…

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 may be the culprit for increased melting of other ice shelves, according to an international team of researchers. “We’ve been dumping heat into the atmosphere…

The WUWT Hot Sheet for September 12th, 2013

Climate models wildly overestimated global warming, study finds Can you rely on the weather forecast? Maybe not, at least when it comes to global warming predictions over short time periods. That’s the upshot of a new study in the journal Nature Climate Change that compared 117 climate predictions made in the 1990’s to the actual amount of…

Glacier in Antarctica does what glaciers do

From NASA, who has moved up from “Manhattans” to quarter states as a scale comparison unit: Antarctic Glacier Calves Iceberg One-Fourth Size of Rhode Island This week a European Earth-observing satellite confirmed that a large iceberg broke off of Pine Island Glacier, one of Antarctica’s largest and fastest moving ice streams. The rift that led…

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 notice to the press that we are switching from Manhattans to New Jerseys to measure ice loss in news releases and subsequent news stories. Then…

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 be tragic, except, well, sea ice in Antarctica is growing. And, there’s only a 40 year historical context for these observations. I just can’t too…
