I bagged a long sought after interview late last March, with Jeff Severinghaus (we have a connection I’ll explain tomorrow) of Scripps Oceanographic Institute.
Big Ice guy.

Jeff has some current research that I’ll be examining in coming videos, but as I spoke to Jeff he was just returning from a stay in Antarctica, so I asked him to summarize the best assessments.

Then of course, Covid hit, and my county in Michigan got devastated by a dam failure, and a whole load of the madness that is 2020 got in the way – but I finally came back around to this.
I matched Jeff’s clips with some from Richard Alley and Eric Rignot, well known to readers here. They spoke to me in New Orleans in 2017.

I had also talked to Susheel Adusumilli, also of Scripps, and I featured prominently the new work from Stef Lhermitte, of Delft University of Technology. Then I wrapped it with a summary from Twila Moon of the National Snow and Ice Data Center.
My Yale Climate Connections colleague Karen Kirk also had a pass at this research as well, her @CC_Yale piece:

Karen Kirk in Yale Climate Connections:


Climate researchers have long monitored ice sheet dynamics in the Amundsen Sea, focusing specifically on the Thwaites and Pine Island glaciers. The two sit side by side on Antarctica’s western peninsula covering an area roughly the size of nine U.S. coastal states stretching from Maine to Maryland. The two glaciers alone store ice that could account for about 4 feet (1.2 meters) of global sea level rise. Their “seaboard” location may help bring increased public attention and interest to the West Antarctic Ice Sheet, which if it melted could raise seas by a catastrophic 11 feet (3.4 meters).

An international effort led by the British Antarctic Survey recently published two papers (Hogan et al. and Jordan et al.) showing the first detailed maps of the seafloor at the edge of the Thwaites Glacier. The team mapped deep submarine channels that have been funneling warm water to this vulnerable location. High-resolution imagery pinpoints the pathways that allow warm water to undermine the ice shelf. Lead author Kelly Hogan of the British Antarctic Survey says the findings will improve estimates of sea-level rise from Thwaites Glacier. “We can go ahead and make those calculations about how much warm water can get under the ice and melt it,” Hogan said.

The other researchers, led by Stef Lhermitte, found stark visual confirmation of glacier disintegration using decades of time-lapse satellite imagery. Their work sheds light on the accelerating feedback process, wherein the rapid loss of ice is opening the door to ever-increasing melting.

Pope Francis’ visit to the US catalyzed the growing sense across the country, and across the globe, that climate change is, above all, a moral issue.

More and more scientists have realized that speaking to this moral dimension is far more persuasive than speaking the language of science and fact, as compelling as those are.  Most people simply respond better to an issue that is framed in moral terms.

The emerging story of what Exxon knew, and when they knew it, shows that the differences have never really been about the science questions – even the major oil companies knew the basic science truths 4 decades ago.  They simply made a moral decision that the lives of the next ten thousand generations of human beings were not as important as their own profits, and we are now witnessing the early impacts of that decision.

We’re going to have to have a contest to decide who looks craziest, – Monckton in this video, or Michelle Bachman on the cover of Newsweek.

An intrepid Kiwi reporter interviews Monckton on the dangerous topics of scientific fact, peer review, and, worst of all, brings up the hated John Abraham, whose mercilessly clinical dissection of Monckton finally revealed the full depth of the deception that is “Lord” Christopher Monckton.  (hear spittle-flecked rant here)

From the Description:

“One of the world’s most prominent, and controversial, climate change skeptics, has been in New Zealand this week. Lord Christopher Monckton, the 3rd Viscount of Brenchley, is here as part of a world lecture tour promoting climate change denial. Reporter Benedict Collins met Christopher Monckton in Auckland, and while the Viscount might not believe in global warming, it didn’t take long for the interview to heat up…”

For anyone that still hasn’t seen it, check out Monckton’s cure for AIDS – below…
