It’s a first! Glenn, Gareth and John manage to record a show that clocks in at under an hour — but it’s still packed with interesting stuff. We’ve got news about a new Australasian hockey stick — a paleoclimate reconstruction that demonstrates that the last three decades are the warmest in the last 1,000 years, a look under an Antarctic ice shelf, more methane research, and good news from Greenland. John Cook from Skeptical Science looks at the misuse of temperature records from the Sargasso Sea, and we look at electric planes and boats and the latest version of the solar “leaf”. And… Glenn announces his imminent move to the UK, but never fear, the show will go on — just as soon as he sets up his computer in London (which might be a couple of months).
News & commentary: [0:04:15]
Scientists from the University of Melbourne used 27 natural climate records, including tree rings, corals and ice cores to create the first large-scale temperature reconstruction for the region over the past 1000 years.
Methane held underground by caps of Arctic ice is bubbling out as a warming climate causes those caps to melt, researchers report in the journal Nature Geoscience.
Potential Instability in West Antarctic Ice Sheet from Newly Discovered Basin Size of New Jersey:
The Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet: press release.
Sea-level rises ‘may not be as high as worst-case scenarios have predicted’: Guardian.
Store Glacier at Extreme Ice Survey. (Jason Box tells me that he will be posting images of his Greenland fieldwork to a public Picasa page when he gets somewhere with reasonable bandwidth).
Debunking the sceptic [37:15]
John Cook from skepticalscience.com talks about sceptic misuse of a Sargasso Sea temperature record, and Mark Boslough and Lloyd Keigwin debunking the cherries picked in the process…
EV Pioneer Plans to Recreate Lindbergh’s Flight in Electric Airplane, with pix of the flying batteries here. (Plus: an extra solar plane story not featured in the show — another approach to solar-powered flight, aiming to fly from Switzerland to Morocco).
