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). Full show notes up at http://theclimateshow.com.

We learned a lot this week, as Professor Keith Hunter of the University of Otago, one of the world's leading ocean chemists, gave us a masterclass on ocean acidification and what it means for the future of the oceans. Plus we discuss Australia's new carbon tax, green growth campaigns in New Zealand, why China's aerosols may have been doing us a favour and why cleaning them up might unleash more warming, and climate models having trouble with rapid climate events. On the solutions front we look at a tiny electric aeroplane setting a new speed record and a solar initiative in NZ. No John Cook in this show, but he'll be back soon.

Special guest on this week's show is Dr James Hansen, director of NASA's Goddard Institute of Space Studies and perhaps the best-known climate scientist in the world — the man who put the 350 in 350.org and a forceful advocate for leaving coal in the ground. We caught up with him during his recent NZ tour, and grabbed an interview during his whirlwind visit to Canterbury University (thanks Bronnie!). John Cook's back from the tour launching his new book Climate Denial: Heads In The Sand, and talks about his experiences on the road as well as debunking the "CO2 lags warming" myth. Plus the Australian Climate Commission's new report, The Critical Decade, Britain's ambitious new carbon targets, and a couple of new solar power initiatives.

Ozone is the centrepiece of our show this week, with Dr Olaf Morgenstern of NIWA's Central Otago atmospheric science lab (celebrating its 50th birthday at the moment) explaining the ins and outs of the ozone holes north and south, and their impacts on the climate system. Plus tornadoes, heatwaves, UN negotiations at an impasse, more melting in the Arctic, airships, see-through solar cells and Google's solar towers. No John Cook this time — he's been too busy launching his book (good luck with that John!). For more show notes and links head to http://www.theclimateshow.com

Glenn says he thinks this show’s “a cracker” (but he always says that), and despite the lack of a special star guest — though with the help of assorted luminaries from the Climate Futures Forum (David’s Karoly and Frame, Robert Gifford and Erik Conway –) we cover a huge range of issues, from Jim Hansen’s upcoming visit to NZ, the climate talks in Bangkok and Arctic ice, to why we need to think about our carbon budget, and why a trillion tonnes of the stuff might be a tad too much. John Cook joins us to discuss why there really is a scientific consensus on the reality of climate change and its causes, and in the solutions section we look at new developments in battery technology.

Meltdown in the treacle factory (Glenn's PC) means that episode 10 of everybody's favourite Climate Show is only available in full by podcast. We've resurrected the video of our interview with David Suzuki, the great Canadian environmentalist and campaigner (above), but for the full goodness -- a great climate change graphic, Russian heatwave analysis, thoughts on climate communication, John "Skeptical Science" Cook introducing the new politicians' myths section on SkS and explaining the #1 skeptic delusion (no, it isn't the sun wot dun it), plus whole stack of solutions -- tidal power, electric motorbikes, biochar for pasture and artificial photosynthesis -- you'll have to listen to the audio version (link below). That means you'll have to do without the graphics we so lovingly describe, but... they're all in the show notes http://www.theclimateshow.com (Back, with luck with pictures, in two weeks).

With the terrible events in Japan uppermost in everyone’s mind, this week’s Climate Show goes nuclear, examining the prospects for the future of nuclear energy with Professor Barry Brook from the University of Adelaide. John Cook looks at what the tropical troposphere hot spot really means, and Gareth and Glenn look at mass loss from the Greenland and Antarctic ice sheets, a record ozone hole over the Arctic, and review last winter’s climate numbers.

The Climate Show returns with a packed show, featuring one of the world’s best known climate scientists, NZ-born, Colorado-based Dr Kevin Trenberth — star of the Climategate “where’s the missing heat” emails. He’s been in New Zealand to visit family (experiencing the Christchurch quake in the process) and to attend a conference, and his comments on the state of our understanding of climate change should not be missed. John Cook of Skeptical Science returns with his new short urls and an explanation of why declines have never been hidden, and Gareth and Glenn muse on Arnie “Governator” Schwarzenegger riding to the rescue of climate science, cryospheric forcing and carbon cycle feedbacks from melting permafrost, and a new paper that suggests that current policies are pointing us towards extremely dangerous climate change. All that and hyperbranched aminosilica too...

A very wide ranging Climate Show this week, with Dr Philip Boyd of NIWA and Otago University explaining why fertilising the oceans to soak up more carbon is not likely to be our "get out of jail free" card, John Cook of Skeptical Science introducing the new Monckton Myths section of the site, plus interesting new papers on Atlantic warming adding to the Arctic's problems, an accurate prediction of last year's Pakistan flooding, and the coolest 1970s Datsun on the planet. A show about climate change presented by gareth Renowden from http://www.hot-topic.co.nz and Glenn Williams from http://www.glennwilliams.co.nz. For more http://www.theclimateshow.com

The Climate Show returns with the first show of the new year, and it’s a cracker. Our guest is Dr Brad Bass, an expert in “green” roofing who joined Glenn in the Auckland studio to discuss the many advantages of growing things (even trees!) on our buildings. John Cook from Skeptical Science gives us an eye-witness account of the Queensland flooding, and explains the climate and weather background to the event. We also discuss last year’s record setting temperatures, the fakery of Don Easterbrook, and an interesting breakthrough in solar power technology.

Our last show for 2010, and it's over an hour of podcast/video goodness: featuring Peter H Gleick of the Pacific Institute discussing the news from the Fall AGU conference in San Francisco last week, John Cook discussing how we work out how sensitive the climate system is to the addition of heat, plus a roundup on Cancun, how French vignerons are looking to old vines to help them adapt to a warming climate, and London's black cabs set to go electric. A show about climate change presented by gareth Renowden from http://www.hot-topic.co.nz and Glenn Williams from http://www.glennwilliams.co.nz.

Climate talks heat up in Mexico, snow blankets Britain and much of Europe, and The Climate Show is at the heart of the action. Glenn and Gareth set the scene for COP16 in Cancún and then interview Oxfam NZ’s Barry Coates at the conference to find out how things are shaping up. Gareth explores the link between Arctic climate change and cold winter weather in Western Europe, John Cook debunks that favourite sceptic myth — that the world’s cooling — and we look at the potential for nuclear power to provide part of the solution to decarbonising the power economy.

Cracking episode of The Climate Show this week, featuring a must-listen interview with Naomi Oreskes discussing the background to her book Merchants of Doubt. The people who attacked her 2004 paper on the scientific consensus about global warming didn't know what they were letting themselves in for. Also in the show: excellent infographics, Arctic warming bringing colder winters to the northern hemisphere, European biofuels, John Cook of Skeptical Science discusses the new Twitter bot that auto argues with denier tweets, electric cars again, and steady state economics. Not wide-ranging at all, really. A show about climate change presented by gareth Renowden from http://www.hot-topic.co.nz and Glenn Williams from http://www.glennwilliams.co.nz.
