Thin Ice: what polar science is telling us about climate

This guest post is by professor Peter Barrett, executive producer, and Suze Keith, marketing advisor for Thin Ice.

Scientists can tell human stories about climate change, and a group of us have been working on just that for the last few years. We’ve produced a film — Thin Ice – the inside story of climate change — which follows a scientist, geologist and camera buff Simon Lamb, who is concerned at the flak his climate science colleagues have been taking.

Simon travels from the Antarctic to the Arctic. He listens to scientists talk about their work, hopes and fears, and discovers how the astonishing range of research really does fit together. By the end there are just two messages – that our ultimate goal should be zero carbon emissions (in line with the latest IPCC report), and that science really does work. As paleoclimatologist Dave Harwood says to young people at the end of the film:

Don’t be scared by this thing. Come and join in our effort. Be the best scientists and engineers you can, and we’ll deal with it.

Antarctica’s melting, seas will rise: here’s why

How is Antarctica melting? Much faster than we hoped, according to the latest research — neatly explained in the latest Peter Sinclair This Is Not Cool video for Yale Climate Connections (formerly the Yale Forum), cunningly titled Meltwater Pulse 2b. Just how fast the West Antarctic Ice Sheet will melt, and how much East Antarctica will contribute to near term sea level rise is open an open question, but the news is not good, as the latest research on the stability of the Antarctic ice sheet at the end of the last ice age suggests.

TDB today: Goodbye coastline – we are beyond the point of no return

In which I pull together the strands of the recent bad news from Antarctica and Greenland, and lament the loss of the coastline we all grew up with — no longer a theoretical possibility but a long term certainty. Check out Goodbye coastline – we are beyond the point of no return, this week’s post at The Daily Blog, and start planning for all our watery futures.

Whale meat again – Slater’s climate pseudoskeptic siren songs

New Zealand’s highest traffic blog is Cameron Slater’s Whale Oil Beef Hooked (try saying it in an Irish accent) — an aggressive right-wing sensationalist blog not noted for its delicate approach to current affairs. Unsurprisingly, Slater is an outspoken climate pseudoskeptic, with a long history of posts rubbishing climate science and the reality of climate change. This morning’s effort — The Cognitive Dissonance Of The Media On Climate Change — is pretty much par for Slater’s course, but riffs on an interesting new paper about the potential for serious additional ice loss from Antarctica which has been getting quite a bit of local media coverage (Stuff, RNZ News).

Slater’s complaint is straightforward enough: he relies on Monckton’s latest temperature trend cherry pick at µWatts and Climate Depot to demonstrate that there’s “no global warming for the last 17 years and 9 months”, shows a graph of the current increase in Antarctic sea ice, and then complains that because the NZ media has given prominence to a new study by Matthias Mengel and Anders Levermann at the Potsdam Institute ((M. Mengel, A. Levermann. Ice plug prevents irreversible discharge from East Antarctica. Nature Climate Change, 2014; DOI: 10.1038/NCLIMATE2226)) that finds that a large chunk of the East Antarctic ice sheet could be vulnerable if warming continues, then the media must be biased. As he puts it:

These scaremongering scenarios really do show the cognitive dissonance of the mainstream media and their inability to look dispassionately at the evidence before us, instead they push political lines. All of their stories have “could”, “should”, “might” and “maybe” qualifiers.

Unfortunately, Slater’s the one with the cognitive dissonance. His “dispassionate” look at the evidence is anything but, and his aggressive rejection of the new ice sheet evidence — “This report doesn’t sound plausible at all, it sounds like horse crap to me” — appears to be based entirely on his own lack of understanding of ice sheet dynamics.

TV3’s The Nation: Antarctica and public understanding of climate change

antarcticaA few days have passed since Lisa Owen’s interview with Antarctic scientists Chuck Kennicutt of the US and Gary Wilson of New Zealand on TV3’s The Nation but I hope it’s still worth drawing attention to. Programmes like The Nation tend to focus on immediate political excitements. It was therefore a pleasant surprise to see an interviewer who was reasonably well informed of the issues surrounding the effect of global warming on the Antarctic and who allowed the two scientists space to explain the far-reaching planetary consequences of Antarctic melting.

I won’t traverse the content of the interview here. It was familiar enough material to anyone who follows the science. The scientists were restrained and objective, almost to a fault. But their observations were stark enough. Gary Wilson observed that looking back in geological time we know that the last time carbon dioxide levels were at 400 parts per million the end solution of a prolonged period in that state was that the West Antarctic ice sheet retreated.

Beyond expressing pleasure at the quality of the interview and the fact that it was undertaken my main purpose in this post is to draw attention to the contribution of one of the panellists who subsequently discussed the interview (3 minutes in).
