New Zealand’s changing climate and oceans: new Gluckman report out today

The Prime Minister’s science advisor, Sir Peter Gluckman, today released a new report looking at the probable impacts of climate change in New Zealand over the next 40 years. The report, New Zealand’s Changing Climate and Oceans: The impact of human activity
and implications for the future
(pdf) is:

… intended to update the public on current scientific understandings of climate change and ocean acidification. In particular, it focuses on how these changes are likely to affect New Zealand’s climate and industries at a regional level over coming years.

The timing of the report — which appears at first glance to offer a reasonable overview of our current understanding of likely local climate changes — seems a trifle odd. In a matter of months the IPCC will release the first part of its Fifth Report, covering the underlying science, and while we’ll have to wait until March next year for the Working Group 2 report on regional impacts, Gluckman and his team would have had a firmer foundation for their report with only a modest delay.

I’ll be reading the report carefully over the next few days, and will have more to say in due course. I’m particularly interested in exploring how Gluckman approaches the risks associated with local climate changes, and his take on how the wider international context will impact New Zealand.

NZ Climate Change Conference 2013 day one

It’s been a long day in Palmerston North at the NZ Climate Change Conference for 2013. There’ll be nothing particularly cogent in this post, but I have recorded interviews with two of the VUW 3 — Jim Renwick tells me about the southern annular mode,the ozone hole and sea ice, and Dave Frame gives me his take on TCS, ECS and Oxford — plus Professor Barry Smit from the University of Guelph in Canada talks about Inuit, wine and uncertainty. I’ll be posting those interviews later this week, along with some more I hope to grab tomorrow, and I’m lining up some guest posts for the future. All fascinating stuff — and I have to say it’s a great relief to find a bunch of really smart people who are focussed on the nuts and bolts of the issue, not the sceptic sideshow.

TDB today: The Big Crunch

My column at The Daily Blog this week looks at last week’s call from the Millennium Alliance for Humanity & the Biosphere (a cross-disciplinary group of hundreds of top scientists) for urgent action to address climate change, extinctions, loss of ecosystem diversity, pollution, and human population growth and resource consumption. To call it a big challenge would be an understatement… Comments over there please.

Thin Ice: the inside story of climate science

Now showing at an Antarctic base near you (and quite a few places elsewhere), a documentary about climate science, filmed and put together by VUW geophysics professor Simon Lamb. The idea for Thin Ice – the inside story of climate science was born over a cup of tea in Wellington in 2006, when Peter Barrett of VUW suggested that Lamb, then at Oxford, make the film. Lamb went on to visit many parts of the world, and talk to a who’s who of climate scientists. Should be well worth a couple of hours of anyone’s time — especially those prone to accusing climate scientists of fraud.

Thin Ice is a joint effort between VUW, Oxford University and DOX Productions, and there are screenings in Auckland, Christchurch, Dunedin and Wellington today and tomorrow, as well as in Australia, Canada, the UK and USA and many other places. You can also download or stream the film to your PC or tablet. I’ll be watching on my iPad this evening. Reviews etc welcome in comments to this post…

A Short Introduction to Climate Change

Tony Eggleton’s A Short Introduction to Climate Change is an excellent account of climate science for the general reader. The author is a retired geology professor from the Australian National University. Two widely read climate change deniers, Ian Plimer and Bob Carter, are also retired Australian geology professors, but Eggleton is not of their ilk. He comes at the subject from a concern about climate change and a wish to explain to readers who are uncertain about the topic why there is reason for concern.

The book is grounded in the careful science which has contributed to our understanding of the danger in which we now stand. Eggleton has not worked in the field of climate, but recognises the authenticity of the findings of climatologists. His opening chapter, The Spirit of Enquiry, offers a clear account of the process by which science across all its fields advances. He highlights the fact that most climate science is done by groups, all of whom need to be confident of the reliability of their colleagues. He explains the rigorous process of peer reviewed papers and the comprehensive scrutiny from fellow scientists which follows their publication. He ponders the fact that some hypotheses are of the type that involves a choice between only two possibilities. If one is not true the other must be so. How will the theory of climate change caused by the burning of fossil fuels be viewed in 100 years from now? “Interpretations evolve, change and sometimes settle into accepted fact: the Sun is at the centre of the solar system, the continents have drifted and smoking does damage the lungs.”
