The Age Of Resilience starts tonight

AgeofResilience_logoA quick heads up that the Royal Society of New Zealand’s panel discussion series on the theme of The Age Of Resilience starts tonight at the Auckland Museum at 6pm. French and NZ experts will consider the “economic conundrum” of transitioning to a low-carbon economy and at the same time deliver a “high and sustainable level of human well-being”. On the panel are Pierre Ducret (see the NZ Herald today), Dr Suzi Kerr, Professor Catherine Larrère and Fraser Whinerary. Kim Hill will be in the chair, and the evening is being recorded by Radio New Zealand for broadcast next month. More details at the RSNZ web site, and you can download a flyer here.

Two further sessions are being held in Wellington and Christchurch: in Wellington tomorrow night on Climate in-justice? and Christchurch next Tuesday on The Anthropocene Challenge. Details and flyers from the RSNZ here. An interesting series — and if you can’t make the live recordings, all three will be on Radio NZ National in September and October as part of the Talking Heads strand.

Latest NZ ETS report: policy failure is main feature

This is a guest post by Professor Euan Mason of the School of Forestry at the University of Canterbury. It is cross-posted from his Photosynthesis blog.

New Zealand’s climate change policy failure is the main feature of the 2014 report on New Zealand’s emissions trading scheme (ETS). More than 95% of surrendered credits were imports, and the cost to emitters was approximately 10 cents per imported ‘hot air’ credit during most of 2014, compared to an average of approximately $4 for New Zealand Units (NZUs), our domestic carbon credits, during that year. In addition, during 2014 taxpayers gave 4.4 million NZUs to ‘trade exposed’ industries, representing a windfall for them of approximately $17 million, which is their allocation multiplied by the difference in price between domestic and imported credits; we essentially paid them to pollute. Given the low cost of imported ‘hot air’ carbon credits and the fact that we paid people to pollute, it is unsurprising that New Zealand now lags behind almost all of the rest of the world in its climate change response.

Since imported credits were outlawed earlier this year our NZU price has gradually risen to around $7/credit. This price is much too low to encourage the level of tree planting we need in order to avoid a blowout in our carbon accounts during the 2020s as trees planted during the 1990s are harvested. Figure 3 of the ‘Facts and Figures’ report shows that only 42% of post-1989 forests are registered in the ETS. Figure 4 shows the dramatic reduction in new forest planting and the resumption of deforestation that coincided with imports of cheap ‘hot air’ credits that began in earnest towards the end of 2011.

Antarctic sea ice: The end of the trend?

west antarctic sea iceUnusual things are happening to Antarctic sea ice extent. We are about a month away from the traditional time of maximum extent (around 20 September), and each year for the last six years, total sea ice extent around the Antarctic has been above normal. The last three years have been record-breaking, with 2014 seeing the 20 million square kilometre threshold exceeded for the first time since satellite records began in 1979 (Figure 1). But this year, sea ice growth stalled in early August and is currently going nowhere. For the first winter since 2008, total Antarctic sea ice extent is below normal (Figure 2).

What’s more, the pattern of sea ice change this winter is the opposite of the trend pattern we’ve seen over the past few decades towards more ice around the Ross Sea and less ice near the Antarctic Peninsula ((Turner, J., J. C. Comiso, G. J. Marshall, T. A. Lachlan-Cope, T. Bracegirdle, T. Maksym, M. P. Meredith, Z. Wang, and A. Orr, 2009: Non-annular atmospheric circulation change induced by stratospheric ozone depletion and its role in the recent increase of Antarctic sea ice extent. Geophys. Res. Lett., 36, L08502, doi:08510.01029/02009GL037524.)). This year, near the Antarctic Peninsula, we have more ice than normal, and less than normal north of the Ross Sea and across parts of the Indian Ocean (Figure 3). A real turn-around.

Coal, climate change, and the New Zealand economy: winners, losers, and long-term users

Cross-posted from Coal Action Network Aotearoa

As the country reeled with the news last week that Solid Energy had gone into administration with a $300m debt, another event was happening in the Pacific that puts the debate in a context that it too seldom receives in New Zealand.

On Thursday, Kiribati Prime Minister Anote Tong wrote to world leaders calling for a moratorium on new coalmines.

“Kiribati, as a nation faced with a very uncertain future, is calling for a global moratorium on new coal mines. lt would be one positive step towards our collective global action against climate change and it is my sincere hope that you and your people would add your positive support in this endeavour,” he wrote.

“The construction of each new coal mine undermines the spirit and intent of any agreement we may reach, particularly in the upcoming COP 21 in Paris, whilst stopping new coal mine constructions NOW will make any agreement reached in Paris truly historical.”

UK Economist Sir Nicholas Stern agreed: “The use of coal is simply bad economics, unless one refuses to count as a cost the damages and deaths now and in the future from air pollution and climate change,” he told Reuters (Stern’s full statement here).

In June, Pope Francis said in his encyclical that the use of “highly polluting fossil fuels needs to be progressively replaced without delay.”

What’s Beef? (The Rap Guide To Climate Chaos)

A little something for the weekend courtesy of Baba Brinkman — the Canadian “rap artist, writer, actor, and tree planter” — from his Edinburgh Festival show The Rap Guide To Climate Chaos. Familiar themes, I think you’ll find, over a blistering beat (as the young folks may say). See also Brinkman’s Rap Guide to Evolution, and in particular the marvellous Darwin Day.
