A science-based carbon budget for New Zealand - Guest Work

Guest Work Apr 19, 2016

By Dr George Preddey In my 17th submission to all MPs and other worthies on Budget Day, 20 May 2015 (Budget Day), I suggested alternative proposals for New Zealand’s climate change INDCs (intended nationally determined contributions).  These proposals dispensed with the pseudo-econometrics that characterised much of the discussion document and worked backwards from an essential goal of net carbon … Read More

Painting features as bugs: NZ’s carbon emissions trading scheme - The Dismal Science

Eric Crampton Apr 18, 2016

I hadn’t quite understood New Zealand’s carbon emissions trading scheme before I moved to Wellington. The thing seemed a little dodgy with a fair bit of reliance on dubious foreign credits. But then the genius of the thing was explained to me. I’ve not looked at it properly myself, but the story is interesting, and seems plausible. It goes something … Read More

Emissions trading at Paris climate talks sets us up to fail - Guest Work

Guest Work Dec 15, 2015

Steffen Böhm, University of Essex The Paris Agreement has mostly been greeted with enthusiasm though it contains at least one obvious flaw. Few seem to have noticed that the main tool mooted for keeping us within the 2℃ global warming target is a massive expansion of carbon trading, including offsetting, which allows the market exchange of credits between … Read More

Five things you need to know about the Paris climate deal - Guest Work

Guest Work Dec 13, 2015

Simon Lewis, UCL The UN climate talks in Paris have ended with an agreement between 195 countries to tackle global warming. The climate deal is at once both historic, important – and inadequate.

Climate and the rise and fall of civilisations: a lesson from the past - Guest Work

Guest Work Dec 11, 2015

Andrew Glikson, Australian National University 2015 will likely be the hottest year on record, beating the previous record set only in 2014. It is also likely to be the first year the global average temperature reaches 1℃ above pre-industrial temperatures (measured from 1880 – 1899). Global warming is raising temperatures, and this year’s El Niño … Read More

1.5 to stay alive: big issues for small countries as Paris climate talks get down to nitty gritty - Hot Topic

Cindy Baxter Dec 09, 2015

I’ve been in Paris for over a week now, and the speed at which everything goes past, including time, is frightening.   I think the 40,000 expected have now all arrived.  I’m getting worried the only Eiffel Tower I’ll see is the one made of red folding chairs at the end of the “Champs Elysee” at the meeting. We began last … Read More

How fast can we transition to a low-carbon energy system? - Guest Work

Guest Work Dec 02, 2015

Paul N Edwards, University of Michigan The world’s nations are convening in traumatized Paris to hammer out commitments to slow down global climate change. Any long-term solution will require “decarbonizing” the world energy economy – that is, shifting to power sources that use little or no fossil fuel. How fast can this happen, and what could we do to … Read More

NZ: pushing the world to go beyond 2 degrees - Hot Topic

Cindy Baxter Dec 05, 2014

New Zealand is coming under increasing scrutiny in Lima, not least because it’s our turn to be reviewed by the UNFCCC process. Early next week our representatives will have to defend our position and our lack of action to 190 governments in our first “multilateral assessment.” Already, there have been some tough questions, coming especially […] … Read More

Carbon cycling in mountain ranges – Our environmentally friendly Southern Alps - Waiology

Waiology Nov 10, 2014

By Sarah Mager The Southern Alps of New Zealand are the source of some of New Zealand’s most iconic river systems.  The development of the South Island has been intimately connected with these powerful water sources. For instance, the Clutha initially provided a critical navigation route into Central Otago and the early gold fields; the Waitaki sustains eight hydroelectrical power … Read More
