Human stupidity and the NZ election (Heigh ho! Heigh ho!)

by Gareth November 23, 2011

I’ve been writing about climate science and policy for the last five years, and taking an interest in the subject for far longer, but I’ve seldom read more depressing news than Fiona Harvey’s Guardian article last week — Rich nations ‘give up’ on new climate treaty until 2020. According to Harvey, expectations for the UN [...]

by Gareth November 9, 2011

Environment minister Nick Smith, Labour’s David Parker and the Green Party’s Kennedy Graham debate climate policy in these edited highlights from the first of Oxfam NZ’s election debates, held last week in Auckland. Debate ranged from whether New Zealand can become carbon-free to the likelihood of a cross-party agreement on long-term issues that last more [...]

A ton too far (more bad news)

by Gareth April 12, 2011

At the Climate Futures Forum in Wellington a couple of weeks ago, David Karoly discussed the idea of considering carbon emissions as a “stock” problem, not a “flow” problem. If we want to give ourselves a 75 percent chance of coming in below a 2ºC rise in the global average temperature, then we (as in [...]

Routefinding the future: reflecting on the climate futures forum

by Gareth April 5, 2011

Two busy days in Te Papa last week, and a lot to think about. The Climate Futures Forum organised by the Climate Change Research Institute at VUW was fascinating and disturbing in equal measure. Fascinating because it’s hard not to be interested when a lot of very smart people are feeding you information, and disturbing [...]

Garnaut update on climate science: avoiding high risks will require large changes

by Gareth March 10, 2011

Ross Garnaut, the Australian government’s climate change adviser, today published the science update [PDF] to his 2008 report. It warns that recent research has “confirmed and strengthened” the view that the earth is warming and humanity is to blame. Temperatures and sea level continue to rise, and there are worrying signs that a 2ºC target [...]

Zero net emissions by 2050 – preferably sooner

by Gareth March 1, 2011

I’ve just sent my submission on the NZ government’s intention to make a formal commitment to a target of a 50 percent reduction in net greenhouse gas emissions by 2050 to the Ministry of the Environment — barely squeaking in before the published deadline. My original intention was to submit a closely argued case for [...]

The road to ruin

by Bryan Walker February 27, 2011

Kevin Anderson from the Tyndall Centre for Climate Change at the University of Manchester has been sounding alarms about the inadequate rate of reduction of greenhouse gas emissions for some years now. He’s done it again in a sobering paper written with colleague Alice Bows and recently published in the Philosophical Transactions of the Royal [...]

Europe looks to bolder targets

by Bryan Walker February 22, 2011

No doubt the New Zealand climate change minister will point out that the New Zealand’s emissions profile is different from that of the EU and that the exchanges about reduction targets that have been taking place in Europe in recent days therefore have little relevance for us. Nevertheless I have taken heart from reading about [...]

An immediate halt to CO2 emissions is an absolute necessity…

by Gareth February 8, 2011

…if we are to maintain the health of ocean ecosystems, says Professor Ove Hoegh-Guldberg, Director of the Global Change Institute at the University of Queensland in this video presentation, given to a symposium at the recent Our Changing Oceans conference in Washington DC. It’s sobering viewing. Here are the primary messages from the symposium: There [...]

Copenhagen Accord puts world on pathway to 3ºC

by Gareth April 22, 2010

German scientists have added up the emissions reductions pledged in the Copenhagen Accord and calculate that they put the planet on a pathway that misses the Accord’s stated 2ºC target, and only delivers a 50/50 chance of coming in under 3ºC by the end of the century. In an opinion article in this week’s Nature, [...]
