Weakened NZ ETS not responsible economic management

by Bryan Walker April 13, 2012

Tim Groser, the new Minister for Climate Change Issues, is adamant in his defence of the intention to further delay bringing the agricultural sector into the Emissions Trading Scheme beyond the current date of 2015 unless there are adequate abatement options open to them by then and unless other countries step up to the mark [...]

Welcome political forthrightness

by Bryan Walker December 5, 2011

I felt a twinge of envy watching a recent BBC Hardtalk interview with Chris Huhne, Britain’s Secretary of State for Energy and Climate Change. The tone of his statements was much more forthright than anything we’re likely to hear from New Zealand government ministers. It was no more than we have a right to expect [...]

Not good news

by Bryan Walker September 23, 2011

My reading this morning didn’t incline me to optimism. I don’t actually need reminding, but in case I did two items underlined that we remain very much on course for a 3 to 4 degree global temperature rise by the end of the century.  A new report published by the Joint Research Centre of the [...]

The Minister’s chart-junk part 2

Natural Gas is Not a Green Fuel

by Bryan Walker September 14, 2011

My heart sinks when I read enthusiastic acclamations of natural gas as a substitute for coal. It releases less CO2 on combustion, we’re told. It is a good bridge to the time when renewable energy is sufficiently developed to take over. And latterly, with the development of fracking, that’s going to be a very long [...]

Breaking the deadlock on shipping emissions

by Bryan Walker September 11, 2011

International shipping is responsible for an estimated 3 percent of global greenhouse gas emissions, equivalent to those of Germany, thirteen times those of New Zealand. On current trends they are expected to increase by 150-250 percent by 2050. They are as yet unregulated, trapped for over a decade in a familiar impasse where developed countries [...]

Anthropogenic CO2 Far Exceeds Volcanic

by Bryan Walker August 7, 2011

I was a little startled a few weeks back to see in a Waikato Times column written by former National Party MP Michael Cox the extraordinary claim that the 1991 Mt Pinatubo eruption “shot out more greenhouse gases into the atmosphere than the entire human race had emitted in its entire years on Earth”.  I [...]

Grim news on emissions

by Bryan Walker May 30, 2011

The Guardian, with the exception of the foolishness of its analysis of the climategate emails, is one of the world media’s bright spots when it comes to recognising and communicating the realities of climate change. It carried grim news yesterday. Environment correspondent Fiona Harvey reported International Energy Agency (IEA) unpublished estimates that greenhouse gas emissions [...]
