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 Climate Show #8: Kevin Trenberth and our shaky future

by Gareth March 3, 2011

The Climate Show returns with a packed show, featuring one of the world’s best known climate scientists, NZ-born, Colorado-based Dr Kevin Trenberth — star of the Climategate “where’s the missing heat” emails. He’s been in New Zealand to visit family (experiencing the Christchurch quake in the process) and to attend a conference, and his comments [...]

Fixing the Sky

by Bryan Walker October 8, 2010

The notion that if it comes to the worst in climate change we can fall back on geoengineering  receives little credence in James Rodger Fleming’s new book Fixing the Sky: The Checkered History of Weather and Climate control.

Challenged by Carbon

by Bryan Walker August 20, 2010

Oil industry geologists have hardly been noted for their readiness to accept the findings of climate science. The American Association of Petroleum Geologists, a large international organisation of 31,000 members, is non-committal in its 2007 statement, though that was admittedly an advance on their previous rejection of anthropogenic warming.  Bryan Lovell has worked as a [...]

Rudd brooks no denial

by Bryan Walker November 19, 2009

Somehow Kevin Rudd’s climate change speech to the Lowry Institute earlier this month escaped my detection systems and it took Joseph Romm’s Climate Progress post today to draw it to my attention. New Zealanders, whose political leaders avoid big statements on the issue, can welcome its unequivocal tone. There seems an air of unreality to [...]

His substantial new book Our Choice: A Plan to Solve the Climate Crisis has grown out of the more than 30 lengthy and intensive “Solution Summits” he has organised to enable leading experts from round the world to share their knowledge and experience [...]

Blackleg miner

by Gareth May 9, 2009

Solid Energy, NZ’s state-owned coal mining company, is promoting an alternative to an economy wide emissions trading scheme. According to Carbon News, the approach is being “heavily peddled to policy makers and others in Wellington”, and it is seen to have “great simplistic appeal”. Carbon News has made the document, A Durable Climate Change Strategy [...]

Catch a (micro)wave

by Gareth October 1, 2008

There are some amazing people in NZ. Just when I’m tearing (what’s left of) my hair out at the idiocy of some politicians, along comes a news story to gladden the heart of anyone living in the real world. Yesterday, Blenheim-based start-up Carbonscape reported that it has just begun batch production of charcoal in a [...]
