by Gareth May 1, 2013

Any day now the Mauna Loa carbon dioxide measurement station is going to bump through 400 part per million, and stay there for a week or two. In my Daily Blog column this week I ruminate on what that means by taking a look at the last time CO2 stayed over 400 ppm for an [...]

Brother, can you spare $3.10 for a tonne of carbon dioxide?

In which Mr February (aka Simon Johnson) looks at the uselessness of the report of the Finance and Expenditure Committee on the Climate Change Response (Emissions Trading and Other Matters) Amendment Bill, people begging on Lambton Quay in Wellington, and the fact that the spot price for a tonne of carbon dioxide is the same [...]

Moon-walking with due legal process to a very hot place – Neil Armstrong, coal mining & global warming

by Mr February August 30, 2012

On the same day as the death of Neil Armstrong, the first astronaut to step onto the Moon, became public, the NZ High Court moonwalked its way to an off-the-world moment.

by Gareth November 3, 2011
