Scientists investigate how climate changes, politicians (should) decide what to do about it. Tough jobs. Artists have just as difficult a job: to comment on the reality and unreality they see in society’s responses to the climate threat, and by doing so motivate us to create a liveable future. In High Water, a new anthology […]

It is profoundly depressing to hear pundits and politicians talking about the prospects for economic growth with no reference to either equity or environmental constraints.

Sciblogs editor Peter Griffin recently gave climate denial activists Bryan Leyland and Bob Carter a “right of reply” to my post pointing out the errors and inconsistencies in a Dominion Post op-ed penned by the pair.

Reluctant policy makers use this uncertainty to support a “wait and see” response to climate change. Prominent American economists Gernot Wagner and Martin Weitzman in their recent book Climate Shock: The Economic Consequences of a Hotter Planet are scathing in […]

The Dominion Post, the newspaper of record for New Zealand’s capital city, today gave great prominence to an opinion piece by high profile climate denialists Bob Carter and Bryan Leyland titled Hypothetical global warming: scepticism needed1. It’s a “Gish Gallop” of untruths, half-truths and misrepresentations — a piece so riddled with deliberate errors and gross […]
