On the Q & A show a few days ago Nick Smith made some pretty wild claims about the supposed costs to New Zealanders if NZ was to comit to the '40 per cent by 2020 on 1990 levels' emissions that the scientists say is required.
Of course he didn't say anything about the potential costs of not doing enough to avert climate change but what he did say turned out to be blatently false scaremongering.
Keith Ng over at publicaddress.net provides a beautifully succinct analysis of the flaws in Nick's argument in a blog titled 'Nick Smith. Spanking. Now.' The ensuing discussion is also worth a look (and is where I got the title of this blog).
You can listen to Keith talking about this over at wammo.
