Twenty years ago I’d have crossed the street to avoid meeting John Selwyn Gummer, then agriculture minister in Margaret Thatcher’s government, chiefly famous for having attempted to feed his young daughter a beefburger at the 1990 Ipswich Boat Show to demonstrate his understanding of the risks of contracting bovine spongiform encephalopathy (aka mad cow disease) from contaminated meat. It has since killed 166 people in Britain, Cordelia Gummer not among them. I now find myself in the strange position of agreeing rather wholeheartedly with Baron Deben, as he is currently styled, in an article headlined Climate change doubters are endangering our common future published in The Australian (!) last week. And his musings on the politics of climate action provide a useful counterpoint to the astonishing submission on the NZ government’s intention to gazette a “50 by 50” target for carbon emissions made earlier this month by an Australian organisation calling itself The Carbon Sense Coalition.
