New Zealand’s leading right wing blogger, National Party spinmeister and opinion poll guru David Farrar, this morning allowed himself the luxury of a rant about the New Zealand Herald‘s coverage of a new paper on sea level during the late Pliocene. In a post teasingly titled “Alarmist bullshit“, he manages to demonstrate his rudimentary grasp of the facts, misunderstands the real story behind the new research, and ends up shooting himself in the foot. Here’s David in full flow:
Anyone who thinks public policy today should be based on a forecast of what the climate might be in 5,000 years is nuts. Look at how the world has changed in just 100 years let alone hundreds or thousands. Hell in 1,000 years we may be living on Mars.
The Herald should be ashamed for saying that the projected increase could “dramatically transform” our coastal boundaries. A change over 1,000 years+ is not dramatic. It’s like saying the separation of Gondwana was dramatic.
20 metres is a lot of sea level rise. Here’s what 20 metres would mean for my nearest city, poor old quake-plagued Christchurch, courtesy of the Firetree sea level rise calculator. The central business district is under water, the new shoreline well to the west. At a rough guess, I’d say 80% of the city is flooded, and Banks Peninsula is an island once more.
I think that can be reasonably described as a dramatic transformation of the South Island coastline, even if it does take 1,000 years to happen. DPF might like to note that coping with two metres per century sea level rise is nobody’s picnic. But his misunderstanding runs deeper…
My inbox in the last month has filled with emails about denier articles in leading New Zealand newspapers. It’s been a veritable crank central across the country. They include the 
There’s a terrible tyranny in being a columnist for a national newspaper, required to produce entertaining and informative copy every week. It’s a hard job, having an opinion and expressing it cogently. Some writers struggle and succeed, others strive and fail dismally. The NZ Herald — the newspaper of record for NZ’s biggest city — has a couple of fine examples of the latter: old curmudgeon Garth George, who meets the difficulties inherent in his job by 
“There is a danger that, in trying to encourage major emitters to sign up to a new agreement or to bridge the Kyoto legal gap, New Zealand might commit itself to something short of a global deal that binds us to making economic sacrifices which are not reflective of fair burden sharing.” So wrote David Venables, executive director of the Greenhouse Policy Coalition, in the
