Climate change denier and Auckland University geographer Chris de Freitas seems to have fast access to the dialogue pages of the NZ Herald. His latest effort this week is a long ramble ostensibly around the possibility of an El Niño this year, but at its centre contains a nasty slur on the honesty of climate scientists. He confuses, presumably deliberately, predictions of a weather event in the short term with the longer term predictions of climate change.
The short term prediction relates to the possibility of an El Niño event this year. He claims NIWA’s reported 50% chance of an El Niño is not a prediction at all, but more akin to tossing a coin. This observation doesn’t stand up. NIWA doesn’t say every year that there’s a 50% chance of an El Niño. They were drawing attention to current developments which point in the direction of an El Niño.
Nevertheless de Freitas presumably sees his observation as a useful build-up to his planned attack. His next step is to comment on how incredibly complex climate systems are, and to quote no less an authority than Albert Einstein who said of the weather that prediction for even a few days ahead is impossible. Incidentally I’ve never seen a climate scientist claiming to predict the weather next week. But in de Freitas’ mind this leads to a climax:
The problem is complicated by the fact that the public usually fear the worst, and fear sells. So, if the period for which the prediction is made is beyond the end of the climate scientist’s lifetime, such as with long-term predictions of human-caused climate change, or “global warming”, any scary prediction will attract attention and hopefully also research funds or job promotion.
