Matt Ridley: The Climate Wars And The Damage To Science
Global Warming Policy Foundation, 5 November 2015
At the heart of the debate about climate change is a simple scientific question: can a doubling of the concentration of a normally harmless, indeed moderately beneficial, gas, from 0.03% of the atmosphere to 0.06% of the atmosphere over the course of a century change the global climate sufficiently to require drastic and painful political action today? In the end, that’s what this is all about. Most scientists close enough to the topic say: possibly. Some say: definitely. Some say: highly unlikely. The ‘consensus’ answer is that the warming could be anything from mildly beneficial to dangerously harmful: that’s what the IPCC means when it quotes a range of plausible outcomes from 1.5 to 4 degrees of warming.
On the basis of this unsettled scientific question, politicians and most of the pressure groups that surround them are furiously insistent that any answer to the question other than ‘definitely’ is vile heresy motivated by self-interest, and is so disgraceful as to require stamping out, prosecution as a crime against humanity, investigation under laws designed to catch racketeering by organized crime syndicates, or possibly the suspension of democracy. For yes, that is what has been repeatedly proposed by respected and senior figures in the climate debate.
