Until perhaps two years ago, whether climate change was occurring and whether it was anything to do with human activity were topics that politically-minded people debated. Greens urged that the burning of fossil fuels was going to heat up the planet, raising sea levels, expanding deserts, and causing much misery. Climate change sceptics urged that the evidence was not there, and that we should not shackle the Market, undermine trade and limit the development of poorer nations on the basis of scare stories and hype.
In my view that debate went on rather longer than was fruitful, and because some people still cling to the most sceptical positions there, the real debate that we should be having has been seriously hobbled. I shall explain.
I know lots of very smart people who still don’t believe there is any good evidence of human-induced climate change. I understand why, as intellectually-confident individuals with lots of letters after (an sometimes before) their names they feel able to defy the overwhelming consensus of a scientific community. Presumably many people that have become environmental scientists in the past twenty years took up research in that area precisely because they already believed that there was human-induced climate change, having been influenced by the concerns of green writers in the late 1980s. That their subsequent research has confirmed their initial prejudices may make figures along the lines of “99% of all climate scientists think that…” My guess is that the proportion of experts in feminist ethics who think that women had a good deal in the 1950s or that the husband is the head of the wife will be rather small, also.
But although, given the likely biases in the climate change research community, I think it appropriate to be polite to listen to my very clever friends’ scepticism, the fact remains that we forfeited our right to be listened to concerning the details of this debate when we chose not to do environmental science. So now our entertaining dinner table debates cannot hope to influence policy.
