Many of the precautionary actions that we need to take would be sensible in any event. It is sensible to improve energy efficiency and use energy prudently; it's sensible to develop alternative and sustainable and sensible ... it's sensible to improve energy efficiency and to develop alternative and sustainable sources of supply; it's sensible to replant the forests which we consume; it's sensible to re-examine industrial processes; it's sensible to tackle the problem of waste. I understand that the latest vogue is to call them ‘no regrets’ policies. Certainly we should have none in putting them into effect.
The thing that has always confused me about the climate change 'debate' is that I don't really see why there needs to be a debate in the first place. Ultimately, the best methods being proposed to combat climate change seem to come down to reducing pollution, and reducing waste. Irrespective of whether anthropogenic climate change is happening or not, these are good things in themselves. It strikes me as being a bit like the idea that bathing regularly reduces the likelihood that you will get sick. Maybe there's a chance that you won't become ill even if you don't wash yourself for a fortnight - but you would still feel better if you had, nonetheless.
