If, by insulating my house, choosing a perfectly acceptable but more economical car and reducing my mileage, using less electricity/fuel, avoid air travel, eating less meat and recycling I can help, even if it is in a microscopically small individual way, then I am pleased to do so. I also save a fair bit of money at the same time.
The evidence for climate change caused, at least in part, by human activities, is very strong. As a fallibalist I accept that we can be wrong about things. Often. However in this case it seems better we act as if we can make a difference now - so if we are right, we may well have been doing the right things to change the situation and if we are wrong, we didn't cause ourselves any individual issues - and actually saved money and became more efficient. Efficiency is good - because then we are not contributing as much to the rapid depletion of finite stocks of fossil fuels - and reduce the scale of the energy generation/distribution challenge that we are facing.
