tomo,
Isn’t history littered with examples of the majority scientific view of the day proving to be wrong? So you can hardly say it‘s settled merely because of a majority view and the evidence for and against needs continual examination.
I agree that whether it’s right or not is not a choice. Rather like people turning to religion as they near popping off it’s probably safer to assume it’s right (man influenced climate change) just in case it is, so we might as well do things that lessen our influence.
Given the exponential growth in human activity and the human population it seems unlikely that we have not affected the natural balance of the planet or that we won’t continue to do so. As well as seeking to reduce our influence (possibly a futile occupation) we should also bend our minds to preparing for the change (even if just in case).
Fair enough. I did say it was settled at any given point along a continuum. So science has the settled answer at any given point. At a later point, there could well be a different answer, based on increased study, better scientific technique, further analysis etc. That's the nature of scientific enquiry. The fact that scientific answers are continually revised over years and centuries is actually proof of the discipline's strength, not weakness.
It remains the case that new scientific solutions are found by scientists, not politicians or commentators or journalists or crusty activists.
Yes, reducing our impact on the environment does not seem crazy. And similarly it shouldn't seem crazy that if there's a possibility we might be on the brink of extinction, we should take a step back and look around before we run forward blindly.
