"The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts."
That would suggest those people all have in common that doubts inhibit action, and that they just have different and not very good approaches to resolving that conflict. The best way is have action without removing the doubts.
And that is relevant for the climate change debate. Because for instance a blocker is "nothing can be done unless we agree there is human made climate change". But you don't need to be blocked by that and the engineering approach that for instance Freeman Dyson advocates(global soil management) does not rely on proof that humans are the cause or even that the climate predictions will all come true. It just offers control over whatever happens.
