Some logical analysis of the evidence, from the redoubtable Nick Hubble (for whom I have the greatest respect) of Fortune and Freedom.
It's not just the green/not green argument - it's how we do it, and the truly silly thing is that nobody seems to have come up with a feasible plan.
Sadly, being silly has never been a bar to political promotion (some might even think that being both gullible and plausible is a primary qualification for an ambitious politician), so we can't just say that we won't believe it because it's too preposterous.
We choose what we believe for better or for worse, and what we think and what we believe influences others, so it behoves each of us individually to choose very carefully when the stakes are as high as this. Going with the flow is no safeguard against the idiocy of our politicians.
