I’m afraid I need to agree with Krugman’s conclusion:
While Donald Trump is a prime example of the depravity of climate denial, this is an issue on which his whole party went over to the dark side years ago. Republicans don’t just have bad ideas; at this point, they are, necessarily, bad people.
There can be no excusing a systematic denial of reality, or of our single best means of understanding it, Science, no matter what the perceived economic consequences.
Understand, of course, I have no uncritical love for Democrats either, because they are not actual climate champions, and because they have simply assumed climate hawks, like myself, have no other choice than to support them, given the travesty that’s the Republican Party. Even Senator Elizabeth Warren supports paying people to live in high risk coastal areas and opposes properly assessing risk of re-flooding and damage.
Am I supposed to support her?
This is called denial. It’s a psychological condition.
And a providential warning …
