But the Trump administration and its allies in Congress will, of course, ignore this analysis. Denying climate change, no matter what the evidence, has become a core Republican principle. And it’s worth trying to understand both how that happened and the sheer depravity involved in being a denialist at this point.
Wait, isn’t depravity too strong a term? Aren’t people allowed to disagree with conventional wisdom, even if that wisdom is supported by overwhelming scientific consensus?
Yes, they are — as long as their arguments are made in good faith. But there are almost no good-faith climate-change deniers. And denying science for profit, political advantage or ego satisfaction is not O.K.; when failure to act on the science may have terrible consequences, denial is, as I said, depraved.
But climate denial has sunk deeper political roots than cancer denial ever did. In practice, you can’t be a modern Republican in good standing unless you deny the reality of global warming, assert that it has natural causes or insist that nothing can be done about it without destroying the economy. You also have to either accept or acquiesce in wild claims that the overwhelming evidence for climate change is a hoax, that it has been fabricated by a vast global conspiracy of scientists.
Why would anyone go along with such things? Money is still the main answer: Almost all prominent climate deniers are on the fossil-fuel take. However, ideology is also a factor: If you take environmental issues seriously, you are led to the need for government regulation of some kind, so rigid free-market ideologues don’t want to believe that environmental concerns are real (although apparently forcing consumers to
subsidize coal is fine).
And let’s be clear: 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.
