Paul Krugman: Points of No Return

Can anything reverse the growing hostility to science within the Republican Party?:

Points of No Return, by Paul Krugman, Commentary, NY Times: Recently two research teams, working independently and using different methods, reached an alarming conclusion: The West Antarctic ice sheet is doomed. ... Even if we took drastic action to limit global warming right now, this particular process of environmental change has reached a point of no return.
Meanwhile, Senator Marco Rubio of Florida — much of whose state is now fated to sink beneath the waves —... confidently declared the overwhelming scientific consensus on climate change false, although in a later interview he was unable to cite any sources for his skepticism.
So why would the senator make such a statement? The answer is that like that ice sheet, his party’s intellectual evolution (or maybe more accurately, its devolution) has reached a point of no return, in which allegiance to false doctrines has become a crucial badge of identity.
I’ve been thinking a lot lately about ... how support for a false dogma can become politically mandatory, and how overwhelming contrary evidence only makes such dogmas stronger and more extreme. ... To see how it works, consider a topic I know well: the recent history of inflation scares. ...
Inflation phobia has always been closely bound up with right-wing politics; to admit that this phobia was misguided would have meant conceding that one whole side of the political divide was fundamentally off base about how the economy works. So most of the inflationistas have responded to the failure of their prediction by becoming more, not less, extreme in their dogma...
The same kind of thing is clearly happening on the issue of global warming. ... As the evidence for a changing climate keeps accumulating, the Republican Party’s commitment to denial just gets stronger. ...
And truly crazy positions are becoming the norm. A decade ago, only the G.O.P.’s extremist fringe asserted that global warming was a hoax concocted by a vast global conspiracy of scientists (although even then that fringe included some powerful politicians). Today, such conspiracy theorizing is mainstream within the party, and rapidly becoming mandatory; witch hunts against scientists reporting evidence of warming have become standard operating procedure, and skepticism about climate science is turning into hostility toward science in general.
It’s hard to see what could reverse this growing hostility to inconvenient science. As I said, the process of intellectual devolution seems to have reached a point of no return. And that scares me more than the news about that ice sheet.
