For GOP on Climate Change, a Point of No Return
Paul Krugman, NYT
MAY 15, 2014
Recently two research teams, working independently and using different methods, reached an alarming conclusion: The West Antarctic ice sheet is doomed. The sheet’s slide into the ocean, and the resulting sharp rise in sea levels, will probably happen slowly. But it’s irreversible. 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 — weighed in on climate change. Some readers may recall that in 2012 Mr. Rubio, asked how old he believed the earth to be, replied “I’m not a scientist, man.” This time, however, he 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 the power of doctrines — how support for a false dogma can become politically mandatory, and how overwhelming contrary evidence only makes such dogmas stronger and more extreme. For the most part, I’ve been focusing on economic issues, but the same story applies with even greater force to climate.
