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.Here is what Rubio said:
Meanwhile, Senator Marco Rubio of Florida — much of whose state is now fated to sink beneath the waves — weighed in on climate change.
I do not believe that human activity is causing these dramatic changes to our climate the way these scientists are portraying it," he said. "And I do not believe that the laws that they propose we pass will do anything about it. Except it will destroy our economy.So where is the contradiction? Both Rubio and the scientists seem to agree that no proposed laws will do anything about the West Antarctic ice sheet.
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. ...Krugman is famous for errors. Here is what he wrote in 1998, several years after Amazon, Yahoo, and Ebay made it big:
Why the bad behavior? Nobody likes admitting to mistakes, and all of us — even those of us who try not to — sometimes engage in motivated reasoning, selectively citing facts to support our preconceptions.
But hard as it is to admit one’s own errors, it’s much harder to admit that your entire political movement got it badly wrong.
By 2005 or so, it will become clear that the Internet's impact on the economy has been no greater than the fax machine's.
