Paul Krugman: Interests, Ideology And Climate

The "real obstacle" to action on climate change:

Interests, Ideology And Climate, by Paul Krugman, Commentary, NY Times: There are three things we know about man-made global warming. First, the consequences will be terrible if we don’t take quick action to limit carbon emissions. Second, in pure economic terms the required action shouldn’t be hard to take: emission controls, done right, would probably slow economic growth, but not by much. Third, the politics of action are nonetheless very difficult.

But why is it so hard to act? Is it the power of vested interests?

I’ve been looking into that issue and have come to the somewhat surprising conclusion that it’s not mainly about the vested interests. ... What makes rational action on climate so hard is something else — a toxic mix of ideology and anti-intellectualism.

Before I get to that, however, an aside on the economics.

I’ve noted in earlier columns that every even halfway serious study of the economic impact of carbon reductions ... finds at most modest costs. ...

But wouldn’t protecting the environment nonetheless impose costs on some sectors and regions? Yes, it would — but not as much as you think. ... So why is the opposition to climate policy so intense?

Well, think about global warming from the point of view of someone who grew up taking Ayn Rand seriously, believing that the untrammeled pursuit of self-interest is always good and that government is always the problem, never the solution. Along come some scientists declaring that unrestricted pursuit of self-interest will destroy the world, and that government intervention is the only answer..., this is a direct challenge to the libertarian worldview.

And the natural reaction is denial — angry denial. Read or watch any extended debate over climate policy and you’ll be struck by the venom, the sheer rage, of the denialists.

The fact that climate concerns rest on scientific consensus makes things even worse..., right-wingers never liked or trusted scientists in the first place.

So the real obstacle, as we try to confront global warming, is economic ideology reinforced by hostility to science. In some ways this makes the task easier: we do not, in fact, have to force people to accept large monetary losses. But we do have to overcome pride and willful ignorance, which is hard indeed.
