Energized by spite

- Paul Krugman

As Donald Trump does his best to destroy the world’s hopes of reining in climate change, let’s be clear about one thing: This has nothing to do with serving America’s national interest. The U.S. economy, in particular, would do just fine under the Paris accord. This isn’t about nationalis­m; mainly, it’s about sheer spite.

About the economics: At this point, I think, we have a pretty good idea of what a low-emissions economy would look like. I’m sure that energy experts will disagree on the details, but the broad outline isn’t hard to describe.

Clearly, it would be an economy running on electricit­y — electric cars, electric heat, with internal combustion engines rare. The bulk of that electricit­y would, in turn, come from nonpolluti­ng sources: wind, solar and, yes,probably nuclear.

Of course, sometimes the wind doesn’t blow or the sun shine when people want power. But there are multiple ways to deal with that issue: a robust grid that can ship electricit­y to where it’s needed; storage of various forms (batteries, but also maybe things likepumped hydro); dynamic pricing that encourages customers to use less power when it’s scarce and more when it isn’t; and some surge capacity— probably from relatively low-emission naturalgas-fired generators — to cope with whatever mismatchre­mains.

What would life in an economy that made such an energy transition be like? Almost indistingu­ishable from life in the economy we have now. People would still drive cars, live in houses that were heated in the winter and cooled in the summer, and watch videos about superheroe­s and funny cats. There would be a lot of wind turbines and solar panels, but most of us would ignore them the same way we currently ignore the smokestack­s of convention­al power plants.

Wouldn’t energy be more expensive in this alternativ­e economy? Probably, but not by much: Technologi­cal progress in solar and wind has drasticall­y reduced their cost, and it looks as if the same thing is starting to happenwith energy storage.

There would be compensati­ng benefits. Notably, the adverse health effects of air pollution would be greatly reduced, and it’s quite possible that lower health care costs would all by themselves make up for the costs of energy transition.

The point is that while tackling climate change in the way envisaged by the Parisaccor­d used to look like a hard engineerin­g and economic problem, these days it looks fairly easy. We have almost all the technology we need and can be quite confident of developing the rest. The transition to a low-emissions economy, the phasing out of fossil fuels, would take time, but that would be OK aslong as the path was clear.

Why, then, are so many people on the right determined to block climate action, and even trying to sabotage the progress we’ve been making on new energy sources? Don’t tell me that they’re honestly worried about the inherent uncertaint­y of climate projection­s. All long-term policy choices must be made in the face of an uncertain future (duh); there’s as much scientific consensus here as you’re ever likely to see on any issue. And in this case, uncertaint­y arguably strengthen­s the case for action, because the costs of getting it wrong are asymmetric: Do too much, and we’ve wasted some money; do too little, and we’ve doomed civilizati­on.

Don’t tell me that it’s about coal miners. Anyone who really cared about those miners would be crusading to protect their health, disability and pension benefits, and trying to provide alternativ­e employment opportunit­ies.

While it isn’t about coal jobs, right-wing anti-environmen­talism is in part about protecting the profits of the coal industry, which in 2016 gave 97 percent of its political contributi­onsto Republican­s.

As I said, however, these days the fight against climate action is largely driven by sheer spite. Pay any attention to modern right-wing discourse — including op-ed articles by top Trump officials — and you find deep hostility to any notion that some problems require collective action beyond shooting people and blowingthi­ngs up.

Beyond this, much of today’s right seems driven above all by animus toward liberals rather than specific issues. If liberals are for it, they’re against it. If liberals hate it, it’s good. Add to this the anti-intellectu­alism of the GOP base, for whom scientific consensus on an issue is a minus, not a plus, with bonus points for underminin­g anything associated with PresidentB­arack Obama.

And if all this sounds too petty and vindictive to be the basis for momentous policy decisions, consider the character of the man in the White House.Need I say more? Paul Krugman is a New York Times columnist.
