How Should the Fed Deal With Climate Change?

The climate crisis is at high risk of becoming an economic crisis.

That is an increasingly widespread view among leading economic thinkers — that a range of economic and financial problems could result from a warming planet and humanity’s efforts to deal with it. But if you believe that to be true, what should the United States’ economist-in-chief do about it?

That question has taken new urgency as President Biden weighs whether to reappoint Jerome Powell to another term leading the Federal Reserve or choose someone else.

Climate activists and others on the left have argued that Mr. Powell should be replaced by someone with stronger credentials as a climate hawk. Demonstrators backing this cause were planning to protest at an annual Fed symposium in Jackson Hole, Wyo., starting Thursday, but the event was made online-only at the last minute because of a rise in coronavirus cases. Among other things, they want the Fed to use its regulatory powers to throttle the flow of bank lending to carbon-producing industries.

At the same time, some Republicans are assailing the Fed for mere research efforts involving climate. It is clear there would be a huge outcry on the right if a new Fed chair were to take an activist stance in trying to limit the availability of capital inenergy-extraction businesses.

So far, Mr. Powell and other leaders at the central bank have taken a middle ground. They’ve committed to studying the ways global warming will affect the economy and the financial system, and they’re factoring those conclusions into their usual jobs of guiding the economy and regulating banks — but not trying to manage how loans and resources are allocated.

Arguably, one of the more important things the Fed can do to help fight climate change is to excel at its primary job: maintaining a stable, strong economy. Consider some surprising public opinion data.

Since 1989, Gallup has polled Americans about whether climate change worried then personally. The net share of people who have expressed concern — those who have said they worry about climate “a fair amount” or “great deal” versus those who have worried “only a little” or “not at all” — offers a sense of how seriously Americans take the threat.

The net share of people worried about climate change reached its peak not in recent years, when the damaging effects have become more visible. The peak was in April 2000, when the share of people worried about the climate was 45 percentage points higher than the share not worried. That was also one of the best months for the U.S. economy in decades, near the peak of the late 1990s boom, with unemployment a mere 3.8 percent.

Two of the times when climate worry in the survey hit a low were in 2010 and 2011, in the aftermath of the global financial crisis, when the net shares of those worried versus not worried were only four and three percentage points.

Using a broader range of evidence from both the United States and Europe, two political scientists at the University of Connecticut, Lyle Scruggs and Salil Benegal, found that a decline in climate concern in that period was driven significantly by worse economic conditions, which increased worry about more immediate issues. In times of scarcity, people tend to think less of policies with long-term payoffs.

“The state of the economy affects people’s sensitivity to the future versus the present,” Professor Scruggs said. “Historically climate change has fallen into the same camp as a lot of other environmental issues, where people’s answers tend to wax and wane with the economy.”

If a central bank can achieve consistent prosperity, this research suggests, it may change some political dynamics on aggressive climate action. Prosperity could support branches of government that have more explicit responsibility for curtailing greenhouse gases, building out clean energy capacity, or helping communities adapt to more extreme weather.

Not everyone who studies public opinion on climate agrees.

Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, attributes the decline in concern about climate change in the early 2010s not to the weak economy, but to widening political polarization and a pivot of conservative media toward climate change denialism.

“What we saw was a symbiotic relationship between conservative media, conservative elected officials and the conservative public,” he said. “That drove the shift. It wasn’t the economy.”

A paper published this summer by Michael T. Kiley, a Fed staff member, analyzed how temperature variations affect economic performance. It concluded that climate change may not change the typical rate of growth in the economy over time, but could make severe recessions more common. A major crop failure, for example, would lower G.D.P. directly and could simultaneously create economic ripple effects such as bank failures.

And Lael Brainard, a Fed governor and potential Biden appointee to become the next chair, has emphasized that the unpredictable nature of climate change could make obsolete the historical models on which economic policy is based.

“Unlike episodic or transitory shocks, climate change is an ongoing, cumulative process, which is expected to produce a series of shocks,” she said in a March speech. “Over time, these shocks can change the statistical time-series properties of economic variables, making forecasting based on historical experience more difficult and less reliable.”

If Ms. Brainard is correct, it raises a dispiriting possibility: As the planet gets hotter, it could make it harder to keep the economy on an even keel. But the worse the economy performs, the more toxic and dysfunctional climate politics may become.
