Trump’s Paris pullout endangers the planet

-

Decades from now — if sea levels continue rising, polar ice caps keep melting and weather patterns grow ever more extreme — people might well look back at the spring of 2017 as a key turning point in the failed effort to stave off catastroph­ic, human-induced climate change.

President Trump’s decision Thursday to withdraw the United States, the world’s second largest emitter of heat-trapping carbon dioxide, from the Paris climate agreement deals a body blow to one of the best hopes for slowing a ruinous rise in global temperatur­es.

By breaking ranks with nearly 200 nations, the United States joins only Syria (which is riven by civil war) and Nicaragua (which thinks the Paris agreement isn’t ambitious enough) as the odd countries out. The Trump administra­tion’s action abdicates America’s moral leadership and makes it easier for other nations to renege on their own pledges to curb greenhouse-gas emissions.

In making his reckless decision, Trump defied the advice of the world’s leading climate scientists. Of Pope Francis and other religious leaders. Of the leaders of the seven wealthiest democracie­s. Of major corporatio­ns, including Chevron, Google, Facebook and Apple. Of members of his own inner circle, including son-in-law Jared Kushner and daughter Ivanka. Of his own secretary of State, a former ExxonMobil CEO.

And Trump ignored the wishes of most Americans, seven out of 10 of whom favor the Paris agreement.

But the president — prodded by chief strategist Steve Bannon, Environmen­tal Protection Agency administra­tor Scott Pruitt and coal-state Republican­s in Congress — thinks he knows better. At Thursday’s Rose Garden announceme­nt, Trump argued that the 2015 agreement “handicaps the United States economy,” even though there is no binding deal, only voluntary pledges by each nation to reduce greenhouse gas emissions.

He expressed concern about job-killing restrictio­ns. Yet the Paris accord restricts nothing. Instead, it relies on peer pressure and transparen­cy to limit global warming to a more tolerable level. Trump could have revised President Obama’s pledges without ending U.S. participat­ion.

Trump made a nod toward renegotiat­ing the Paris agreement, or crafting an entirely new pact that would be “fair” to the United States. But it’s hard to imagine other nations rushing back to the bargaining table after Trump walked away from an agreement that grew out of decades of arduous climate talks.

Other government­s, notably in the European Union and China, vow to forge ahead developing the clean-energy technologi­es that will be the drivers of economic growth in the 21st century. But global warming is a problem that requires a global solution. The margin for tilting the planet away from catastroph­ic climate change in the future is slim, and no matter the slack picked up by other nations in the absence of U.S. leadership, it might not be enough.

The 45th president dreams of a legacy where America is great again. There was no greatness in the decision he rendered Thursday, just the heightened prospect of a climate-stricken globe left behind for future generation­s.
