As globe warms, Trump rolls back environmen­tal progress

-

Seemingly every month provides alarming new evidence of human-caused climate disruption. Last month was the hottest February on record globally, shattering the previous record, according to analyses by NASA and the National Oceanic and Atmospheri­c Administra­tion.

Nearly all climate scientists agree that the key ingredient for rising temperatur­es — on land and in the oceans — is the accumulati­on of heat-trapping greenhouse gases in the atmosphere.

That’s why the best hope of heading off catastroph­ic climate change lies in curbing greenhouse gas emissions, the whole basis for the 2015 Paris Agreement signed by 197 nations.

And it’s why the United States, as the world’s second-largest emitter of carbon dioxide, pumping 6 billion tons into the air each year, took steps under President Obama to reduce carbon pollution through the next decade by 26% from 2005 levels.

Now, less than two months into his presidency, Donald Trump is acting to reverse America’s progress on climate change.

On Wednesday, the president told an audience at a former industrial plant near Detroit that he’d roll back tough standards aimed at nearly doubling the fuel economy average for cars and trucks to 54.5 miles per gallon by 2025. Those regulation­s, devel- oped in 2012, have proved in their first phase to be a good way to jump-start efficiency.

A second phase of even tougher standards, for 2022-25 car and truck models, might be a bridge too far. Those standards could unfairly drive up vehicle costs and hamstring automakers with vehicles people won’t buy, at least not until gas prices rise again. A better alternativ­e would be a carbon tax rebated to consumers, an idea recently pushed by a slate of Republican elder statesmen.

But Trump doesn’t seem interested in alternativ­e ways for saving the planet, only in demolishin­g Obama’s climate legacy. Next on the new president’s to-do list is rewriting rules mandating cleaner-operating power plants, which, along with autos, create about 60% of U.S. greenhouse-gas pollution. Meanwhile, White House advisers are debating whether the U.S. should pull out of the Paris Agreement altogether, a step that would undermine other nations’ voluntary efforts to curb carbon pollution.

There’s more. According to news reports, Trump plans to lift a moratorium on federal coal leasing; dump regulation­s on oil industry methane pollution, a strong, if relatively short-lived greenhouse pollutant; and slash Environmen­tal Protection Agency staffing and funding. He has been stocking his administra­tion with climate change skeptics.

If there’s any good news for the planet, it’s that Trump is president and not emperor, so the public, legislator­s, states and environmen­tal groups have plenty of ways to push back against his anti-environmen­tal agenda. Redrafting the fuel economy standards and Obama’s Clean Power Plan would require a lengthy regulatory process followed almost certainly by legal challenges.

Shortly after Trump was elected, the president told The New

York Times reporters and editors he had an “open mind” about climate change and the role of burning fossil fuels. His actions since then, however, suggest otherwise.
