President Donald Trump’s latest climate rollback makes it all but official: The United States is giving up on trying to stop the planet’s warming.

In some ways, the effort has barely started.

More than 15 years after federal regulators officially recognized that greenhouse gas pollution threatens “current and future generations,” their most ambitious efforts to defuse that threat have been blocked in the courts and by Trump’s rule-slicing buzzsaw. Wednesday’s action by the Environmental Protection Agency would extend that streak by wiping out a Biden-era regulation on power plants — leaving the nation’s second-largest source of climate pollution unshackled until at least the early 2030s. Rules aimed at lessening climate pollution from transportation, the nation’s No. 1 source, are also on the Trump hit list.

Meanwhile, the GOP megabill lumbering through the Senate would dismember former President Joe Biden’s other huge climate initiative, the 2022 law that sought to use hundreds of billions of dollars in tax breaks and other incentives to encourage consumers and businesses to switch to carbon-free energy. At the same time, Trump’s appointees have spent months shutting down climate programs, firing their workers and gutting research into the problem, while making it harder for states such as California to tackle the issue on their own.
