That correction, which sits at the foot of the story, dutifully straightens out the record. Yet given the magnitude of the screw-up, it should sit atop the story, surrounded by red flashing lights and perhaps an audio track to instruct readers: Warning: This story once peddled a faulty and damaging premise.

That premise suggests that the Trump administration is stifling a damaging draft report — part of the congressionally mandated National Climate Assessment — with dire warnings about climate change. “The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration,” noted the lead of the article, which was written by Lisa Friedman.
