Trump EPA Rollback and the Case for Talking About Pollution, Not Just Climate

At 50:48 · chapter starts 49:20

Dubner circles back to the present: the Trump administration's EPA has announced it will no longer weigh the health benefits of reduced pollution when writing clean air regulations. Greenstone's verdict is unsparing — he says it will go down in history books as a dramatic step backward, leading to dirtier air and more greenhouse gas emissions. Dubner then offers a personal reflection: he's long wondered whether the climate change debate might have unfolded differently if it had been framed as a fight against pollution rather than a fight against CO2. The evidence for pollution's harms — physiological and now cognitive — is so compelling that it crosses political lines. Naturalists and preservationists have historically come from both parties; no one wants their children breathing dirty air. Severnini gets the final word, urging that particulate matter be part of everyday energy and environmental policy conversations.
