Americans understood climate change decades ago

In the 1960s, Americans across various sectors, including government and media, were aware of climate change, contrary to recent Supreme Court opinions.

Kate Yoder reports for Grist.


In short:

  • Historian Naomi Oreskes uncovered evidence that scientists, Congress and even magazines like Sports Illustrated discussed climate change before 1970.
  • A forthcoming paper reveals more than 100 congressional hearings on CO2 and climate issues before the Clean Air Act's enactment.
  • The research challenges current legal interpretations, suggesting Congress intended to empower the EPA to regulate greenhouse gases.

Key quote:

“We discovered a universe of discussions by scientists, by members of Congress, by members of the executive branch.”

— Naomi Oreskes, historian of science at Harvard University

Why this matters:

This research highlights a forgotten history of climate awareness, challenging narratives that downplay past knowledge and intent. Recognizing this history could inform current legal and policy debates about climate regulation.
