This week, we present a bonus episode of Warm Regards.

Forty years ago, on April 28th, 1975, Newsweek magazine published an article that created one of the most pervasive scientific myths in modern history.

It was a one-page story, buried in the middle of the magazine. But it became the most widely cited article in Newsweek’s history.

The piece, called “A Cooling World," raised concerns about a global cooling trend.

It was published on page 64. But it became front page news for climate skeptics, who point to it as proof that scientists were confused, or even deliberately misleading, about global warming.

In this episode, producer Stephen Lacey revisits the myth 40 years later.
