July 19, 1977 – American public hears from a climate scientist

Forty seven years ago, on this day, July 19th, 1977 , Stephen Schneider lays it out.

Appearing on the Johnny Carson Show on July 19, 1977 a year after the original release of The Genesis Strategy, Schneider responded to a series of questions regarding the ability of scientists to predict the weather more than a few days in advance, a prospect that – given his experiences with Kellogg and Smagorinsky early in his career – appeared entirely possible. Other conversation topics ensued, including issues of drought, whether the climate was cooling or warming, and even whether a recent weather fluctuation caused a serious black out in New York City. Given what appeared to be signs that society was increasingly sensitive to even small-scale environmental challenges, Schneider argued for building further resilience into society. “The laws of nature frequently are not in line with some of our laws,” he stated in an attempt to distinguish between natural laws – which are stable and enduring – and man-made laws – which tend to be short-sighted, sporadic, and clumsy. Everything in human decision making, he believed, is a trade-off between risks and benefits and therefore decisions require the incorporation of value judgments to maximize margins of safety in spite of  existing uncertainties.55

The amount of carbon dioxide in the air was roughly 332ppm. As of 2024 it is 426ppm, but check here for daily measures. 

The context was that Stephen Schneider was already well known because of his ice age prediction in 1971. He had just published The Genesis Strategy with co-author Lynne Merizow. Him being on Carson was a big deal, though. I think this is the first time he was on. 

What we learn is that a small number of scientists were trying to communicate this stuff. early on. 

What happened next: Schneider committed a faux pas by going off script and Carson never had him on again. Schneider kept being a public intellectual public figure. He was really good at what he did. RIP Stephen Schneider.

What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
