On this day, December 22 in 1975, the New York Times ran a story “Scientist Warns of Great Floods if Earth’s Heat Rises.”
But carbon dioxide was not in the frame.
Dr Howard Wilcox, who had a book called “Hothouse Earth” argued that – in the words of the NYT-
“man’s output of heat into the atmosphere, if allowed to increase at present energy and industrial growth rates, will raise the earth’s temperature enough to melt the polar ice caps and flood many populous areas of the earth in the next 80 to 180 years.”
That ‘heat’ would be the key driver, was not the case…, as both William Kellogg and Murray Mitchell pointed out – the final paragraphs in the story are these:
Dr. J. Murray Mitchell, Jr.; senior research climatologist at the National Oceanic and Atmospheric Administration laboratory in Silver Spring, Md. in a telephone interview offered, similar observations:
“I agree with Dr. Wilcox’s concern and his scientific analysis and statistical evidence. But I feel that the more immediate danger will come from the increasing amounts of carbon dioxide that are thrown off into the atmosphere along with the heat that Dr. Wilcox talks about.”
Baynard Webster, “Scientist Warns of Great Floods if Earth’s Heat Rises,” New York Times, December 22, 1975
[The amount of carbon dioxide in the atmosphere was 331ppm. At time of writing it was 419ishppm- but for what it is now,well, see here for the latest.]
Why this matters
We need to remember that – as per the Landsberg article mentioned a few days ago, carbon dioxide was not the only villain in the picture.
What happened next
Within a couple of years, it was obvious that carbon dioxide was, in fact, the big thing to worry about.
