May 20, 1959 Times of India letter about Teller and CO2

Sixty five years ago, on this day, May 20th, 1959, the Times of India ran a letter, under the title “Getting Hotter?” by S.B. Kulkarni and R. Mani about Edward Teller’s warning on carbon dioxide.

The amount of carbon dioxide in the air was roughly 315ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The context was that Edward Teller had been talking about CO2 buildup. And this had caught the eye of a couple of people in India who had written letters about it.

What we learn is that people all around the world were aware. They’d already been in January of 1957 the Otago Herald times in New Zealand. 

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.
