On this day, in 1861, Irish scientist John Tyndall read his paper about carbon dioxide at the Royal Society at the annual Bakerian lecture. Tyndall was not, we now know, the first person to point out what he called carbonic acid had greenhouse water warming potential. That honour belongs to Eunice Foote in the United States a few years earlier. There’s an interesting and useful summary of this at the beginning of Alice Bell’s excellent 2021 book “Our Biggest Experiment.” And of course the idea that there must be something, some gas, keeping the planet warmer than it otherwise would be dates back to Fourier in 1824.
Tyndall did the research, reported it. It wasn’t for another 35 years that someone, Svante Arrhenius. said, “this is in fact going to be a thing (but not for centuries, and it will be a good thing.”. He was trying to distract himself from a messy divorce by doing laborious calculations, which your mobile phone could probably do in about three seconds now.
Why this matters,
We’ve understood the science – this is 19th century physics – for a very long time. Unfortunately, we have not acted. And as I’ve said before, I will say again, that “we” first person plural pronoun is doing a lot of work in that sentence.

What happened next
The Tyndall Centre got set up in 2000.
