May 6, 1977 – Bert Bolin article in Science about increased atmospheric CO2 concentrations owing to forestry and agriculture

Forty seven years ago, on this day, May 6th, 1977, Swedish scientist Bert Bolin sounded a warning about other sources (besides burning oil, coal and gas) leading to more CO2 in the atmosphere.

Source – https://www.science.org/doi/pdf/10.1126/science.196.4290.613?casa_token=uAeo-ORaYTsAAAAA:IXMCd01f0aXX1KI_4E-_7x6PZC5_KW3MFgSHKAmDJ9wrZz1GMxc_o0Ga0glPcnCvHTBjvTYBpVnn

The amount of carbon dioxide in the air was roughly 334ppm. As of 2024 it is 425ppm, but check here for daily measures. 

The context was that Bolin had been looking at carbon dioxide buildup and its consequences since the late 50s. There were concerns about food production; these had been voiced publicly by Henry Kissinger in 1974. And other work was ongoing about that. What Bolin was doing here was pointing out how deforestation and agriculture might be contributing to CO2 build up alongside the vast increases in fossil fuel burning for energy production.

 What we learn is Bolin was a mensch and that people reading science knew what was going on.

What happened next? Bolin ended up as the first chair of the IPCC and lived long enough to see the Nobel Prize and died shortly after that in 2007.

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.
