What Climate Change Looked Like in the Summer of ’69

It was 1969, my final year as a Geography and Applied Climatology student at Edinburgh University. The popular scientific consensus (what they taught all us Baby Boomers) was the CO2 levels building in the atmosphere would reflect the Sun’s rays and cause a great global cooling. Yep, we were headed for another ice age. And they wanted to cover the polar ice caps with soot to start them melting. No joke!
