Global Warming Predicted 82 years ago: G S Callendar

I’m getting interested in Guy Stewart Callendar, an English/Canadian meteorologist who demonstrated global warming as early as 1938. He collected data from world weather stations to show that temperatures had risen by over 0.3 degrees in the previous 50 years, and he correctly explained this as due largely to the burning of fossil fuels. which had concentrated carbon dioxide concentrations in the atmosphere. Although this spurred more research, sadly it was ignored at large until the 1960s and 70s when anxiety about future climate change began to figure in public opinion, and politicians were the last to act.
