In 1938, Guy Callendar was the first person to use observations of temperature from across the world to demonstrate that the land areas were warming.

He also collated CO2 measurements to show that atmospheric CO2 levels were increasing.

And he also showed that the expected warming from the increase in CO2 was at least half of the observed warming.

The theory was understood much earlier, but this was the first attribution of observed climate change.
