1938 After something of a hiatus in climate change research (with some notable exceptions), Guy Callendar published a paper showing the link between observed rising carbon dioxide concentrations in the atmosphere and observed global mean surface temperature. 4/

In September 1933, American meteorologist Joseph Kincer asked a simple question: is the climate changing? So began the effort to understand the scope of humanity’s interference with the climate. theconversation.com/cop29-how-fa...

The first scientific paper highlighting the observed rise in global temperatures was in 1938. By me! And I also linked the observed warming to the rise in CO2 levels in the atmosphere, building on the earlier theoretical work. We have known all this for soooo long.

On a Wednesday in February 1938, Guy Stewart Callendar stood before a group of leading scientists, members of the United Kingdom’s Royal Meteorological Society. He had a bold idea to share: Humans’ burning of fuel was making the planet warmer. nautil.us/the-part-tim...

A brief history of climate science: 1822 - Joseph Fourier suggests the atmosphere behaves like a greenhouse 1857 - Eunice Foote suggests that CO₂ is the gas responsible 1861 - John Tyndall identifies the main greenhouse gases which absorb infrared radiation: H₂O, CO₂, CH₄
