Guy Callendar

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.

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...

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
