Almost 80 years ago, on April 1938, an English steam and combustion engineer and amateur weather-watcher, published a paper in the Quarterly Journal of the Royal Meteorological Society. His name was Guy Stuart Callendar and his paper, titled “The artificial Production of Carbon Dioxide and its Influence on Temperature”, was going to be one of the most influential papers on climate change science.
Born in Canada in 1898, Callendar earned a certificate in Mechanics and Mathematics in 1922 at City & Guilds College and at the time he published his seminal paper was employed as a steam technologist by the British Electrical and Allied Industries Research Association. A keen meteorologist, interested in climate, Calendar spent his spare time gathering temperature and weather data from around the world. He made all the calculations by hand in his home, in West Sussex, England, and his measurements were so accurate that “they were used to correct the official temperature records of central England”.
