How the Female Scientist Who Discovered the #GreenhouseGas Effect Was Forgotten by History

"In the early 19th century, Aristotle’s Meteorologica still guided scientific ideas about the climate. The model 'sprang from the ancient Greek concept of klima,' as Ian Beacock writes at The Atlantic, a static scheme that 'divided the hemispheres into three fixed climatic bands: polar cold, equatorial heat, and a zone of moderation in the middle.' It wasn’t until the 1850s that the study of climate developed into what historian Deborah Cohen describes as 'dynamic climatology.'
"Indeed, 120 years before #ExxonMobile learned about — and then seemingly covered up — #GlobalWarming, pioneering researchers discovered the greenhouse gas effect, the tendency for a closed environment like our atmosphere to heat up when carbon dioxide levels rise. The first person on record to link CO2 and global warming, amateur scientist #EuniceNewtonFoote, presented her research to the Eight Annual Meeting of the American Association for the Advancement of Science in 1856.
"Foote’s paper, 'Circumstances affecting the heat of the sun’s rays,' was reviewed the following month in the pages of Scientific American, in a column that approved of her 'practical experiments' and noted, 'this we are happy to say has been done by a lady.' She used an air pump, glass cylinders, and thermometers to compare the effects of sunlight on 'carbonic acid gas' (or carbon dioxide) and 'common air.' From her rudimentary but effective demonstrations, she concluded:
" 'An atmosphere of that gas [CO2] would give to our earth a high temperature; and if as some suppose, at one period of its history the air had mixed with it a larger proportion than at present, an increased temperature…must have necessarily resulted.'
"Unfortunately, her achievement would disappear three years later when Irish physicist #JohnTyndall, who likely knew nothing of Foote, made the same discovery. With his superior resources and privileges, Tyndall was able to take his research further. 'In retrospect,' one climate science database writes, Tyndall has emerged as the founder of climate science, though the view 'hides a complex, and in many ways more interesting story.' "
