Three Climate Change Pioneers
From BBC Ideas, the story of three people who pioneered the science of climate change — Eunice Foote, Guy Stewart Callendar, and Charles Keeling — each of whom was under-recognized for their achievements at the time.
In particular, Eunice Foote demonstrated the greenhouse effect all the way back in 1856, but her contribution was lost to time and science until very recently.
Looking back on Earth’s history, Foote explains that “an atmosphere of that gas would give to our earth a high temperature … at one period of its history the air had mixed with it a larger proportion than at present, an increased temperature from its own action as well as from increased weight must have necessarily resulted.” Of the gases tested, she concluded that carbonic acid trapped the most heat, having a final temperature of 125 °F. Foote was years ahead of her time. What she described and theorized was the gradual warming of the Earth’s atmosphere — what today we call the greenhouse effect.
