"A few years before his death, [[Joseph Fourier]] (1768–1830), a [[French]] mathematician, was the first scientist to realize that **the atmosphere absorbs some of the radiation emanating from the ground**; "and in 1856, [[Eunice Foote]], an [[American]] scientist and inventor, was the first author to **link** (briefly but clearly) **CO2 with global warming**. "Five years later, [[John Tyndall]] (1820–1893), an [[English]] physicist, explained that **water vapor is the most important absorber of the outgoing radiation**, which means that “**every variation of this constituent must produce a change in climate**”—and he added that “**similar remarks would apply to the carbonic acid diffused through the air**.” Concise but clear, when rephrased in modern parlance it says: **increases in CO2 concentration must produce rising atmospheric temperature**."
