William Connelly has a translation of Fourier's ideas at http://www.wmconnolley.org.uk/sci/fourier_1827/fourier_1827.html#text as does Pierrehumbert, but it would be interesting to know what De Saussure, Poulliet, & Hopkins had to say :-) Of course Tyndall was mainly concerned with the short term effects of green house gases. Arrhenius was the first to investigate global warming, and he chose a doubling of CO2 as the standard, which has led unconsciously to the view that we need not worry until CO2 has exceed that value :-( His paper is here: http://web.lemoyne.edu/~giunta/Arrhenius.html Another paper which has just become available is Callendar's paper the first re AGW.
