Fourier made similar discoveries a few decades before - at least in terms of co2's climate warming potential.
But yeah, women have been written out of the history of scientific discovery so Eunice Foote should be recognised. Joseph Tyndall also made similar discoveries at the same time. People do independently arrive at the same conclusions.
No idea what is going on here but maybe she was just moved location for a few days and carried with her a few changes of clotehes etc.
Edit - I am not claiming there isn't a conspiracy happening. Just that maybe the white box of shit a convict carries from one location to the other might not be it.
If there is a bigger conspiracy do not be distracted by a white fucking box.
