Eunice Newton Foote
Eunice Newton Foote (born Eunice Newton; July 17, 1819 – September 30, 1888) was an American scientist, inventor, and women's rights campaigner. She was the first scientist to identify the insulating effect of certain gases and to posit that therefore rising carbon dioxide (CO2) levels could increase atmospheric temperature and affect climate, a phenomenon now referred to as the greenhouse effect.
