California's Senate Concurrent Resolution 99 honors "the life and legacy of Eunice Newton Foote" and proclaims July 17, 2025, as Eunice Newton Foote Day.
The resolution describes Foote (1819-1888) as "a principal activist in the women's rights movement, an inventor, and a groundbreaking scientist whose work helped establish the field of climate science," and her 1856 paper "Circumstances Affecting the Heat of the Sun's Rays" as "the first published work to recognize climatic warming caused by an increased proportion of carbon dioxide in the atmosphere."
Introduced by Ben Allen (D-District 24), the resolution was adopted by the Senate on July 17, 2025, and then by the Assembly on August 21, 2025.
