Happy birthday to #geochemist Charles David Keeling (1928 - 2005) whose decades long observations of CO2 in air samples from Mauna Loa Observatory were some of the 1st direct data to show the human contribution to greenhouse effect & global warming. The ‘Keeling Curve’ (in copper & red) shows both the seasonal variations (the wiggles) & the strong upward trend with time as the greenhouse gas built up in the atmosphere. 🧵

For #printerSolstice prompt carbon: my #linocut portrait of Japanese #geochemist Katsuko Saruhashi (1920-2007) who created tools that allowed her to make 1st measurements of CO2 in seawater, raised alarm about nuclear fallout, tracing it in oceans & researched peaceful uses of nuclear power. A supporter of women in science, she established the Society of Japanese Women Scientists & the Saruhashi Prize for Japanese women🧵
