DIED. CHARLES DAVID KEELING, 77, tenacious climate scientist and conservationist whose precise measurements of carbon dioxide in the atmosphere over five decades became the undisputed basis for global-warming concerns; of a heart attack; in Hamilton, Mont. Although many had previously assumed that the oceans and plants would absorb all the gas emissions from cars and factories, his so-called Keeling Curve, which since the mid-1950s has charted steady increases in carbon dioxide in the air, clearly linked the pattern to humans' increased consumption of fossil fuels, which release carbon dioxide when burned...
