  • CLIMATE ENGINEERING

Item #d94mar111

Climate engineering was the subject of a symposium at the annual meeting of the American Association for the Advancement of Science (February, San Francisco). Recent field experiments indicate that the fertilization of ocean plankton with iron, intended to stimulate their growth and removal of carbon dioxide from the atmosphere, is unlikely to be very effective. (See Science, pp. 1089-1090, Feb. 25; Science News, p. 148, Mar. 24.) A scheme to reduce stratospheric ozone loss by injecting massive amounts of ethane or propane into the stratosphere was also pronounced unlikely to be successful. (See New Scientist, p. 13, Feb. 26; Chem. Eng. News, pp. 26-27, Mar. 7.) The latter article gives the broadest coverage of the symposium panel discussion, which included an economist and a philosopher as well as scientists.
