Published July 1988 through June 1999



Item #d93nov132

CO2 increase stalls: Data presented by David Keeling at a meeting last summer show a dramatic drop in the rate of increase of atmospheric CO2 which seemed to coincide with the eruption of Mount Pinatubo. This outcome may hold valuable lessons on the carbon cycle, discussed by J.L. Sarmiento in Nature, pp. 697-698, Oct. 21.

Item #d93nov133

Antarctic ice: Glaciologists at a September meeting in Cambridge, UK, discussed why an ice stream in the Antarctic has stopped moving. (See ibid., pp. 608-609, Oct. 14 1993.) The problem also interests climatologists because of implications for ice sheet stability under climate change. A letter on the latter topic appears ibid., p. 766, Aug. 26.

Item #d93nov134

Ocean mixing: Recent field measurements confirm suspicions that vertical mixing in the ocean occurs very slowly. (See Science News, p. 117, Aug. 21 1993, and: "Variations in Snow on Sea Ice: A Mechanism for Producing Climate Variations," T.S. Ledley, ibid., 98(D6), 10,401-10,410, June 20, 1993).
