Methane Hydrates in Quaternary Climate Change The Clathrate Gun Hypothesis. James P. Kennett, Kevin G. Cannariato, Ingrid L. Hendy, and Richard J. Behl. American Geophysical Union, Washington, DC, 2002. 224 pp. Paper, $42.00. ISBN 0-87590-296-0.

Using data from paleooceanography, climate dynamics, paleobotany, marine geology, and biogeochemistry, the authors argue that the remarkably abrupt global warmings during the ice ages (including that which terminated the last one) were caused by the destabilization of the reser-voir of methane hydrates frozen in ocean sediments.
