While asserting that the earth's climate is becoming warmer and sea level is rising, an ad hoc committee of the National Research Council (NRC) recently said that in the next century, the oceans are unlikely to rise as much as some have predicted. The message of their report is that the sea level situation today is “a manageable problem, not a disaster, as far as we can tell at the present time,” according to Mark F. Meier, now of the University of Colorado and recently of the U.S. Geological Survey. Meier served as chairman of the Ad Hoc Committee on the Relationship Between Land Ice and Sea Level of NRC's Polar Research Board. Last month, Meier discussed the report's contents in a public lecture at the National Academy of Sciences in Washington, D.C.
