an early predictor of global warming, Roger Revelle helped to start the scientific debate on the issue in the late 1950s. He challenged the accepted notion that global warming was countered by the absorption of carbon dioxide from the oceans. Revelle discovered that the particular chemistry of sea water hinders such absorption. Because of the respect that he earned among the scientific community, Revelle was regarded as a spokesperson for science whose advice on as diverse matters as world population, agricultural policies, education, and the preservation of the environment were held in high esteem.
Born in Seattle, Washington, on March 7, 1909, Revelle was raised in Pasadena, California, and soon stood out as a gifted student during his academic career. In 1925, Revelle enrolled at Pomona College with an interest in journalism, but later switched to geology as his major field of study. In 1928, Revelle met Ellen Virginia Clark, a student at the neighboring Scripps College and a grandniece of Scripps College founder Ellen Browning Scripps. The couple married in 1931.
Revelle obtained his bachelor's degree from Pomona in 1929, and then entered the University of California-Berkley to pursue his studies in geology. In 1931, his professor George Davis Louderback recommended him for a research assistantship in oceanography at the Scripps Institute of Oceanography in
