Revelle, Roger R. -
(1909-1991): American geologist and geophysicist. He was a professor at the University of California, co-founder of the UC San Diego campus, director of Scripps Institution of Oceanography (SIO) from 1950-1964, and director of the Institute for Population Studies at Harvard from 1964-1976. He led SIO into world-wide ocean exploration using an expanding fleet of ocean-going ships. In the 1950’s Revelle recognized the importance of studying the Earth’s carbon cycle and the impact of the emission of carbon dioxide by the activities of a growing human population, a process that he described as a "large-scale one-time geophysical experiment" with "the entire planet as laboratory."
