Gilbert Plass

Who was Gilbert Plass?

Gilbert Norman Plass was a Canadian physicist who in the 1950s made predictions about the increase in global atmospheric carbon dioxide levels in the 20th century and its effect on the average temperature of the planet that closely match measurements reported half a century later.

Plass worked most of his life as a physicist in the United States. He graduated from Harvard University in 1941 and earned a PhD in physics from Princeton University in 1947. He worked as an associate physicist at the Metallurgical Laboratory of the University of Chicago from 1942 to 1945. He became an instructor of physics at Johns Hopkins University in 1946, and eventually became an associate professor there. In 1955, leaving academia, he held a job for a year as a staff scientist with Lockheed Aircraft Corporation. He then joined the advanced research staff at the Aeronutronic division of the Ford Motor Company. In 1960, he became manager of the research lab at Ford’s theoretical physics department and a consulting editor of the journal Infrared Physics. In 1963, he accepted a position as the first professor of atmospheric and space science at the Southwest Center for Advanced Studies, where he remained for five years. In 1968, he arrived at Texas A&M University, where he served as professor of physics and head of the department.
