Gilbert Norman Plass (22 March 1920, in Toronto – 1 March 2004, in Bryan, Texas) was a Canadian physicist who in the 1950s made predictions about the increase in global atmospheric carbon dioxide (CO2) levels in the 20th century and its effect on the average temperature of the planet that closely match measurements reported half a century later.[2]

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 (Manhattan District) 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 (now called Infrared Physics and Technology). In 1963, he accepted a position as the first professor of atmospheric and space science at the Southwest Center for Advanced Studies (now the University of Texas at Arlington), 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.

Carbon dioxide research

In 1953 Plass told Time Magazine of his work on the effects of CO2 from industrial sources as a greenhouse gas, and the potential implications of an increased concentration of carbon dioxide in the atmosphere for global warming. He said "At its present rate of increase, the CO2 in the atmosphere will raise the earth's average temperature 1.5° Fahrenheit every 100 years. ... for centuries to come, if man's industrial growth continues, the earth's climate will continue to grow warmer."[3] From 1956 onwards he published a series of papers on the topic, partly based on advanced calculations of the absorption of infrared radiation, and he made use of early electronic computers. Plass predicted that a doubling of CO2 would warm the planet by 3.6 °C, that CO2 levels in 2000 would be 30% higher than in 1900 and that the planet would be about 1 °C warmer in 2000 than in 1900. In 2007 the IPCC Fourth Assessment Report estimated a climate sensitivity of 2 to 4.5 °C for CO2 doubling, a CO2 rise of 37% since pre-industrial times and a 1900-2000 warm-up of around 0.7 °C.[2][4]

Other work

Plass was an avid philatelist,[1] and founded the United States Possessions Philatelic Society in 1978. He then served as the editor of their journal, Possessions, for 14 years.[5] He also hosted a classical-music oriented radio program called Collector's Choice on KAMU-FM for 20 years. [6] The award-winning Collector's Choice was created by Sunny Nash, KAMU-FM's first program director after the National Public Radio, (NPR)-affiliated station, signed on the air in 1977, also the year Nash graduated from the Texas A&M University Department of Journalism.[7]
