LMAO. Here's another guy you've never heard about. 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." [2] 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.
