AP Success - AP World History: Greenhouse Effect: Historical View
"Atmospheric monitoring programs show that the level of carbon dioxide in the atmosphere has increased about 8% over the last twenty-five years and now stands at about 340 parts per million . . .The carbon dioxide content of the atmosphere is of concern since it can affect global climate . . . Mitigation of the “greenhouse effect” would require major reductions in fossil fuel consumption. . . Overall, the current outlook suggests potentially serious climate programs are not likely to occur until the late 21st century."
M.B. Glaser, Manager, Environmental Affairs Programs, Exxon Research and Engineering Company, “CO2 Greenhouse Effect,” November 12, 1982
