Global warming hypothesis
The global warming hypothesis was the subject of a lecture delivered by Dr. Gordon McBean, Assistant Deputy Minister, Atmospheric Environment Service[?], to World Meteorological Organization 12th Congress, Geneva, June 16, 1995
Ideas discussed by Dr. McBean:
"The hypothesis that changes in concentrations of greenhouse gases, such as water vapour and carbon dioxide, could cause global warming" (Tyndall, 1861)
"a tripling of CO2 concentrations in the atmosphere could increase the average air temperature of the earth by about 8-9 C [degrees celsius]." (Arrhenius, 1896)
"The current projections are that a doubling of CO2 or equivalent, expected before the end of the next century, would cause an average equilibrium surface warming of 1.5 to 4.5 C." (McBean, 1995)
