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)
