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 ." (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)
