claim: when 3 per cent of total annual global emissions of carbon dioxide are from humans and Australia prod­uces 1.3 per cent of this 3 per cent, then no amount of emissions reductio­n here will have any effect on global climate.
evidence: Lindzen has stated that due to the non-linear effects of carbon dioxide in the atmosphere, CO2 levels are now around 30% higher than pre-industrial levels but temperatures have responded by about 75% 0.6 °C (1.08 °F) of the expected value for a doubling of CO2.
