At Quadrant we respect winners, so hats off to newly-elected Australian Academy of Science Fellows, Professors Neville Nicholls and Ian Allison. Both are climate catastrophists, each seemingly oblivious to the empirical research which has downgraded the CO2 climate-sensitivity guesstimate (i.e. positive feedback number) from the IPCC’s 1.5-4.5 times to barely more than unity.
These real-world observations suggest that a doubling of atmospheric CO2 from pre-industrial levels would generate, all things being equal, a beneficial increase of about 1degC in warming, not the supposed life-frying 4-6deg rise by 2100 on which the whole multi-trillion-dollar climate scare is based.
The IPCC’s fantasy figure for sensitivity to CO2 is one of the reasons why 111 of its 114 climate model runs over-estimated the negligible warming in the 15 years to 2013. However, the main reason why the climate models are duds is that the very notion of complex and chaotic climate forces being controlled by a simple CO2-emissions dial is laughable.
