The Façade Continues to Crack
...climate models are useless....My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit. Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it. They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy.
Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress.
It was funny to note how characteristically Hansen played the bullying victim Ann Coulter describes so well by claiming he was "muzzled by the Bush administration despite doing 1,400 on-the-job media interviews!" Some muzzle.
Pre-industrialization levels of CO2, say, 280 ppm, produce 95% of the possible 'greenhouse' effect and any increase of CO2 above 280 has almost no effect on mean global temperature. That's an inconvenient rock of a fact on which Gore's and Hansen's fantasy ship of anthropogenic global warming has struck and is rapidly foundering.
