A scientist can observe “huge volumes” of CO2 and not show much interest in estimating the size of the discharge, yet other supporters of AGW do not hesitate to run models and publish estimates of this or that effect down to three or four significant digits of accuracy based on rough estimates of CO2. Then politicians take these numbers as gospel and base draconian legislation on them like “cap and trade”, a plan that will destroy new business formation in the US.
Pitiful on several counts.
