An open letter challenging the EPA on CO2 regulation

WUWT
"EPA’s CO2 Regulations are NOT Based on Sound Science Bottom –Line: No scientist or team of scientists has come up with an empirically validated theory proving that higher Atmospheric CO2 Levels will lead to higher GAST–not EPA’s team and certainly not to the EPA’s 90-99% certainty. Moreover, if the causal link between higher atmospheric CO2 concentrations and higher GAST is broken by invalidating EPA’s Three LoE, then EPA’s claim that higher CO2 concentrations also cause sea level increases and more frequent and severe storms, floods and droughts is also disproved. Such causality claims require a validated theory that higher CO2 concentrations cause increases in GAST. Lacking such a validated theory, EPA’s entire house of cards collapses.
More generally, EPA violated both the scientific method and the Scientific Advisory Board statute intended to enforce the scientific method when it made its highly influential scientific assessment in the Endangerment Finding."
