Blaming global warming on humans comes down to two assertions:
Rising CO2 in the atmosphere causes earth’s surface temperature to rise.
Humans burning fossil fuels cause rising atmospheric CO2.
For this post I will not address the first premise, instead refer the reader to a previous article referencing Fred Singer. He noted that greenhouse gas theory presumes surface warming arises because heat is forced to escape at a higher, colder altitude. In fact, temperatures in the tropopause do not change with altitude (“pause”), and in the stratosphere temperatures increase with altitude. That post also includes the “meat” of the brief submitted to Judge Alsup’s court by Happer, Koonin and Lindzen, which questions CO2 driving global warming in the face of other more powerful factors.

The focus in this piece is the claim that fossil fuel emissions drive observed rising CO2 concentrations. IPCC consensus scientists…
