EPA administrator Pruitt wants to “Red Team” the catastrophic anthropogenic global warming (CAGW) consensus best reflected in the IPCC assessment reports (AR). At its core, CAGW rests on just three propositions:
1. CO2 is a ‘greenhouse’ gas retarding radiative cooling. This should not be in serious dispute since Tyndall experimentally proved it in 1859.
2. The Earth is warming. Although the details are in dispute because of temperature data quality problems and ‘adjustments’, the general fact is not. The Earth has been intermittently warming since the Little Ice Age (LIA) ended. For example, the last Thames Ice Fair was in 1814.
3. CO2 and its knock-on effects caused the recent warming, and climate models (such as the CMIP5 archive for IPCC AR5) predict this will continue to catastrophic levels. This is an extremely dubious proposition.
This guest post addresses proposition 3. It does so in…
