Why Skeptics Need a "Greenhouse Effect"

The Basic Postulate of CO2 alarmism is the existence of no-feedback climate sensitivity of global warming of 1 C as the result of a "Greenhouse Effect" from doubling of atmospheric CO2, which by postulated positive feedback is increased to an alarming 3 C.

Leading skeptics including Dick Lindzen, Fred Singer and Roy Spencer applauded by Lord Monckton and Anthony Watts, start from the same Basic Postulate of 1 C and their skepticism is expressed by negative feedback instead of the positive feedback of alarmism, reducing climate sensitivity to harmless 0.5 C. The trademark of their skepticism is thus negative feedback.

In recent posts I have documented an attack by this leading group of skeptics on other skeptics including myself, which question the Basic Postulate. I have asked for reasons for this form of auto-immune reaction and have by a commenter been led to the following answer:

Lindzen at al have invested heavily in negative feedback as special scientific competence, which however is not really needed without the Basic Postulate. The relentless attack can thus be understood as a reptile brain reaction under a perceived threat to core values, a threat which is not real because the real threat is CO2 alarmism and not skepticism to its Basic Postulate.
