It’s fairly likely that 100% of people sharing a common delusion will agree with each other.
An example of such a delusion might be where otherwise sane and rational people believe that radiation absorbed by CO2, resulting in heating of the gas, is somehow multiplied and retransmitted, resulting in more energy exiting the gas than was absorbed. The deluded resort to all sorts of physically nonsensical justifications to account for ignoring the laws oh thermodynamics.
For example, they will say that radiation from the ground, say, provides additional energy, which is perfectly true, and perfectly misleading. They purposely forget to mention that when the ground loses energy, its temperature drops.This is demonstrated in practice at night. There’s no such thing as a free lunch, where energy is concerned.
Attempts to confuse the issue by using terms such as Transient Climate Sensitivity or Equilibrium Climate Sensitivity, merely serve to reinforce the delusional thinking. It will be noted that climate is the average of weather, and, as such, is not sensitive to anything other than weather history, being a mathematical average of something which has already occurred.
One might as well claim authority for the existence of phlogiston, the aether, or the indivisibility of the atom, based on majority acclamation for these ideas.
Maybe the concern about the percentage of people believing in this fantasy, or that fantasy, is misplaced. One cannot cure psychosis by rational discussion, regardless of the impression given by TV shows.
Maybe we’re all destined to death by slow boiling, but after four and a half billion years of sunshine falling on the Earth without it heating up at all, the prospect looks unlikely to me.
Cheers.
