Lukewarmers seem to believe in the impossible, but only a little bit.
Apparently, GHG’s warm the atmosphere, but not very much. Nobody seems to be sure how much, or to be able to provide experimental proof of this most wondrous effect.
Nobody has managed to employ the supposed effect in any practical way. Given the supposed heat storing and amplifying effects of CO2, a steam car running on heat from a CO2 heat accumulator would be a sure fire money spinner. Cheap energy!
Combined with a supply of phlogiston of suitable negative weight, the vehicle could be made to fly. But phlogiston is silly isn’t it? Quite unlike CO2 which is well known to trap, store, and accumulate heat!
Facts are facts. The Earth has cooled. CO2 warms nothing. A vacuum is the absence of anything, and there is no need for an aether, which had to have more and more magical properties.
As of the late 19th century –
“By this point the mechanical qualities of the aether had become more and more magical: it had to be a fluid in order to fill space, but one that was millions of times more rigid than steel in order to support the high frequencies of light waves. It also had to be massless and without viscosity, otherwise it would visibly affect the orbits of planets. Additionally it appeared it had to be completely transparent, non-dispersive, incompressible, and continuous at a very small scale.”
Lukewarmists would no doubt be arguing about the numerical value of the rigidity, claiming the viscosity was just really small, and that almost incompressible would do.
As it turned out, the aether didn’t exist, and didn’t need to. The finest minds of the time were merely gullible and easily swayed. And so it is today.
CO2 warming? Only believe in it a little bit? Really?
Cheers.
