Don't hyperventilate Jack. Its just a scam. The following should help.

An engine is cooled by transferring energy from water to air. The warmed air is displaced upwards. As it rises its density falls away. That rising air cools via decompression and radiation. It loses the energy it gained from the cars radiator before it reaches an elevation of 10 km, a distance that be walked in an hour and twenty minutes. At that elevation 90% of the bulk of the atmosphere is beneath. The atmosphere is not a sink for energy. Never was and never will be. It very efficiently vents energy.

The land does not absorb energy to depth and by and large it loses that energy overnight.

The ocean is a sink for energy. It is where the air tends to descend in high pressure cells that are variably extensive and largely cloud free because the air is compressed as it descends, becomes warmer and its relative humidity falls away. The prime source of ascending air to feed the mid latitude high pressure cells over the oceans can be found in the near polar regions in winter where the partial pressure of ozone increases and especially so as the sun sinks to the horizon or disappears below it so that the quotient of ozone busting UV radiation is diminished. Ozone busting oxides of nitrogen descend from the mesosphere greatly influenced by waxing and waning solar phenomena. It’s the so called ‘polar cyclones’ associated with the presence of ozone at the elevation of the upper troposphere and the jet stream that drive the high latitude ascent that feeds into the mid latitude descent driving change in cloud cover over the oceans. In this manner the Earths energy budget is altered. The influences of man and the energy absorbing and warming influence of carbon dioxide and water vapour are insignificant and minor players, if players they be at all, in the grand scheme of things.

You’re just describing normal atmospheric convection. None of it touches the radiative physics of CO₂, which is the core of the greenhouse effect. There’s no argument here, just unrelated observations.

The atmosphere is a dissipative medium. It cools the sunlit surface regardless of the source of the energy that warms the surface air. Speedily, in a matter of hours.

I read Juice, by Tim Winton, last week. It's a guide to life designed by these fuckers - horrific, Hobbesian, no place for those without very high practical skills and sound judgement. These fuckers don't have a chance, nor their pampered kids. But who'd want to survive anyway? We're not, en masse, going to get our act together. Murdoch's done his lethal lobotomising too well, corporations have bought the political class. System apparatchiks haven't worked out they're fucked too yet. Disruption, revenge, sabotage - yes in North America, nah, not in 'Strayia, not till Twiggy, Ian Dunlop, Cannon-Brookes get themselves to the front of a march across the harbour bridge.
