Not going to bother checking exactly how long because you will just cover it up. You must explain how I can cover something up that you publicly release.

Wrong. Acidification as used by you maybe. You should read up on titration. Acidification is making a base acidic, not less alkaline,

Everything is dead easy if you are brain dead. Wink

Nice ad hom there!

Acidification—making a base more acidic, less alkaline. Increasing the H+ ion count.

In a solid object not made of metal heat cannot be conducted or convected away. The solid object, the surface of the earth, can only radiate excess heat away.

Incorrect.

Solids can conduct heat, and do so via kinetic energy at the atomic level.

Any physics textbook can illustrate this should you wish to learn more.

E.g. at 1.2metre depths the soil is at a constant temperature. Touch a rock that has been in the sun then touch a metallic object that has also been in the sun—feels hotter because it conducts more heat to your hand.

Such a little word "much". Glass is an insulator. Glass conducts heat, not well, but conduct it does. And it is not a metal.

How can that conduct heat when a whole huge area is at the same temperature? Nah, radiation is the only way the surface of earth can lose heat, but increasingly the IR radiation is redirected back to the surface.

York Peninsula say, or Eyre Peninsula or the Lower North of SA etc. Hell, in summer almost all of Australia is at one temperature, too bloody hot. Where is the desert around Uluru going to conduct heat too, equally hot deserts further out from Uluru?

Insulators don’t move heat around much at all, the surface can only lose heat by radiation.

Even the seas can’t get rid of heat much except by radiation. While molecules in a fluid move much faster than molecules in a solid the options are limited there too. Looking at heat maps you see huge swathes of ocean are pretty much the same temperature (pretty much, doubt really detailed fine–grained temperature records are available) such as “hot waters on the eastern side of the Pacific etc so conduction is out. Convection doesn’t come into it. Some heat might be lost to deep ocean waters but studies indicate there isn’t much mixing. While oceans can lose heat to the air or by condensation (latent heat) again most is directly or indirectly (air heated by the warm ocean) lost by radiation.

Sorry, Sore End, but it bloody well is.

La Nina years here are now hotter than El Nino years were just 2-3 decades ago.

Here, measurements of IR being sent back down to the surface as CO2 increases. So accurate, you can see the carbon cycle:

Since the surface cannot radiate away all its heat it necessarily heats up.

Really. It was 12ºC here today. What parts of York peninsula was at 12ºC? Eyre Peninsula? Lower North of SA. Or are you talking about homogenised temperatures?

Give us the data for these places. maybe you are talking about homogenised temperatures where they are for areas of 12,000 sq km, not actual place temperatures.

Yeah, you would be stupid enough to believe that.

The temperatures for Kimba, Port Lincoln, Elliston all seem to be different. How is that?

Darwin, Perth, Hobart, Sydney all different. Grin

But in defined bands, huge swathes of sea. Or do you think waters north of Australia can conduct heat to waters south of Tasmania? Each huge temperature band is surrounded by other bands of water of similar temperature. Nope, even the seas effectively can only radiate away energy.

Your problem is an inability to think.
