The models/simulations are falsified by the evidence:

Notice that that darkens the planet's albedo, accelerating the progression of ClimatePunctuation/GlobalWarming...

and that the models/simulations contradict the evidence, saying that what happened wouldn't happen.

The real & correct prediction is that we have already put 5-6C global-warming's worth of CO2 into the atmosphere, AND we have also added other greenhouse gasses, like methane, & sulfur-hexafluoride.

Here is the robust fact:

The powerlaw they discovered that governs the interglacial temperatures is this:

280ppm is a good pre-industrial CO2 measure.

• 280ppm * (9th-root-of-2) == +1C
• 280ppm * (9th-root-of-2)^2 == +2C
• 280ppm * (9th-root-of-2)^3 == +3C
• 280ppm * (9th-root-of-2)^4 == +4C
• 280ppm * (9th-root-of-2)^5 == +5C ( we are at 421, which is above this )
• 280ppm * (9th-root-of-2)^6 == +6C
• 280ppm * (9th-root-of-2)^7 == +7C
• 280ppm * (9th-root-of-2)^8 == +8C
• 280ppm * (9th-root-of-2)^9 == +9C ( aka 280ppm * 2 == +9C )

At that point, the CO2 level has been doubled.

CO2 acts like the Gate in a bipolar transistor: the tiny current you put into the gate, the HUGE current flows through the Source-Drain part of the transistor.

Increase the CO2, & that increases the moisture in the atmosphere, which MASSIVELY increases the amount of retained solar heat.

Pretending that +2C is attainable, now, is delusional.

I'm no longer certain that there will be ANY life around the equator, in 1 century, at or near the surface.

Cmon, even before the effects of climate change, our influence has currently set off a modern mass extinction that may prove comparable to the Permian wipeout. Without a doubt, even if the changes stopped today, it would take nature thousands of years to undo the changes we've cause in less than 200
