T_offset = 0, T_ground = 298.52 K, Upward heat flux = 298.52

T_offset = 2, T_ground = 301.7 K, Upward heat flux = 307.44
W/mĀ

Conditions are CO2 = 400 ppm, Tropical region, No clouds

Clouds hold the heat in, but reflect more solar energy.

The model also shows that DOUBLING the CO2 concentration to 800
ppm has a minimal effect on outgoing heat:

T_offset = 0, T_ground = 299.7 K, CO2 = 800 pp,, Upward heat
flux

= 295.2 W/mĀ²

To get the UHF back to 298.5 W/mĀ², increase T_offset to 0.75
K. So doubling the CO2 level increases the ground temperature
by 2 K. That doesn't look like a "tipping point."


Don'tcha just love oversimplification for effect?
Is Big Carbon's pocket money allowance taxable?

If stupidity had a tangible value, people named "Chris" would all
be rich.
