T_offset = 0, T_ground = 298.52 K, Upward heat flux = 298.52 W/m²

T_offset = 2, T_ground = 301.7 K, Upward heat flux = 307.44 W/m²

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/m²

To get the UHF back to 298.5 W/m², 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?
