Since the majority of the difference is where CO2 is only partly emissive (approx eyeball 50%), I am reducing the multiplier by half. 0.9w/m^2, add the solar forcing gives about 1.1w/m^2
dt = ldf
dt = 0.8 *1.1 = 0.88C
Compairing that to last years yearly observed anomaly of 0.51 (11th warmest) tells me that the climate sensitivity variable is too high I'll err high and set it to 0.6.
So now using all of these tweaked values and figuring we might hit 600ppm CO2 before leveling off.
CO2 -> 2.45 * ln(600/270) = 1.86w/m^2
assuming the sun stays pretty close = 2.06w/m^2
dt = 0.6 * 2.06 = 1.24C Thats assuming all of my math is at least close to realistic.
If anyone sees a problem let me know.
