CO2: RF = 5.35 ln(CO2/CO2_orig)
This will be above a few heads, but it is a point sorely needed to be understood. Look at the ratio of how warming will take place from co2 alone. It is a ratio of todays co2 to the co2 of the 1800's. As todays and tomorrow's co2 increases so does the downward radiation of infrared energy.
This means more warming of the earth at the surface.
There is no politics to this warming. But unfortunately there is politics in the perception of global warming. That is where we are all getting hurt by this.
