Freebeard: Red is contribution to warming, blue cooling. The feedback is flat out burried. It was acknowledged years ago that the direct forcing of CO2 was small and that it was only the feedbacks such as less sea ice, more water vapor etc that brought the full contribution of CO2 out.

According to a NASA paper I read a few years ago the increase in solar output is approx 0.1%, or the same as the solar cycle. I am trying to redo my calculations.

Solar output is about 1350w/m^2

The average Albedo for earth is 0.3, which means the earth absorbs 70% of the energy from the sun.

The rato going from circle (what the sun sees) to sphere (total earth surface) is 1:4

So 1350*0.7 = 945w/m^2 (absorbed)

(945*0.001)/4 = 0.236w/m^2 increase due to just solar forcing with no feedbacks. (higher but within their error bars)

Neil: All of those effects would happen no matter the cause of global warming.

Edit to add: Neil, I support what you and others do on this site, even though I don't support the reason. There are other more immediate reasons to reduce, or move away from burning fossil fuels.
