Funny that they say 1.6W/M2 since the 1750 for CO2 forcing.. I was quoting 3.6W/M2.. I need to check that reference. The TSI chart shows 1.1W/M2 since about 1750.. Doesn't leave much room for MASSIVE Co2 warming does it??
Go back to the IPCC radiative forcings bar graph and add up all the human contributions. You'll get 3.2 W/m*2. And that includes NO positive feedbacks.
Actually the 1.6W/m2 agrees with IPCC CO2 forcing in that chart.. I'll be darned.. I thought it was 3.x something.. As derived from CO2 log forcing function on concentrations from 1800... ??????
Human contributions are not 3.2W/m2 -- Net human contributions show as also about 1.6W/m2 in that figure.. Maybe all the POSITIVE forcings add to 3.x, but that's not the pertinent figure I was doubting..
Imagine that --- a shiny data gem for the day..
