Err thats because your Athmospheric preasure has increased.
Not really. The atmospheric pressure only added .01 GH factor. The greenhouse gas added the .1. Thus the 1.11 GH Factor.
And i think i misworded my previous post it could have been GHP instead of GHF.
Doesn't matter. GHP increased by .1 anyway.
As far as I can tell, adding .1 ATMs Carbon Dioxide or SGG had the same effect on Pluto as on Mercury. 1.11 GH Factor, 0.1 GHP, an increase in ground temperature of 11%.
