You know... the thing that boggles my mind, is that they know the entire atmosphere of GHG's is only 44% effective at trapping its theoretical SURFACE temperature because convective currents whisk the heat into the upper atmosphere. They know that. It's not some unknown thing. It's common knowledge. So how can they not bat an eye at a model which predicts the GHG effect of an incremental 280 ppm of CO2 combined with its associated feedback (i.e. water vapor) is 450% effective at trapping its theoretical SURFACE temperature.What laboratory experiment can we perform that demonstrates this? ... why can't CO2 be just a good GHG as any other ... water's 20 times as powerful because there's 20 times as much mass ... and we can statistically jack that up to 50 by using molar mass values ... one photon, one molecule ... how it is in the universe ...
Riddle me that, Batman?
