It is one of the main power sources they hoped for, and this shows it's size is bounded above. The article does not, however, provide any of the numbers - a distinct drawback. Somehow if the result were 95% of what is needed to maintain relative humidity - i.e. keep a large positive feedback - I think they'd have mentioned it. More likely, the available power is an order of magnitude smaller than direct greenhouse effect. The 5C scare predictions have no power budget and every time they try to allege one, it falls apart.

It may be that the level of confirmation of the model in the upper troposphere data doesn't allow (at present) the quantification that you mention here. Still, this is just getting out -- we may see estimates like that soon.
