I agree with anonymous that it is absurd to reason that there is only positive feedbacks associated with anthropogenic CO2 and alleged resulting evaporation.
There is an inconsistency in Kyoto dogma.
In the Kyoto text, it states that water vapor results from a natural process, and besides it is too difficult to model. The bulk of CO2 is also produced from natural processes.
In the US/Boundary Waters Treaty and water apportionment agreement between the three Canadian prairie provinces, evaporation losses from reservoirs are considered anthropogenic and charged as a water use to the upstream jurisdiction. From regional evaporation charts, for the reservoirs in Canada I estimate annual water vapor loading of 2,600 megatonnes which does not include the probably considerable greater loading from evapotranspiration associted with irrigation. The anthropogenic CO2 loading currently attributed to Canada is about 950 megatonnes for a relatively minor greenhouse gas as compared to water vapor.
