My question to them would be: Why wouldn't normal H2O evaporation and the heating from that cause runaway H2O evaporation and ever increased heating. It is not like there is a shortage of H20 available in liquid form.
The truth is not convenient for those who want to be in control of the means of production.
For the same reason they think "heat" from global warming can sink below cold and hide in the deep ocean
or
or how they believe the record sea ice in Antarctica is caused by global warming melting glaciers which causes the salinity of the ocean to drop thus lowering its freezing point, but then can't explain how come the same thing isn't happening in the Arctic (We are always hearing about how Greenland & Alaska Glaciers are melting arent we? So shouldnt there be record sea ice around them and the Arctic as a whole?).
That is too say, they just make up what ever physics their hypothesis to work
The equation for photosynthesis is 6H2O + 6CO2 -> C6H12O6 + 6O2
AND IT IS GREEN...................................
