David Appell— IMO, the best evidence is the measurement of an increasing greenhouse effect:
JK—————-How does that implicate man’s CO2 emission? Where is the connection between CO2 and radiation balance? Especially since water vapor causes much more “greenhouse” effect than CO2. And since clouds have been shown to be created as a result of galactic & solar effects.
And if you argue that it is only CO2 causing the radiation unbalance, where is the proof that it is man’s CO2 and not nature’s CO2 (which is 95% of the CO2 emission).
If you drag up that old tired carbon 14 argument, then explain how we know that man’s CO2 is the ONLY conceivable source of “old” carbon.
So, David, as I have been asking you for several years, where is the real proof that man’s CO2 is causing dangerous global warming.
Thanks
