Apologies. I (and so you) meant C14/C12 ratios. I gather that you
accept that the excess carbon in the active carbon cycle is of fossil
origin, placed there by humans burning fossil fuels. I gather that
you accept that additional CO2 in the atmosphere (all else being
equal) will warm the planet. Then why do you not accept AGW?
Once the physics of global warming gases is understood (at least 100
years now) and once the source of the excess carbon is understood to
be anthropogenic, it seems to me that scientific methods directly
arrive at the conclusion of AGW.
