Sounds lovely, however our greenhouse gas reality is well explained here and neatly summed up:
Promote sustainability or continue shoving your head in the sand with a vengeance. It's always tempting to just say "To each their own" or "Can't we all just get along?" but the choice is clearly a deeply moral one in this case.
This doesn't change anything I said about the POWER of CO2 to warm the surface DECREASING LOGARITHMICALLY with atmos concentration. Man's contribution to the yearly SOURCING of CO2 cycle in 5%, nature's is 95%..
Circa 2005, the estimate was that the natural carbon sinks were absorbing 1/2 of man's contribution. Which about jives with rate of rise of atmos conc.
But here's the fuzzy part. 2.5% is probably SMALLER than our uncertainties on ESTIMATING land and ocean sink rates. OR the limits of their capacities. And for certain, declining sea ice for example -- OPENS UP MASSIVE ocean CO2 sinking capabilites greater than planting trees in all that un-iced area.
We could be LOSING land CO2 sinking for a variety of human effects other than CO2. Unless you REFINE our educated guesses on the NATURAL sources and sinks and how THEY are changing -- you might just get lazy and attribute it ALL SOLELY to man's 5% of the annual CO2 cycle.
