Seems the data supports that nature already has failed to prevent CO2 increases from man's activity. The data suggests CO2 levels would be much higher without these natural sinks, they must be working overtime. Isotope data clearly marks CO2 produced by humans. Temperature is hardly the only data to support this and in some ways appears to be the weakest data.

380 ppm to 500 ppm seems significant. When will natures ability to handle extra CO2 stop?
Skeptics say that C02 is already absorbing "*almost all it can*" and additional increments "*won't make much difference*".
Page 8 of *The Skeptics Handbook* makes this claim:

If the skeptics are correct on this point, then it would seem that nature has a *long* way to go even if we assume no further absorption by other natural CO2 sinks.
