If I randomly assume a 1% increase per year in each factor will cause a

that prevents such uncontrolled increases. So far, the various
mechanisms for absorbing CO2 (vegetation and ocean absorption) have
been demonstrated to be inadequate. What keeps CO2 and temperature
from increasing each other without limits?

**No idea. And THAT is precisely the problem. Both may end up increasing
until CO2 levels and temperatures are so high that several catastrophic
phenomena occur. CO2 levels could reach (say) 5% or so. Return to 'normal'
levels would likely take several million years.


The explaining power of the model is worthless then.
