Ultimately it would take centuries to bring the atmospheric CO2 to a new equilibrium value. (realclimate.org)
I'm not sure, but I would imagine that it would cost a great deal to support a large asset class above its theoretical equilibrium value. (alephblog.com)
After that, emissions taper to zero — they must — CO2 concentrations go asymptotically to what corresponds to about half the total ever emitted — the other half going into the ocean and biosphere — and temps go asymptotically to the long - term equilibrium value for that concentration.
