What about the perturbation of the typical cycles by dumping lots of climate warming gasses into the atmosphere?

If nothing serious is done (as we are doing at present) and the warming becomes a runaway, it will progress until the causes have dissipated (e.g. we are no longer pumping GHG into the atmosphere and the natural sources of these have been exhausted or at least come into some kind of equilibrium.)

I'm too old to be able to witness that but I think our race as a whole is likely to do so.
