I am a little more optimistic.
Sooner or later we will have to develop a degree of active climate
control, (nature can not be trusted forever). This is the real task at
hand, not stopping global warming.
There are many more effective methods of directly controlling global
temperature than by atmospheric CO2, (search google), also, we should
only be treating the detrimental symptoms. Increased atmospheric CO2 is
otherwise highly beneficial for global biomass and biodiversity. One of
the things that causes ice ages is the natural accumulation of fossil
fuels, (reduction in atmospheric CO2), which an ice age stops, until the
slow rate of natural CO2 release eventually restores the balance.
One of the best ways of controlling sea level is to slow wind and ocean
currents and ice flows in and out of the polar regions. This results in
the accumulation of ice at the poles, this also results in increased
reflection of sunlight back out into space, and a reduction in global
temperature.
Dam the ice flows, one method might be to use long 1000 ton spectra
ropes, as used for pulling ships, with ice harpoons at each end. Drop
them from helicopters to prevent ice flows from breaking up and floating
away to warmer climates, this could be quite cost effective.
Power generation from ocean currents is almost economic now, (wind power
is), increasing the scale of such by a couple of orders of magnitude
basically gives us the capacity to partially influence wind and ocean
currents, and also solves our energy problems. With such a system we
could directly control sea level, and even influence temperature and
precipitation at a regional level, assuring the likes of the gulf
stream. This could be economically sustainable, especially if one could
economically incorporate the climate control benefits. The agricultural
and catastrophe prevention benefits alone could be in the trillions of
dollars.
