  •  And that would produce little effect. (1+ / 0-)

    As we've already passed the point of no return. We either need to develop technology to reflection sunlight away from earth, or technology to capture carbon from the air. That's it. We're reduced to a magic bullet or Venus.

    •  That is not true (0+ / 0-)

      it must not be true.  

      because the idea of reflecting sunlight with geoengineering is a self-defeating game.  We will have to halt CO2 emissions if we want to prevent a +8C scenario.

      •  Must not be true? (0+ / 0-)

        Well enjoy your convictions.

        But since every piece of data we get shows this is happening worse than we thought and at a faster pace, I think we've run out of options.

        •  no, it only means (0+ / 0-)

          that we have to work harder and faster, not that it is too late.  Now, when we get to 450 it will be far too late.  The only uncertainty right now is whether or not we can mitigate the levels to slow the thaw of the permafrost, and if there is a reasonable reforesting project that can increase CO2 removal.  A 10 year u.s. decarbonization strategy with a 20 year global decarbonization focus and a 100+ year biosphere recapture program will do it.  Otherwise I fear we will have a precipitous population collapse in 40 years.
