I thought I demonstrated that everyone in the world at this point has to plant 1388 trees this year, to be even with emissions. It would have to be even more to lower the CO2 level. If emissions went down evenly with population, especially of high emitting countries, then we would still have to plant those 4 trees a day. Another thing demonstrated is that there just is not enough livable room for all those trees.
We can sequester CO2, as much as affordable, through a variety of means, but the key is afford.
Another thing with mitigating HGHGs is that the necessary much lower population. Lowering population by voluntary one child or less families is a logistical and educational nightmare, and certainly not acceptable to at least half the people. Besides, the math is that that is too late and not enough to lower population significantly in the time available to stop thermageddon.
A nuclear war is possible, but could easily long term poison the surface, precluding extinction of many life forms from radiation. One danger is not enough effect, and the other is too much effect. When and if it happened, how much of a nuclear winter? Would it be long enough to account for momentum of heating effect?
Population could also be lowered by geologic disasters that are due, again, if in time to account for momentum.
How about if everyone went green and lowered their footprints to 1/20th? We did it, and solar is increasing rapidly,
but again, not enough and people seem to not be going all green with recycling and lowered births, either.

From the runaway and fourth tipping point threads, if we are indeed already in an unstoppable runaway global warming from the Arctic being over the temperature of geologic past thermal maximum events, and open ocean warming can not be stopped before tundra methane self-release, then it is already too late to even mitigate what we started with fossil fuel use, overpopulation, and general inability to see the consequences of our actions in, say, seven generations.

I guess if we die trying to promote real green, maybe we will be treated kindly by our maker. I believe it is possible for Divine Interference.
