If we embark
on a path that is equivalent to setting emissions to zero now (say by having a period of negative emissions in the 2035 to 2050 time frame), and call the
sequestration we accomplish mitigation then mitigation can arrest climate change, make adaptation unneeded and bring us to a safe concentration of
carbon dioxide in the atmosphere as Hansen has pointed out.
But it's too simplistic to rely
