I'm sorry to pick out one sentence that I don't entirely agree
with, but here goes:
it is probable that at least much of the
change can be mitigated by increasing the earth's albedo, which is a
bit of geoengineering that we can do and probably can control.
The "control" part is still open to question.
I don't disagree with JD's quibble about my comment on albedo change
as a controllable bit of geoengineering. I probably should have use
the adjective "possible" instead of probable. In general, I am not a
fan of the approach to solving the problem by geoengineering. It is a
dangerous game and controlling it will probably be more difficult
that anyone realizes.
