Dear Alan
Can you tell me which of your 26 objections apply to marine cloud
brightening?
I am sure that many of the people who want research on but not
deployment of geoengineering systems are greatly reassured that you are
there to spot the nasty problems. Keep up your valuable work.
I too was at the Ames meeting and confirm your recollection.

Dear All,
I also was at the NASA Ames meeting. It was my first geoengineering
meeting, and it was there that I was struck with the very enthusiastic
endorsement of geoengineering as a solution to global warming by
people who did not seem to be aware of the potential negative impacts.
But Lane and Kheshgi were not among those who were blindly advocating
geoengineering, as I remember it. I agree with Clive that the reason
we are even considering this Plan B is that Exxon and other fossil
fuel companies have had a dedicated campaign to deny anthropogenic
global warming, and that AEI has been part of this campaign, and that
if they were to now advocate mitigation we would not be nearly as
interested in geoengineering. But it was not such a black and white
discussion at the Ames meeting – it was more of a general discussion
of geoengineering and a learning opportunity for many.
It was at the Ames meeting that I wrote down my 20 reasons why
geoengineering may be a bad idea, as I listened to two days of
presentations. (My research program since then has been to investigate
those reasons. I have now crossed out three of them, but added nine
new ones, so the total is now 26.)
