Folks,
This Sunday evening, I am supposed to help kick off a discussion about what
we know and what we don't know about solar geoengineering.
https://www.grc.org/programs.aspx?id=17348
It would be helpful if some people on this group could attempt to answer
these questions:
*1. What are the mos
* What are the unintended side effects for different methods under
consideration
* Benefit – risk analysis over time

Hello Ken,
my two pence, not repeating Klaus' input.
/1. What are the most important things we know about solar
geoengineering?/
some techniques can cool the planet, rapidly and in a reversible way
(although the impacts may not all be reversible)
there are side effects, eg on precipitation pat
Only thing I'd add to Klaus's nice summary is this:
We don't know of a model for decision-making on a global intervention on
any other issue yet that can apply neatly to this kind of action.
- CFC/ozone diplomacy was about mitigating something, not adding something.
- Nuclear test ban same.
So
methods under
consideration
- Benefit – risk analysis over time

What are the most important things we know about solar geo-engineering?
* It can be done, it is comparatively cheap, but probably not as cheap as
people
