I discussed 'solar radiation management' with Steve several times including 'debating' him publicly.
I believe we were unable to detect any substantive differences in our perspectives. (We never discussed the pros and cons of specific technologies or specific conditions that might warrant deployment.) It is all about risk management. Intervening in the climate system makes sense if and only if you have fairly high confidence that doing so will reduce risk. As we do more research, the set of circumstances for which we have this confidence will evolve. John Nissen apparently thinks we know enough to be confident that we can reduce risk right now. Our friends at ETC apparently think we know enough to be confident that such approaches can never reduce risk. I think that our knowledge is in it's infancy and that because there is potential for risk reduction, we need research to define the set of circumstances (and deployment modalities) for which we could be confident that risk would in fact be reduced. ______________ Sent from a limited typing keyboard Ken Caldeira +1650 704 7212 [email protected] On Jul 26, 2010, at 23:30, Nathan Currier <[email protected]> wrote: > > > Re: Stephen Schneider's finally embracing a geoengineering idea, > shortly before he died, to help save arctic ice. > >> His views on geoengineering swung widely, first against, then perhaps in >> favor and finally supporting an effort as yet unfulfilled to stop sea ice >> melting in the Arctic by use of some kind of plastic or nylon mesh..... > > Alvia, do you (or does anyone else) know of any links to further > description of this mesh idea?
