David, list, et al
Re your "...what papers...." question below, I suggest that for me the
most powerful are the many from Jim Hansen - clearly saying that even 350 ppm
is probably not enough. He has mentioned in his papers both biochar and
afforestation in the CDR area. I presume you are familiar with his position on
the need for CDR, but can give more specific citations. I seriously doubt the
NRDC is going to disagree with Hansen on the urgent need for 350 or better -
are you?
I think that the FOE position is more positive than John Nissen has
described - and will comment on that next.
I don't think it pertinent, because the subject was the Keystone
pipeline, but Hansen gave powerful testimony on the need for carbon reductions
before a Senate Foreign Affairs Subcommittee a few days ago. See
