There's an established link between SRM and CDR, via increasing ocean acidification by dissolution.
MCB would seem to be more directly effective than SRM, as nearly 100pc of its effects go into cooling the ocean surface and lower Tropospheric air over the ocean. Has anyone modelled this? If not, can someone please put it on their "to do' list? A On 5 Jul 2017 06:22, "Ronal W. Larson" <rongretlar...@comcast.net> wrote: > Greg, cc list: > > 1.
