Hi Greg, I am a defender. But there is a lot of resistance to presenting the case for geoengineering. For example, Gavin Schmidt gave a talk on advocacy at AGU and I asked him whether he'd allow me to be an advocate for geoengineering on his blog, Real Climate. He refused. In public! I was gobsmacked.
Obviously, the case for geoengineering involves making a case for the requirement for geoengineering. My group has made a case for CDR, combined with stringent emissions reductions, to bring CO2 down to 350 ppm *within two or three decades*, as required to reduce serious risks from ocean acidification as well as global warming. We argue even more strongly for SRM specifically to cool the Arctic, before it becomes seasonally free of sea ice and gets locked into a rapid warming mode with even worse consequences. I have a full text of our submission to COP-21 which I can post here if anyone is interested.
