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.
Cheers, John
