"What could possibly go wrong" is that by continuing to not take CDR and SRM
seriously (Mann and Toles), we will increasingly commit ourselves to drastic
emissions reduction - "the simplest safest solution...to address the problem at
its root cause" - last line in the chapter. Everyone is for simple and safe,
yet how simple has emissions reduction proven to be and how safe is it to
assume that our dismal emissions track record will magically change? Even the
ultimate keepers of climate truth, the IPCC, now tell us that simple and safe
alone isn't going to keep us below 2 deg C warming and that BECCS and
afforestation will also be required. While this too may prove to be magical
thinking, how wise is it to denigrate what needs to be a serious effort to see
if we have any additional options for staving off global warming and ocean
acidification?
Mann and Toles have each in their own way contributed significantly to the
climate change issue, but when it comes to solutions they do a disservice to
the cause by broadly painting alternatives to emissions reduction as mad-cap
science fiction (curiously, except for DAC?!?). What are their better ideas in
the now likely event that emission reduction attempts fail to singlehandedly
solve the problem, and do these ideas themselves pass the laugh test?
