Thanks Mark. You start off the piece saying that "optimism is necessary", but I
would think a more important necessity is solving the climate problem. As you
say, emissions scenarios from high places clearly tell us that at this late
date we will very likely fail with an emissions-reduction-only posture. So I
am unclear where the "moral hazard" is in evaluating or even discussing
additional methods (except possible hazards to the emission-reduction
lobby/stakeholders(?)).
The greatest hazard we face is antho climate change (+ ocean acidification).
If the experts tell us this is not getting solved by known methods in the time
remaining, isn't it a moral imperative rather than a moral hazard that we
actively solicit and evaluate additional methods? At the moment I think an
issue more pressing than global governance is whether or not we actually have
any cost-effective and acceptable-risk options worth governing. That question
can only be answered by R&D and testing, which can then be used to inform
whether or in what form governance is needed (and to find out if any optimism
justified). Couldn't too little, too much or the wrong kind of CE governance
also prove hazardous to reaching our climate objectives?

"Climate communicators have worked hard to create a more optimistic brand of
messaging. “We can still beat this, as long as we cut emissions more quickly,”
goes the refrain. But at what point does such optimism become
counterproductive, if its assumptions are no longer true?"--
