Important paper out concluding that SRM would need to be deployed in excess of 100 years to stabilize temp increases at 1.5 C.

[H simmens]

“We generate a large dataset of 355 emission scenarios in which SRM is deployed to keep warming levels at 1.5 ∘C global mean temperature. Probabilistic climate projections from this ensemble result in a large range of plausible future warming and cooling rates that lead to various SRM deployment timescales. In all pathways consistent with extrapolated current ambition, SRM deployment would exceed 100 years even under the most optimistic assumptions regarding climate response.“

Thanks for sharing, Herb!  I haven't read the paper, but from a skim, it looks like maybe some sanity is emerging among climate modelers on this issue. Enough with "shaving the peak", it seems to me that we're going to need cooling (including probably OTEC type generating energy from and cooling ocean heat) for a very long time, even with robust GHG emissions and drawdown, and nature regeneration programs!
