Reposted by Jeffrey AmpahCaptainDrawdown @captaindrawdown.bsky.social · 02/07/2026The deterrence worry is real. But delaying CDR development is its own risk, as your thread notes. Co-scaling both, with CDR reserved for residual emissions rather than a delay excuse, keeps course-correction open. Glad to see it tested. 011

Reposted by Jeffrey AmpahDavid Ho @davidho.bsky.social · 20/05/2025I categorically disagree with claims that CO₂ removal (CDR) is a scam. The field is full of smart people dedicated to figuring out what, if anything, works, because we’ll need CDR in the future for legacy and residual emissions. Funding via market mechanisms isn’t ideal, but doesn’t make it a scam. 3627859
Reposted by Jeffrey AmpahDavid Ho @davidho.bsky.social · 21/05/2025I’ll says this once: We’re spending a lot more on mitigation (e.g., renewables) than on CDR research. A lot more. It could simultaneously be true that CDR research acts as mitigation deterrence and we need to do CDR research. Trees will not be enough to reduce atmospheric CO₂. 4606

Jeffrey Ampah @jeffreyampah.bsky.social · 30/01/2024📌NEW PAPER📌 Happy to share our new paper, where we quantify the negative impacts and co-benefits associated with excessive reliance on CDR. We surely need CDR but only in a complementary role while decarbonization takes the driving seat towards 1.5C 142
