Take on a podcast episode from Carbon Removal Newsroom, originally published Tue, 14 Ju. Listen: https://climateworkersanonymous.substack.com/p/4-the-denial-of-grief-plays-a-central

TL;DR

  • An anonymous submission argues for pausing all crediting of enhanced rock weathering (ERW) and ocean alkalinity enhancement (OAE) until end-to-end verification improves. Critical but fair.
  • Core mechanism: open-system removals can’t be directly measured, so “phantom credits” used to offset real emissions pose both climate and reputational risk.
  • Claims early findings already show actual removal well below estimates — no citations given, but directionally consistent with recent field-trial literature.
  • Host Ross Kenyon explicitly frames all submissions as unverified. Treat this as practitioner-sentiment data, not evidence.
  • The CDR-relevant content is roughly five minutes; the other two submissions (climate grief, virtue signaling) are off this beat.

Episode #4 of Climate Workers Anonymous is Ross Kenyon’s anonymous-submission project: climate workers send in things they won’t say under their own name, and he reads them aloud. This episode carries three submissions, and one of them is a direct shot at the crediting of open-system carbon removal — which is why it’s worth flagging here despite the show’s soft format.

The submission is a pause argument, and it’s structured better than most: (1) open-system pathways like ERW and OAE can’t have their carbon storage directly verified; (2) findings are “already emerging demonstrating that actual removal was far less than previously thought”; (3) therefore crediting against positive emissions risks phantom offsets that “gravely harm the reputation and ultimate scalability of the industry.” The proposed remedy is research-first: no formal crediting until end-to-end process understanding improves. What’s notable isn’t the argument’s novelty — the measurement-vs-modeling debate has run through every ERW protocol discussion since 2023 — but where it’s appearing. Someone inside the industry apparently holds this view firmly enough to publish it only anonymously. That’s a data point about how contested open-system MRV (measurement, reporting, and verification) still is among practitioners, not just among academic critics.

The obvious counterargument, which the submission doesn’t engage: crediting is currently the main funding mechanism for exactly the field data the submitter wants. Registries have mostly responded to measurement uncertainty with conservatism — discount factors, model-plus-measurement hybrid approaches, near-field monitoring requirements — rather than pauses. Whether conservatism is sufficient when the underlying signal (cation transport to ocean storage, secondary mineral formation, air-sea gas exchange for OAE) plays out over years and kilometers is the live question. The submission’s “far less than previously thought” claim tracks with published field trials showing weathering products getting stuck in soil exchange sites rather than reaching durable storage, though the submitter names no studies and Kenyon, by design, verifies nothing.

Worth situating: Kenyon spends the episode’s opening laying out the project’s limits — he’ll generalize submissions that name specific parties and redirects whistleblower-grade material to investigative journalists. So don’t expect this venue to surface which projects, if any, the submitter has in mind. The written versions of all submissions live on the project’s Substack. The other two submissions — one on grief denial as the engine of climate work, one asking colleagues to virtue-signal less — are humane but outside the durable-CDR conversation.

Useful for buyers, registry staff, and open-system developers tracking how MRV skepticism is circulating inside the industry itself. Skip if you want data rather than sentiment — the episode contains exactly one argument and zero numbers.
