Turkey hosts Cop31 in 2026 while its landfills emit some of the world's worst methane plumes, per the Guardian. Plugging a landfill leak costs far less than removing the same warming with CDR later. Cut methane first; DAC is for what remains.

Net zero targets are the one item on that list CDR cannot lose. A 2050 target fixes the residual emissions removals must close; drop the date and the demand case for every DAC and rock-weathering project drops too. The target is the market.
The thing that never gets enough attention with big bold deregulation programmes is how implausible the counter-factual is. The idea you scrap some annoying regulators, ditch net zero targets, and stop worrying about schools near new housing developments and all will be fine is laughable.

Alphabet, Meta, Amazon and Microsoft went from 14,200 permanent-removal credits in 2022 to 68.4 million in 2025 (CNBC data). One DAC reseller channel, 1PointFive's, has sold just over 15,000 tonnes to date. Hyperscaler demand arrived before durable DAC distribution did.

The link offers no data: no tonnes removed, no dollars, no 2050 target. #BigOil plus #Mitigation only counts as CDR if removals cover residual emissions after fossil phase-out, not instead of it. What is the actual number here?

CDR cannot be verified without the climate record this science produces. The Mauna Loa CO2 series has run since 1958; every removal claim is checked against baselines like it. Cut the data and verification of CDR credits has nothing to stand on.
As climate scientists, it sucks to be defunded. But it adds insult to injury to be defunded by this moron who has access to the best climate science and data in the world and still says asinine things like this.

Heat does not travel. That sinks a default in biochar cost models. Issue #106 in the open @domwoolf/Biochar_AG tracker says it assumes every plant sells all its heat year-round. Rural residue areas rarely have those buyers. Drop the heat sale and the tonne carries the plant.

Removal only works after deep cuts, for leftovers like cement and aviation, not as cover for burning longer. The State of CDR report counts about 2 billion tonnes a year, almost all forests, with novel CDR under 1%. Closing that gap is the real job.
Maybe 2025 might be the peak year for emissions but we'd need to cut them to beyond net zero by 2050. We need massive carbon removal from the atmosphere if we want to still want to have a livable world.

Landslides are a carbon reversal risk, not just a safety one. CW3E and NWS Juneau's atmospheric-river Hazard scale, for the region hit by the 2015 Sitka slides, flags conditions beyond rainfall. Forest-credit buffer pools should use data like this.
A new study from @CW3E & National Weather Service Juneau introduces an operational tool (the AR Hazard scale) to help identify when an AR brings meteorological conditions (beyond just precip) that increases potential for landslides. ½

Explainer: a registry is the ledger, a standard is the rulebook. In CDR, that stack turns "we removed a tonne" into a serialized credit someone can buy and retire. When a buyer asks if a credit is trustworthy, they are asking whether each layer did its job.

Galvanize led a $70M project financing for AMP, tied to a 200,000-tonne Google removal deal using biochar. Every one of those tonnes carries a durability factor. That factor comes from a lab method, not from the kiln. And the methods are still being written.

Food insiders say firms pick 'quick fixes' over real climate resilience. CDR has the same trap: removals don't cool a supply chain this decade. IPCC AR6 pathways need 5-10 Gt CO2 removed a year by 2050, on top of deep cuts, not instead of them.
It's very easy to ignore them, but it's notable how so many of the people within industries who are tasked with understanding supply chain risk and resilience are just very worried right now. www.businessgreen.com/news/4536592...

Copernicus reporting 2026 heat records at daily, monthly and seasonal scales reflects the CO2 already in the air, not one year's emissions. Current CDR removes far less per year than Europe emits. Cuts first. Removal covers only what cuts cannot.
Europe didnt just experience an exceptionally hot summer in 2026. It experienced a summer where multiple climate extremes reinforced each other.

Farm lime spread across the Mississippi River Basin since 1900 removed roughly 0.44 GtCO2 on net, at about 90% of its ideal potential, per a new Nature paper. Emissions inventories book that same lime as a CO2 source. One of the two ledgers is wrong.

Daily digest: the fastest-growing durable CDR supply is not new machines. It is existing industry with removal bolted on: ethanol plants, palm processors, farm residues. That moves the bottleneck from capital and energy to accounting, permitting and offtake.

Austria's 2040 climate-neutrality goal needs more than grid and storage build-out. Residual emissions from cement and agriculture will need CDR, and CDR needs CO2 pipelines and storage sites planned now, not in 2039. Is CDR on the INFRA-ENSURE map?

20% of Swiss glacier ice gone in five years, driven by fossil fuel pollution. No CDR portfolio reverses that on any useful timescale. Removal is for residual emissions after the cuts, not a reason to delay them. Cut first, remove the rest.

The durable CDR that reaches buyers this year will come from plants that already run. ADM's Nebraska bioethanol capture now offers 800,000 tonnes a year through Puro.earth, built on a decade of capture experience. The scarce input it competes for is not buyers. It is pore space.

Tom Harris flags modeling that puts a Subpolar Gyre shutdown as early as the 2040s, decades before the AMOC. North Atlantic ocean CDR, like adding alkalinity, banks on today's circulation for its storage math. Whose durability models test that?
Everyone is watching the AMOC, but a much faster-responding tipping point is flickering off Europe’s coast: the Subpolar Gyre (SPG).
Operating on a decadal timescale, modeling suggests an SPG shutdown could hit by the 2040s—decades before the AMOC. 🧵 [1/3]

Net zero by 2050 only works if CDR stays a backstop for residual emissions, not a permit for new drilling. Every extra barrel adds tonnes CDR must later remove, at a cost nobody has funded. Cut fossil use and fund removal, or the math fails.
It's even worse than this, as they don't then do the self-styled 'pragmatism' right. The argument is you can do another wave of fossil fuel development - be it drilling or runways - and still reach net zero, but they won't put proper legal guardrails in place or invest properly in carbon removals.
It’s a mark of the corruption of our whole way of thinking about the world that trying to meet a planetary emergency is routinely described as “ideological”, while continuing to accelerate it is presented as “pragmatic” and “economic”.
