Slow reductions=LESS CDR
I often see the argument that the more emissions remain the more CDR is needed. Example below
But it's the opposite! If a lot of emissions remain it means there wasn't enough political will & capital to address them. That will & capital won't magically appear for CDR instead

Agronomic Performance of Enhanced Rock Weathering in a Tropical Smallholder System: A Maize Trial in Kenya – CDRXIV Enhanced Rock Weathering (ERW) is a promising negative emission technology that can simultaneously sequester atmospheric CO₂ and improve agricultural productivity. While its efficacy has been demonstr...

Carbon Capture Startup Moves Project to Canada From US The startup building it moved the project north due to better incentives and what it views as a more stable regulatory environment.

Scoop: CarbonCapture Inc. has moved its 2,000-ton direct air capture project from the US to Canada, compelled by shifting political winds and a better policy environment in the north, CEO Adrian Corless told me:

Challenges and opportunities in scaling enhanced weathering for carbon dioxide removal - Nature Reviews Earth & Environment Commercial investment in enhanced rock weathering for carbon dioxide removal on agricultural lands is growing rapidly. This Review explores the potential of large-scale deployment, outlining the challenges faced in science, policy and governance to scale the technology.

Like all other CO₂ removal (CDR) techniques, significantly more research is needed over the next few decades to determine whether enhanced rock weathering is a viable method for CDR.

YouTube video by eCornell Geoengineering: The Science and Myths of Climate Intervention

Today we joined Natalie Mahowald, Lead Author of the IPCC 1.5SRE, to have a wide-ranging discussion on the topic of geoengineering, from the science to the governance challenges and ethical implications. Thanks to @cornelluniversity.bsky.social for organizing!

Out as preprint, we have some very interesting results looking at the radiative forcing impacts of the 2022 Hunga eruption. Based on the outcomes of the related OMIP, with many models from all over the world participating in this effort, we find a robust cooling signal from the Hunga volcanic plume.

Remember the #EUETS review?

Results - overwhelming majority wants the ETS installations to have access to permanent removals.
