This new tool, the Carbon Impacts Tracer, which translates carbon emissions into real-world climate impacts like heat exposure and coral bleaching, looks super useful. ➡️ carbonimpactstracer.com

New tool directly links carbon emissions to amount of environmental and economic damage caused
Carbon Impacts Tracer can be used to estimate climate impact from emissions across eight different factors, including lost food production

There’s a lot of pessimism about mCDR, its role, whether it can ever be deployed at scale. I ask myself the same questions daily. But here’s our technical team 💥 putting our mesocosms in the water at 6am for the next OAE experiment. Only KOSMOS-GEOMAR has tools like these anywhere in the world
Pre-dawn dockside scene: three KOSMOS mesocosms — large transparent domed floating enclosures wrapped in protective covers — lined up on a quay, ready for deployment.

I think the way to read the UNEP report isn't "we'll miss the 1.5°C target so we need CDR to reach it", but "we'll miss the 1.5°C target, and we need to decarbonize ASAP because wherever we end up is where we will stay for a long time." www.unep.org/resources/li...

🧵CO₂ removal (CDR) is back in the news, but just because the UNEP report says we need CDR, it doesn't mean we'll have CDR. Many challenges will take decades of research and negotiation to solve. Here are some examples: Technological: We currently don't have any durable CDR method that scales.

Book #25 of 2026. Away for a while, so I had to bring my Kobo, and I usually struggle to read on it 😬 So I picked Liz Moore, a writer worth the hype. The “The Unseen World” is an incredible book. You can’t stop reading it Now I’ll miss Ada, David, Liston and all the rest. Highly recommended 📚💙

I have some thoughts: Marine CO₂ removal (mCDR) research and development should be carried out by governments, not by startups funded by VCs and philanthropy. These startups will either go belly up soon or sell themselves to a fossil fuel company for greenwashing. carbon-pulse.com/530652
But not all are convinced that private companies are the best route to scaling mCDR. David Ho, a professor of oceanography at the University of Hawaii at Manoa, was part of early mCDR research efforts both within and beyond academia. Ho is an established researcher in ocean science key to the veracity of the field, but he also co-founded a non-profit organisation in 2023 to build software that supports mCDR research.
Ho thinks that the field should be a government-funded or government-run research effort, not driven by companies via venture capital and private funding.
"There's so much that we need to figure out that companies are not going to do. They are there to work on their [own, specific] technology," he said.
Ho pointed to areas of research essential to scaling mCDR - in the realms of environment, geophysics, governance, and social studies - that companies are not necessarily prioritising.
"They're not thinking about that. It's 'How do you develop intellectual property that you can maybe sell to a fossil fuel company?' I bet every single one of them looks at the exit that Carbon Engineering took and says 'Well, we too would like to get $1 bln.' And that's the best exit for any of them right now, because they will never be paid billions of dollars to remove carbon."
