Yesterday, Edition 3 of the State of Carbon Dioxide Removal Report was released. 🚨✅ Chapter 10, led by Sabine Fuss and Abby Lunstrum, provides update of estimated mitigation potentials and costs for various #CDR methods. 🔍🔦 (Brief overview below)

This is great work. The carbon math is that we have to get emissions to net zero quickly & we need CDR AS WELL, and we need nature based solutions. Let’s do those. But folks have used the possibility of nature based solutions as cheat code to delay doing the harder stuff. The thing is, it is not.

In our latest paper with @manonberger.bsky.social, Lester Kwiatkowski, and @bopplaurent.bsky.social, we show that if we properly account for iron limitation and nutrient competition with phytoplankton, growing seaweed isn't really an effective technique for removing atmospheric CO₂. 🌊🧪

Hi everyone, in the course of NorESM development for CMIP7 - we've had need to do some rapid benchmarking and diagnostics. To this end, I've made a couple of tools which might be useful for the wider community - python ports of ncview and CMAT. /thread/

One frequently sees headlines that X is warming faster than the global average. That's true of nearly everywhere that humans live, but only because humans nearly all live on land. The process of global warming will generally warm land faster than the oceans.
