1️⃣ It's hard for people to visualize removing tons or billions of tons of CO₂. What if we talked about CO₂ removal (CDR) like a time machine (e.g., this machine will take us back 5 minutes*)?

*ignoring the hysteresis in the relationship between CO₂ and climate change impacts.

“The way to make carbon dioxide removal (CDR) successful is to insist on the right framing for its role. It is not a substitution for decarbonization. It’s a separate process, occurring mostly after decarbonization is complete, for legacy and residual emissions.”

Ocean alkalinity enhancement (OAE) is a promising CO₂ removal (CDR) strategy, but monitoring, reporting, and verification (MRV) involves running computationally expensive climate models. We propose a statistical technique to simplify the MRV problem.

We spent 4 years working on this paper about the scientific, legal, economic, and governance considerations of whether coastal and marine carbon dioxide removal (mCDR) can help close the emissions gap. Please take a look and tell me if it was worth it.
