Hourglass Climate's Dr. Grace Andrews and Kristi Weighman on the launch of the Framework for Ecotoxicological Modeling of mCDR

About this episode

The episode features a discussion on the launch of the Framework for Ecotoxicological Modeling of mCDR with experts from Hourglass Climate.

In this episode, hosts Anna Madlener and Wil Burns are joined by Dr. Grace Andrews and Kristi Weighman of Hourglass Climate — a leading nonprofit researching ocean-based carbon dioxide removal (oCDR, also known as mCDR ) methods like ocean alkalinity enhancement (OAE) — to discuss the launch of the Framework for Ecotoxicological Modeling of mCDR (FEMM). This project explores how ecotoxicological modeling and existing statistical approaches can be applied to OAE and oCDR projects, improving th...
