This blog distills the article’s key insights, in which the 42 experts in polar and climate sciences, policy, and governance evaluate SAI (among others) using six criteria:
1️⃣ Feasibility
2️⃣ Unintended consequences
3️⃣ Scaling
4️⃣ Timing
5️⃣ Governance
6️⃣ False hope

A blog by Dr. Marie Cavitte, written on behalf of the 42 authors of “Safeguarding the polar regions from dangerous geoengineering”, an article that has rightly been making waves across both science and media since its publication in Frontiers in Science.
