Can Stratospheric Aerosol Injection Refreeze the Arctic?
Students examine whether stratospheric aerosol injection could cool the rapidly warming Arctic, and why a regional intervention would still affect the whole planet.

Modeling the Potential Impacts of Stratospheric Aerosol Injection: Knowns & Unknowns
Students learn how climate models simulate stratospheric aerosol injection, why models disagree, and what research is needed before its effects are understood.
-
A New Taxonomy of Climate Interventions: Card Activity
Students sort 75 climate intervention cards by where each begins in the Earth system and trace intended and unintended outcomes.
-
Research or Not? Classifying Solar Radiation Modification Experiments
Students learn to tell SRM research experiments from commercial or deployment activities, classify real cases, and debate a proposed non-use agreement.
-
Solar Climate Intervention
Students compare proposed ways to cool Earth by reflecting sunlight, then weigh their potential benefits against risks, moral hazard, and governance challenges.
-
Solar Radiation Management: How Might We Manage Climate Overshoot?
