Recently, I attended my 30th-year MIT reunion and had the chance to hear some excellent lectures from MIT professors. One of them was a hands-on workshop on En-ROADS, a climate solutions simulator developed by MIT Sloan and Climate Interactive.

This powerful tool is designed for policymakers, climate experts, advocates, and really anyone concerned about the climate crisis (which should be all of us). It lets you simulate a wide range of climate policies and interventions—such as reforestation, carbon pricing, electrification incentives, or nuclear energy development—and immediately see the projected impact through clear, dynamic visuals.
