The Way We Talk About Geoengineering Matters

Solar geoengineering describes a set of approaches that would reflect sunlight to cool the planet. The most prevalent of these approaches entails mimicking volcanic eruptions by releasing aerosols (tiny particles) into the upper atmosphere to reduce global temperatures – a method that comes with immense uncertainty and risk. We don’t yet know how it will affect regional weather patterns, and in turn its geopolitical consequences. One way we can attempt to understand potential outcomes are through models.

Confronting Solar Geoengineering: What You Need to Know

Climate change threatens public health, food security, water availability, and national security – just to name a few areas of impact. Dramatic reductions in emissions and increased investments in measures to adapt to unavoidable impacts are essential but may not be enough to limit severe climate risks—and to date, these actions have fallen far short of what is needed. Some researchers are proposing to do experiments to also test the potential feasibility and effectiveness of geoengineering approaches to help limit climate change, while recognizing that mitigation and adaptation must remain our first-line solutions.
