[AGU26] Call for Abstracts - GC033 - Constraining Climate Intervention Impacts Using Observations Following Natural Analogs and Laboratory Experiments
Lili Xia
We invite you to submit an abstract to our AGU 2026 session: GC033 - Constraining Climate Intervention Impacts Using Observations Following Natural Analogs and Laboratory Experiments.
Solar radiation modification (SRM), including stratospheric aerosol injection (SAI), has been proposed as a temporary measure to limit surface warming while mitigation efforts scale up. Research activity, funding, and commercial interest in SRM are increasing rapidly, heightening the need to understand its potential impact on human and natural systems. Insights into SRM impacts can be gained from existing datasets following natural SRM analog events (e.g., volcanic eruptions, wildfire smoke, and climatic variability) and laboratory experiments. Such observations can also be used to better constrain and evaluate SRM model simulations. This cross–disciplinary session invites contributions that leverage observations from SRM analog events or laboratory studies to assess surface–level impacts. These include, but are not limited to
- observed impacts from SRM analogs
- investigation of underlying physical, chemical, or biological processes-level impact drivers under SRM conditions
- characterization of uncertainties in projecting SRM outcomes
- observation-model comparisons that improve model representation of SRM-relevant processes
