While most geoengineering proposals are fairly large-scale, local interventions to tinker with weather systems are fairly common at this point.

Cloud “seeding” for instance, is a fairly well-established practice where moist clouds are artificially injected with chemicals such as silver iodide, a practice that leads to rain. Maharashtra has considered using the practice for drought-stricken regions and there was talk that Delhi might use cloud seeding techniques to counter air pollution as well.

Geoengineering has its shares of supporters and detractors. The former argue that tech-driven “solutions” are critical for countering climate change, especially given its rapid pace and the seeming inability of governments to coordinate an sufficient response.
