Summary:
- The article discusses a proposed climate change solution called geoengineering, which involves modifying the Earth's atmosphere to reduce the effects of global warming.
- It explains that one geoengineering method, called solar radiation management, has been tested and found to have unintended consequences, such as disrupting weather patterns and causing droughts in some regions.
- The article warns that geoengineering could be a "catastrophic" solution to climate change, and that more research is needed to understand the potential risks and side effects before implementing such large-scale interventions.
