The article discusses the eruption of Mount Tambora in 1815, which caused a year without summer due to the emissions that blocked out the sun and led to famines and epidemics. It then explores the concept of geoengineering, specifically solar radiation management, as a potential solution to global warming, but highlights the risks and challenges associated with these interventions. The article concludes by emphasizing the need for further research and caution in pursuing geoengineering approaches.
