Mexico Bans Solar Geoengineering After Weather Balloon Incident

Mexico is drafting new regulations to prohibit solar geoengineering within its national territory and plans to rally other countries to ban the climate strategy. The move comes after a US startup called Make Sunsets released two weather balloons containing sulfur dioxide into the air in Mexico's Baja California, violating the country's national sovereignty. The incident has set off a series of responses that could set the rules for future study of geoengineering, especially by private companies, in Mexico and around the world. While some scientists and policy makers are urging further study of solar geoengineering, others remain opposed, arguing that large-scale interventions in the atmosphere risk triggering extreme and unpredictable weather changes.
