India has embarked on a novel experiment to tackle its notorious air pollution by seeding clouds with silver iodide over Delhi, hoping to bring down toxic fumes. The plan was proposed by the Bharatiya Janata party (BJP) which came into power earlier this year and has been touted as a means to combat the city's suffocating smog.
The technique, known as cloud seeding, involves dispersing silver iodide particles into clouds, which then stimulate rain formation. This may potentially wash away pollutants but experts are skeptical about its efficacy. According to two professors at Delhi's Centre for Atmospheric Sciences, it is an "unsuitable remedy" that lacks scientific backing and poses unknown risks.
While the government has set October 29 as a target date for the city's first artificial rain, critics argue that this is merely a short-term fix without addressing the root causes of pollution. The experts point to the lack of research into long-term effects on agriculture and human health due to repeated use of chemicals used in cloud seeding.
Delhi has been named the world's most polluted city for over a decade now, with pollution levels spiking by 6% in 2024 compared to the previous year. The city's notorious smog problem is worsened during winters when fine particulate matter (PM2.5 and PM10) exceeds Beijing's infamous airpocalypse levels from 2013.
The government's plan may be met with a mix of optimism and skepticism as it seeks to alleviate Delhi's severe pollution crisis.
