India's capital, Delhi, is facing one of its most severe air pollution crises yet. The government has turned to cloud seeding as a last-ditch attempt to bring cleaner air to the world's most polluted city. This ambitious plan involves adding silver iodide particles to clouds, which are then supposed to induce artificial rain and wash away pollutants.
The Bharatiya Janata party (BJP) has been touting cloud seeding as a solution since it took power earlier this year. However, months of unpredictable weather have put the scheme on hold, only for Delhi's air quality to plummet once again after the Diwali festival. The government has now decided to proceed with the trial, citing favourable conditions.
The first trial flight is set to take place on October 29, and if successful, it will mark a new era in artificial rain over Delhi. However, experts warn that cloud seeding is no panacea and may have limited effects. Dr Shahzad Gani and Dr Krishna AchutaRao, professors at the Centre for Atmospheric Sciences, describe the plan as a "gimmick" that ignores the root causes of pollution.
The two experts also raise concerns about the long-term impact of repeated cloud seeding on agriculture and human health. There is limited research on the effects of chemicals like silver iodide or sodium chloride, which are used in the process. The scientists caution against snake-oil solutions that promise quick fixes without addressing the underlying issues.
Delhi has been ranked as the world's most polluted city for over a decade, with pollution levels skyrocketing during winter months. In 2024, air quality data showed a 6% increase, with particulate matter (PM2.5 and PM10) levels regularly exceeding those seen in Beijing's infamous "airpocalypse" of 2013.
With the cloud seeding experiment set to begin, Delhi residents are left wondering if this will be the solution they've been waiting for. Will it really bring cleaner air to the city? Or is it just another false promise from a government desperate to address its most pressing issue?
