Delhi's Air Pollution Plunges Under Cloud Seeding Experiment
The Indian capital is about to get a taste of artificial rain as part of an ambitious cloud seeding experiment aimed at purifying its notorious smog. The Delhi regional government has kicked off trials for this novel approach, which involves dispersing silver iodide into clouds to induce precipitation and wash away pollutants.
Experts say while the technique may yield some benefits, it is by no means a panacea for Delhi's choking air. Cloud seeding can lead to heavier rainfall, but its impact often proves marginal, and it requires suitable cloud conditions β which are scarce over the city during winter when pollution peaks.
Critics of the plan have described it as a "gimmick" with little scientific backing or consideration for long-term consequences on agriculture and human health. Delhi's Centre for Atmospheric Sciences has condemned the initiative, likening it to a previous ill-fated project known as "smog towers," which spent billions of rupees without yielding significant improvements in air quality.
The warning from climate scientists is clear: these "snake-oil solutions" are unlikely to clear the air and can have unforeseen consequences. Delhi's pollution levels have skyrocketed, with PM2.5 and PM10 readings frequently exceeding those seen in Beijing during its infamous 2013 "airpocalypse."
For now, Delhi residents will have to endure the hazy skies as scientists monitor the results of this novel approach to combating air pollution.
