What is cloud seeding and how does it work?
Cloud seeding involves dispersing substances like silver iodide into clouds to encourage rainfall. The goal is to induce rain that can wash away pollutants and temporarily improve air quality. However, its success depends on weather conditions and the type of clouds present.
-
Can cloud seeding really reduce pollution in Delhi?
While cloud seeding can potentially bring short-term relief by inducing rain, experts warn that its overall impact on pollution levels is limited. It is considered a temporary fix and does not address the root causes of pollution like vehicle emissions and industrial activity.
-
Is cloud seeding safe for health and the environment?
There are concerns about the safety of cloud seeding chemicals, such as silver iodide, which may pose health risks if used extensively. Critics argue that the long-term environmental impacts are not fully understood, making it a controversial approach.
-
What are the limitations of cloud seeding as a pollution solution?
Cloud seeding's effectiveness is uncertain and highly dependent on weather conditions. It offers only a short-term reduction in pollution and does not replace comprehensive policies aimed at reducing emissions from vehicles, industry, and agriculture.
-
What other measures are needed to fight Delhi’s air pollution?
Long-term solutions include stricter emission controls, promoting cleaner fuels, improving public transportation, and reducing crop residue burning. Cloud seeding should be viewed as a supplementary measure rather than a primary solution.
-
Are there similar cloud seeding projects elsewhere?
Yes, cloud seeding has been used in various countries for weather modification, drought relief, and hail suppression. Its application for pollution control remains experimental and debated among scientists and policymakers.
