Further study required on artificial rain, says Environment Ministry

Even as the Delhi Government presses for the Union Government’s approval to conduct artificial rain in the National Capital Region (NCR) to combat toxic pollution levels, officials from the Environment Ministry caution that the ecological impacts of weather modification need thorough study. Without such research, they warn, unintended consequences could arise.

As pollution continues to choke the Capital, Delhi Environment Minister Gopal Rai reiterated that artificial rain is urgently needed and called for a meeting with the Centre.

Artificial rain, or cloud seeding, involves introducing chemical agents like silver iodide, potassium iodide, or dry ice into clouds using aircraft. These agents enhance cloud density, leading to precipitation and increasing the likelihood of rainfall.

“Layers of smog have engulfed North India. Artificial rain is the only solution to clear the smog. This is a medical emergency, and it is the moral responsibility of Prime Minister Narendra Modi to intervene,” Rai said.

The minister had previously written to Union Environment Minister Bhupender Yadav on August 30 and followed up twice on October 10 and October 23.

Creating artificial rain in Delhi requires collaboration with Central agencies such as the Central Pollution Control Board (CPCB), the India Meteorological Department (IMD) and the Civil Aviation Ministry. However, the presence of clouds is a critical factor for success.

“Currently, there are no clouds over Delhi,” an Environment Ministry official explained. “Additionally, artificial rain in one region can impact another, potentially leading to issues like desertification. Weather modification is a complex and ongoing field of study. The success of artificial rain projects varies by region, and success in one country does not guarantee the same outcome here.”

The official further cautioned against interfering with natural processes, warning of potential risks associated with such interventions.
