Warmer Diwali Night Reduces Pollution in Lucknow

Strategic Insights -

This year's Diwali celebrations on October 20 saw a bit earlier than usual festivities, resulting in above-normal day and night temperatures in Lucknow. As a result, the pollution levels caused by firecrackers decreased at a faster rate due to warmer conditions. Experts attribute this to the reduced density of the air, which allowed pollutants to clear quickly. The CSIR-IITR director, Bhaskar Narayan, explained that human activities and meteorological conditions also played a significant role in reducing pollution levels.
