As temperatures soar above 40°C in several areas, climate scientists warn that the widespread burning of trash could exacerbate the heat. Pune is witnessing a surge in illegal waste burning, particularly along Pashan-Sus Road, Kalyani Nagar, Undri, Manjari, and Kothrud. Apart from polluting the air and posing health risks, this practice leads to immediate temperature spikes in the vicinity, with the combustion process releasing heat and emissions that contribute to local warming.
Experts from institutions like the National Institute of Advanced Studies and the Indian Institute of Tropical Meteorology emphasize the adverse effects of garbage burning on climate. The release of greenhouse gases like carbon dioxide traps solar radiation near the Earth's surface, contributing to long-term warming. Moreover, the burning of plastic releases toxic dioxins, threatening soil microbiota and insect diversity. Residents are calling for stricter penalties to deter this harmful practice, noting its contribution to groundwater contamination and urban heat island effects.
