The rising heat in Tamil Nadu and across India is beginning to worsen the environment. In 2025, The Hindu reported that mercury levels peaked at 39.2°C and 39.7°C in Nungambakkam and Meenambakkam, respectively. The series of summer forecasts issued by the India Meteorological Department indicates a surge in heatwaves across the country in April.

Similar conditions are expected to follow in subsequent months, calling for a broader programme of tree planting, lake rejuvenation, park and open space design, and green roofs.
