A recent analysis by the Envirocatalyst, a research and advisory think tank, has revealed alarming trends in land surface temperatures (LST) across New Delhi's municipal wards over the past decade. The study indicates that the mean LST in Delhi has increased by 3.5 degrees Celsius from 2015 to 2025, with Bhati ward in south Delhi experiencing the most significant rise of 6.1 degrees Celsius. Other wards such as Madanpur Kadhar east and Badarpur also saw substantial increases of 5.9 degrees and 5.7 degrees, respectively. The findings highlight the impact of urbanization, including the replacement of green spaces with constructed areas and the use of heat-absorbing materials. Experts emphasize the need for localized heat adaptation strategies and urban planning to mitigate the effects of rising temperatures. The Envirocatalyst has created a public dashboard to provide live updates on LST changes, aiding in awareness and policy formulation.
