Indian cities have changed a lot because of people moving to cities and buildings being constructed. One big problem that has come up is the development of Urban Heat Islands. This is when cities like Delhi, Mumbai and Bengaluru get hotter than the areas around them. Urban Heat Islands are connected to climate change the way we use land, and losing spaces. This paper looks at what causes Urban Heat Islands how they affect people and the environment and where they are found in India. We used maps and satellite images to understand how heat is distributed in cities for example Hyderabad and Chennai. We found that as cities grow heat stress gets worse affecting people’s health the environment and the economy. In this research paper discussed about ways to make cities cooler like planting trees using roofs that reflect heat and planning cities in a way that considers the climate.
