Urban heat island

Urban heat islands have become a growing concern over the years. An urban heat island is formed when industrial areas absorb and retain heat. Much of the solar energy reaching rural areas is used to evaporate water from plants and soil. In cities, there are less vegetation and exposed soil. Most of the sun's energy is instead absorbed by buildings and asphalt; leading to higher surface temperatures. Vehicles, factories, and heating and cooling units in factories and homes release even more heat. As a result, cities are often 1 to 3 °C (1.8 to 5.4 °F) warmer than other areas near them. Urban heat islands also make the soil drier and absorb less carbon dioxide from emissions.
