The urban heat island effect describes built up areas that are hotter than nearby rural areas. The annual mean air temperature of a city with 1 million people or more can be warmer than its surroundings. But in the evening the difference can be very high. It affects communities by increasing summer time peak energy demand, air conditioning costs and air pollution and greenhouse emission. he impacts of the UHI include increased energy commissions, and elevated emissions of air pollutants and greenhouse gases and impaired water quality

Increasing tree and vegetable cover and creating green roofs are the things that are being done to mitigate or reduce the impact of the UHI.

The aerosols

Aerosols are minute particles suspended in the atmosphere. They are important because their scattering of sunlight can reduce visibility (haze) and redden sunrises and sunsets. An act as sites for chemical reactions to take place (heterogeneous chemistry and large amounts of reactive chlorine and, ultimately, to the destruction of ozone in the stratosphere and those are some natural sources of aerosols in the atmosphere human activity add to atmospheric aerosols because of a large fraction of human-made aerosols come in the form of smoke from burning tropical forests, the major component comes in the form of sulfate aerosols created by the burning of coal and oil. The climate effect of the aerosols will be opposite to the effect of the increasing atmospheric trace gases cooling instead of warming the atmosphere.

The greenhouse effect is gasses that trap heat into the atmosphere. There are three top greenhouse gases and they are Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Fluorinated gases. There are many reasons as to why the greenhouse effect rate has went up over the last couple of years and it’s because of humans. From all the resources that we have from using cars, and using electricity hurts the greenhouse effect more and more. Infrared radiation is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 mm.
