**3. Air pollution and climate change**

Air pollution is directly linked to the climate change and global warming. Some of the effects include rising sea levels, heatwaves that happen more often, droughts, and extreme weather events such as hurricanes, floods, and wildfires. The loss of biodiversity and changes in agricultural production are also the negative outcomes of the climate change. Almost all kinds of air pollutants are directly or indirectly involved in global warming resulting in uncertain climatic conditions. For instance, emissions from vehicles, industries, and domestic activities including combustion by-products comprising of carbon mono oxide, carbon dioxide, nitrogen oxides as well as char particles (in the form of particulate matter). Such particulate matters absorb or scatter radiation with greater capacity as compared to air and hence impart a direct impact on climate change, which may harm human, animal as well as plant health. Similarly, methane is another pollutant that contributes to climate change as its global warming potential is much higher than carbon dioxide. Possible options to cope with climatic issues and ambient air quality include an improvement in the environmentally efficient energy generation systems, less thermal losses, and use of clean energy resources to reduce emission levels around the globe [39–42]. Controlling air pollutant can have a direct and positive impact on the climate change and improves quality of

environment. For this, it is very important to revise the policies for energy generation, which can minimize the consumption of fossil fuels.
