Question

What is the difference between the local and global air pollution??
​

Answer 1

local pollution causes in a particular region.

but

global pollution causes throughout a country or over world.

Answer 2

Although both air pollution and global warming are different concepts yet they are interlinked in more than one ways. While air pollution can be defined as a local phenomenon of drop in air quality, global warming, as the name implies, is the unusual increase in concentration of green house gases in the atmosphere.

Nevertheless, one factor that is responsible for both the phenomena is the extraction and burning of fossil fuels- in automobiles, industries, power plants etc. The burning of fossil fuel yields not only pollutants like particulate matter,NO2, SO2 etc. but also heat-trapping gases like CO2. While the pollutants are primarily responsible polluting the air, the green house gases are actually heating up the atmosphere.

Moreover, there is another category of pollutants that are contributing both to air pollution and climate change. These are known as Short-Lived Climate-forcing Pollutants (SLCPs). This category includes methane, black carbon, ground-level ozone, and sulfate aerosols. However, the impact of these pollutants towards climate change is quite varied. While SLCPs like particulate sulphates are cooling the Earth by reflecting the incoming sunlight; others like Methane and Black carbon are heating the atmosphere by absorbing the same.
