hey dear
Greenhouse gases from human activitiesare the most significant driver of observed climate change since the mid-20thcentury.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.

Greenhouse effect is caused by various green house gases in the atmosphere. All the green house gases available in the atmosphere allow the passage of short wavelengths of visible lights of sun through the transparent medium, absorb heat and check the infrared radiations of longer wavelength to pass back to the space. In this way green house gases trap the heat from long wavelength radiations which result in increased temperature of the earth’s surface. Our earth’s surface is getting warm day by day causing climate change, weather patterns change and declining the healthy living of human beings, plants and animals.
