Question:

How is excessive content of CO2 responsible for global warming?

Answer:

Carbon dioxide is a very essential gas for our survival. However, an increased content of CO2 in atmosphere causes a serious threat. An increment in the combustion of fossil fuels, decomposition of limestone, and decrease in the number of trees has led to greater levels of carbon dioxide. Carbon dioxide has property of trapping the heat provided by sunrays. Higher the level of carbon dioxide, higher is the amount of heat trapped. This results in an increase in the atmospheric temperature, therefore causing global warming.
