Question

Excessive burning of fossil fuels is a major cause of Global Warming.
A. True
B. False

Answer 1

The term Global Warming can be defined as the increase in the average global temperature of the Earth at an alarming rate. Global Warming is caused due to an increase in the concentration of the carbon dioxide and other pollutants which trap the heat radiated by the Earth surface.

Complete step by step answer:
Global warming occurs when there is an increase in the concentration of the carbon dioxide ($C{O_2}$ ) and other air pollutants and greenhouse gases in the atmosphere. These pollutants and greenhouse gases absorb sunlight and solar radiation that get bounced back from the earth’s surface and try to move into space. Normally, this radiation would escape into space but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the increase in the global temperature of the planet. That's what we call the greenhouse effect. In many countries, the burning of fossil fuels to produce electricity is the largest source of production of heat-trapping pollutants, producing about two billion tons of $C{O_2}$ every year. Coal-burning power plants are by far the biggest polluters as there has been a mass usage of coal to produce heat energy which helps in the further production of electricity.
Hence, the correct option is A. True.

Note:
During the procedure of electricity production in coal power plants, there is an emission of a huge amount of carbon dioxide gas along with ashes. The world’s second-largest source of carbon dioxide pollution is the transportation sector, which generates about 1.7 billion tons of $C{O_2}$ in a year.
