Essay on Greenhouse Effect
Answers
GREENHOUSE EFFECT
The greenhouse effect refers to the warming of the surface of Earth caused by the presence of greenhouse gases in the atmosphere. The presence of radiatively active gases in the atmosphere spreads its energy in all directions and a part of these gases is also directed towards planet’s surface making it warmer. The intensity of the radiation depends on the amount of greenhouse gases in the atmosphere and the temperature of the Earth’s atmosphere. The primary greenhouse gases are carbon dioxide, water vapor, ozone, nitrous oxide and methane.
Greenhouse effect occurs naturally but has increased mainly due to human activities such as clearing forests, burning fossil fuels and so on which has resulted in global warming. Since the beginning of industrial revolution, the amount of methane in the atmosphere has doubled and the amount of carbon dioxide has also increased by approx 30 percent.
The increase in emission of greenhouse gases in the atmosphere has altered the climate of our planet and can alter it further. This will result in extreme drought and rainfall that will disrupt the production of food in various regions. Biodiversity, ecosystem and life of people is adversely affected due to global warming caused because of greenhouses gases. Global warming is a major issue worldwide that needs to be prevented by taking serious measures.
