Question

What is global warming

Answer 1

Global warming is when the earth heats up ( the temperture rises ). It happens when greenhouse gases ( carbon dioxide, water vapour, nitrous oxide, and methane ) trap heat and light from the sun in the earth's atmosphere, which increases the temperature.

The radiations from the sun enter the Earth’s atmosphere but are unable to escape. This increases the temperature of the Earth. This is called the greenhouse effect. Gases that cause the greenhouse effect are responsible for increasing the temperature of the Earth and thus contributing to the phenomenon called global warming . Thus Global Warming is an increase in the earth's atmospheric temperatures widely due to an increase in the greenhouse effect resulting especially from pollution.
