This is the long-term warming of the overall temperature of the planet.

In other words, it is the long-term heating of the Earth’s surface that has been observed since the pre-industrial period (1850-1900) due to human activities and the burning of fossil fuels. Fossil fuels include coal, oil, and natural gas. Burning these fossil fuels leads to a phenomenon known as the “Greenhouse effect” on the earth’s atmosphere.


What is the Greenhouse Effect?

This is a phenomenon that comes into play when the sun’s rays penetrate the earth’s atmosphere, but due to the gasses produced by fossil fuels, when the heat from the sun’s rays is reflected off the surface it cannot escape back into space. Examples of greenhouse gases are Carbon dioxide, chlorofluorocarbons, water vapour, methane, and nitrous oxide. The accumulation of heat in the atmosphere has led to the rise of the average global temperature which is otherwise known as Global warming.
