Greenhouse Effect and Global warming: Evidence, causes, and consequences, with reference to Africa... Argumentative Essay​

The greenhouse effect is the process thanks to which Earth has a higher temperature than it would have without it. The gases that radiate heat also known as greenhouse gases absorb the energy radiated out by the Earth and reflect a part of it back to Earth. Of all the energy that the Earth receives from the Sun, a part of it around 26% is reflected back to space by the atmosphere and clouds. Some part of it is absorbed by the atmosphere, around 19%.

If an ideal black body were at the same distance from the Sun as Earth, its temperature would be 5.3oC. However, Earth reflects 30% of this energy back into space. Including this in the calculation for the temperature of Earth gives us an answer of -18oC. As we can clearly see, this is far from true. The average temperature is a whopping 33oC higher at 15oC. This difference in ambient temperature is caused by greenhouse gases.

Global Warming refers to the increasing temperature of the Earth’s climate system and its related effects. Scientific evidence has conclusively proven that the Earth’s temperature is in fact rising and has risen by 0.85oC. This has an impact has affected different regions differently. The effects include rising sea levels, retreating glaciers, loss of sea ice in the poles, warming global temperatures, changing precipitation, expansion of deserts etc.
