Greenhouse Effect

Greenhouse Effect

The term ‘greenhouse effect’ refers to the process of thermal radiation from the surface of a planet being absorbed by greenhouse gases in the atmosphere and then being re-radiated in different directions, including back towards the Earth’s surface. This results in temperatures rising higher than they should. The natural greenhouse through which the earth operates makes life possible. Human activities, however, have resulted in the increase of some greenhouse gases, including water vapour, carbon dioxide, methane and ozone, leading to a greater greenhouse effect and thus an increase in global warming.
