The earth’s atmosphere is composed of : Nitrogen – 78%, Oxygen – 21% and the remaining 1% make up the natural greenhouse gases having carbon(iv)oxide – 0.03%.
Before the Industrial Revolution,which began in the 1700s,the earths energy was at a state of equillibrium /stable temperature. This is when the amount of greenhouse gases in the air stayed the same and the rate of energy arriving from the sun was constant.
The Greenhouse gases namely Carbon(iv)oxide,Nitrous oxide,Methane,Water vapour etc prevent long wave radiation from leaving the planet,this warms the earth’s atmosphere making our planet habitable. The enhanced greenhouse effect has been attributed mainly to human activities that have led to a build up of extra greenhouse gases in the atmosphere.
The industrial revolution brought new industrial processes that led to an increase in the burning of fossil fuels,more extensive agriculture and an increase in the world’s population.
The disruption of the earths climate equillibrium caused by increased concentrations of greenhouse gases has led to an increase in global average surface temperatures. This process is called the Enhanced Greenhouse Effect.
