DOES THE GREENHOUSE EFFECT OCCUR NATURALLY?
Yes, it does. The greenhouse effect is a natural process which made life on Earth possible. Without naturally occurring greenhouse gases such as water vapour, carbon dioxide, methane and nitrous oxide, the Earth’s surface temperature would be 33C cooler – a chilly -18C rather than the tolerable 15C. However, since the beginning of industrialization, 200 years ago, concentrations of these gases have increased substantially . It is estimated that the Earth’s average temperature has risen by 0.5 to 0.6C since 1880 because of emissions of greenhouse gases from human activity. The main sources of these emissions, particularly carbon dioxide, methane and nitrous oxide, are the combustion of large amounts of fossil fuels in the energy and transport sectors, deforestation and the use of intensive farming methods. When we talk about the greenhouse effect we mean the ENHANCED effect which is caused by the increase of greenhouse gases from human sources.
