The enhanced greenhouse effect is an elevated and imbalanced greenhouse effect, caused by human activities and pollutions. The greenhouse effect is when the Earth and its gases are in balance with each other in order to promote growth and sustainability.
Since the Industrial Revolution, the Earth's carbon dioxide, methane and nitrous oxide levels have risen immensely. The burning of fossil fuels, some farming practices, production and industrial companies and deforestation all emit harmful gases in to the atmosphere. The additional release of these gases has caused the Earth's surface temperatures to rise, an increase in natural forest fires, rising sea levels, melting glaciers, and odd and extreme weather patterns.
Over the past 100 years, the overall temperature of the Earth has risen 0.7 degrees Celsius, according to the Australian Academy of Science. The natural greenhouse effect allows for the sun to heat the Earth's surface by passing through the atmosphere. Once the Earth's surface is warm, it radiates that energy back toward the atmosphere where gases are absorbed and turned into energy and dispersed back toward the surface. With the occurrence of the enhanced greenhouse effect, the atmosphere has been lowered and the amount of gases that are absorbed have decreased, leaving them trapped and causing temperatures to rise.
