Factors Contributing To Global Warming
Global warming is defined as rise in the average temperature of Earth, surface air and oceans. According to the studies conducted, it has been explained that the Earth’s temperature has risen by nearly 1 degree Fahrenheit in the last 100 years. It is one of the major environmental problems today. If this situation continues, then many adverse effects may take place on earth.
Global warming can be caused due to natural calamities or human activities. Natural causes of global warming include bursting of sunspots, solar output variations, volcanic explosions and changes in the Earth’s orbit. Human activities, which increase green house gases, including burning of solid waste, wood, and fossil fuels such as oil, natural gas and coal, and deforestation. Release of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) from industrial processes generates more heat than normal and gets trapped in the atmosphere resulting in global warming.
The main gases contributing to this are carbon dioxide, water vapor, methane, and nitrous oxide. These gases are largely produced by thermal power plants that burn the fossil fuels, road vehicles, and industries. Another cause is deforestation, which is caused by cutting and burning of forests for building houses and industries.
