Global Warming is the increase in Earth's mean surface temperature because of the effect of greenhouse gases. These gases absorb long wave radiations and warm the atmosphere, and this process is called as Greenhouse effect. It had led to many changes on the planet, such as rise in sea level; massive melting of snow and land ice, elevated heat content of the oceans, increased humidity, change in the timings of seasonal events, and many others. The main greenhouse gases, namely:Carbon dioxide (CO2); Methane (CH4); Nitrous oxide (N2O); Hydrofluorocarbons (HFCs); Perfluorocarbons (PFCs); and Sulphur hexafluoride (SF6).
