One important cause ( Methane)

The increase in temperature help methane to goes up to air from ice and water. Methane is stronger than carbon dioxide as a green house gas. According to scientists, Methane has big hand in global warming. In the past, when the earth’s temperature goes up to dangerous level such as 6 degrees above normal, the earth’s temperature then increased an additional 11 degrees. Methane is stored in the earths oceans and is released when the temperature increases and pressure goes down. Also, methane can be found in ice. When ice melts, methane stored in the ice is released. Scientists fear that if the earth reaches a dangerous temperature, it would be impossible to turn back and we have to face big problem in global warming.
