Natural causes of global warming include the emissions of methane from the Arctic and the wet lands, climate change, volcanoes, etc. Methane, a greenhouse gases keeping the heat in the Earth's atmosphere, are emitted in large quantities at the North Pole and the wet lands. In the case of the volcano, when a volcanic eruption, tons of ash were discharged into the atmosphere. Also the earth rotates around the Sun is elliptical so the Earth at near, at away with the Sun. comets fly about the Earth with high velocities will carry a chemical gas flow increases the heat of the Earth up. Whether nature has contributed to global warming, but the contributions are not significant when compared to the part of the people against this risk. Until now scientists have yet to find a permanent solution, but we still have a way to slow and reduce the phenomenon of global warming of the Earth. And in my opinion, all of which is by the consciousness of every human. Sweed will clarify the consequences vs how to solve global warming
