Researchers who help global warming make clear it as follows International warming will be the phenomenon of rise in temperature on the atmosphere. This rise in temperature is due to excessive emission of carbon dioxide and inexperienced dwelling gases by burning of fossil fuels. Carbon dioxide is often a eco-friendly house gas; a eco-friendly home gasoline won’t allow the reflected sunrays by earth surface to exit the atmosphere. This too much accumulation of CO2 and various environmentally friendly residence gases leads to increase with the atmospheric temperature. World-wide warming may possibly cause melting of glaciers and polar ice caps, which in the end boost the ocean stage.
