Climate change is the change in the regional or global temperatures that have severe consequences on the biodiversity. It is not natural but rather man-made. It is mainly caused by increased production of greenhouse gases. The Greenhouse gases like water vapor, carbon dioxide, methane, nitrous oxide, and ozone are the gases within the atmosphere that absorb and emit heat radiation. Increasing or decreasing amounts of greenhouse gases within the atmosphere act to either hold in or release more of the heat from the sun. Increase in CO2, WATER VAPOURS, METHANE, etc. results in other environmental problems such as melting of glaciers in the polar regions that further leads to rise in the sea level.
