There are some natural factors like Volcano activity, Ocean currents, Continental drifts that cause change in climate but also, man-made factors like Green House Gas emission GHG, release of Aerosols in atmosphere like CFC (Chloro Fluoro Carbons) & HFC’s (Hydro Fluoro Carbons). The CFCs damage the UV layer in atmosphere which is very dangerous. Deforestation and reduced agricultural area due to rise in Industries also adversely affects the climate change, and can lead to even worse conditions.

Our Prime Minister, Narendra Modi called for International Solar Alliance at COP21 Paris. 121 countries have already joined and ISA is operational in Gurgaon, Haryana.
