The world, therefore human kind, is facing perhaps its biggest challenge in the 21 century. Climate change is highly under estimated by the governments. It will lead to poverty, food shortage, diseases and maybe even to war. The temperature around the globe will rise with 2 C and this means catastrophic consequences. It is likely to have more tornados, tsunamis and other extreme weather events. I believe this a very frightening matter and that the world leaders should pay more attention to the thorough problems.
