Climate change is real and without urgent action it will devastate life on earth.
Hundreds of millions of people, particularly the world's poorest and most vulnerable, will be put at severe risk of drought, floods, starvation, and disease. By the middle of the century up to one third of land-based species could face extinction.
This section provides a simple introduction to the basics of climate change, the key scientific evidence and the potentially massive impacts on life as we know it. It also explains the action we need to take to stop climate change before it's too late.
