Climate change is one of the biggest threats to us all... Why we?re tackling climate change: We know climate change is happening, and we know that it is caused by our actions. The Earth?s atmosphere is warming, faster than it probably ever has. In some cases weather patterns, climates and natural environments are changing quicker than wildlife or people can adapt. So many of the world?s biggest challenges, from poverty to wildlife extinction, are made more difficult by climate change. And things will get worse if we do nothing. But we can do something about it. We have the knowledge and the technology to reduce our impact on the climate, and ease the pressures on the world?s most vulnerable places, people and wildlife. We just need to make it happen."
