What is climate change? | Start here

The hard facts about global warming – a defining problem of our time. Climate change is happening today, and even world leaders gathered to discuss climate at this year’s Cop25 know we’re not doing enough to stop it. In fact, we are going backwards. The UN says carbon dioxide levels in our atmosphere are increasing and the Earth is on track to warm 3.2 degrees before the end of the century. The consequences of this acceleration are already proving disastrous for communities around the world. This week’s episode of Start Here cuts through science and politics to give you what you need to know about what’s at stake for the planet.
