Climate change is one of the most pressing issues facing our nations today—but what is it? Hasn’t it always been happening? What is making it worse? Why do some people deny its happening? 

The concept of climate change and all of its implications is discussed as part of the What's the Issue series. What's the Issue asks ‘what’s all the fuss about?’ It reviews what is at stake when we think about climate change, with the aim of helping young people to understand this difficult subject and provide them with the tools to inform their own opinions on the issue.
