If you missed the fantastic 'Climate Change: Simple, Serious & Solvable' event you can re-watch it here.
Dr. James Rae joined us to explore just what climate change is, why it’s so serious and how we can go about solving it.
Today, Dr. Rae returns to help investigate climate science further, answer any questions and give advice on sustainable lifestyles by responding to questions put forward by our followers on social media.
