Your questions answered: The speed of global warming; space junk; advice for kids

Climate Question listeners take over the programme again, putting their queries to Graihagh Jackson and her panel: BBC climate editor Justin Rowlatt, Bloomberg News senior climate reporter Akshat Rathi and the presenter of BBC CrowdScience Caroline Steel.

One listener asks why the climate appears to have changed so dramatically and fast in the last 50 years. Another wonders whether "space junk" plays a role in global warming. Plus, a question from a five-year old and - in a first for the programme - a listener's climate song!
