How the deep ocean is being negatively affected by climate change – we hear from two of Britain's top marine biologists.

Also in the programme: security forces in Sri Lanka say six children were among those killed when Islamist militants blew themselves up during clashes in the east of the country.

Joining Rebecca Kesby to discuss these and other issues are Dr Helen Scales, a marine biologist and writer, and John Carlin, a journalist and writer.
