UN reveals landmark climate report

The world's largest ever report into climate change is published, setting out the stark reality of the state of the planet. The report "is a code red for humanity", says the UN chief. One of the report authors, Dr Friederike Otto, told Newshour that climate change’s tipping point is a decade earlier but urgent actions could help reverse.
