It's a Code RED for humanity - the world's largest-ever report into climate change has just been published, warning that billions of lives are at immediate risk. The UN report claims global heating is affecting every region on earth with many changes fast becoming irreversible. It's taken three years to complete by the Intergovernmental Panel on Climate Change - a group that looked at more than 14,000 scientific papers. The last time a report this significant into the science of global warming was released was 2013. One of the wider report's lead authors, is Marine Biologist Professor Mark Costello.
