12.00pm The Big Freeze

Earth has plummeted into periods of intense cold, time after time. Some of these drops in global temperature are caused by volcanic eruptions. Despite only lasting a few years, they have the power to cause huge social and political upheaval across the entire world. But the oceans can trigger far bigger, thousand-year freezes. These have the power to trigger mass extinctions and global catastrophes. Worryingly, recent evidence suggests we might be heading towards one of these freezes and, in a bizarre twist, the thing that could trigger it is global warming.
