Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from Utrecht University. But how likely is it that this will actually happen in the real world? Presenter Victoria Gill speaks to Jonathan Bamber who cautions that a gulf stream collapse is not imminent, and that it may just weaken slowly over time.

But that ice-free season is getting longer, depriving the bears of that frozen platform that they use to pounce on their favourite prey – seals. So what do the bears do all summer?
