Science: Extreme weather drives European voters green

Science commentator Laurie Winkless joins Kathryn to talk about three new studies. The first shows evidence from 25 European countries that over the course of a decade extreme heat is directly influencing voting choices - with an increase in Green parties' support. GPS data from Manx shearwater birds found they're impacted by the sun's changes as they navigate long distances to their feeding grounds and back again. And a new dwarf planet's been discovered in our solar system. Laurie Winkless is a physicist and science writer
