From the Azores to Svalbard, a journey by foot, sailboat and electric motorbike along the Gulf Stream and through six countries, discovering a Europe that is gearing up to deal with the transformations of climate change. The Gulf Stream is a key element of the European climate, warming lands otherwise covered by ice and bringing rain from Portugal to Russia. Now it is gradually weakening and if it were to diminish further, Britain would end up resembling Sibe­ria, rainfall would be reduced and the desert would advance southwards. How are communities, cities and ecosystems reacting to all this? This compelling reportage tells the story of a changing Europe, from communities born from Scotland’s oil that are converting to renewable energy, to young Spaniards returning to the land of their fathers to imagine a new sustainable agriculture. It describes the abandonment of the coasts of the Bay of Biscay due to the collapse of fishing, the renaturalisation of an increasingly wild Europe, the difficult coexistence with wildlife (after the great return of the lynx and the wolf).
