The 5 Times of the Biosphere – Beyond Braudel Legacy Red : Alert on the Big Blue

Life and Earth Sciences and Human and Social Sciences can be brought together under the umbrella of biogeography to guide us in explaining the order and disorder of a world in perpetual motion. We are currently experiencing accelerating climate change, which is calling into question the foundations of many civilisations. The subject of Fernand Braudel's pioneering geohistorical work, the Mediterranean and the Mediterranean world offer a concrete space for renewed reflection on Time and its rhythms. Extending the Braudelian concept of the '3 Times' of History, our reflection opens onto the '5 Times' of the Biosphere, a concept born of biogeohistorical reflection committed to responding to the major challenges of climate disruption and the upheavals of the Earth, which overdetermine the life of living communities, of which humanity is a part. Geology and Climatology have to be crossed with legacy of History to understand the way Mediterranean sea is on : Red alert on the Big Blue.
