Many people think climate change caused Classic Maya civilization to collapse abruptly around 900 A.D. An archaeologist says that view is too simplistic and misses the bigger point. Carbon dioxide concentrations in Earth’s atmosphere have reached 415 parts per million – a level that last occurred more than three million years ago, long before the evolution of[…]
Modern civilizations might also be less capable of recovering from deep collapse than their predecessors. Is the collapse of a civilisation necessarily calamitous? The failure of the Egyptian Old Kingdom towards the end of the 2nd millennium BCE was accompanied by riots, tomb-raids and even cannibalism. ‘The whole of Upper Egypt died of hunger and[…]

In 1859 Versailles and its more than twenty neighboring communities were presented with the new Marly Machine—a hydraulic pump that formed the cornerstone of Versailles’ drinking water supply. This event reinforced the dependence of Versailles on the Seine River and the[…]
Up until this epoch, water resources consisted of an old and damaged medieval aqueduct. Operational since 1847, the 80 kilometer long Canal de Marseille, built by famous Swiss civil engineer Franz Mayor de Montricher, has allowed great improvement in the water supply in the city of Marseille, southeast of France. Indeed, during the first quarter[…]
In the last years of his life, Dante Alighieri was an unsuspecting witness to a rapid shift in climatic conditions that led to cooler and wetter weather all over the continent.
