California is not the only place who’s suffering historical droughts. The Canteira system is at its lowest level on record, posing a serious threat to water provisions of South-America’s largest city Sao Paullo. The government was forced months ago to install daily rationing. If the current situation doesn’t change dramaticcaly, Sao Paola can fall dry by February next year. Brazil relies heavily on hydropower and has to start up very polluting coal plants since no water means no hydropower. In the meantime, many speculate about the reasons behind this unseen drought. Antonio Nobre (one of country’s most respected Earth scientists and climatologists) believes the far going deforestation in the Amazon and the almost complete disappearance of the Atlantic forest are the main reason. The forest used to cool down the region and inforced a water cycle which is now broken.
