Is the Past Decade of Persistent Drought In Brazil a New Normal?

A sixty-year record of extreme weather conditions shows a disturbing pattern of deficit surface water conditions throughout Amazonia.The Water Security Indicators Model (WSIM) developed by ISCIENCES LLC is used to examine average monthly hydrological conditions throughout the basin. An apparent correlation with the emergence of temperature extremes over the same period begs the question whether man-made climate change is the root cause.The literature however points to man-made deforestation as the critical factor, raising concern that "the Amazon is losing the ability to control it's own climate." If true, consequences will have profound impact on the region and the global environment.

United States: Water Forecast Indicates Deficits in the Northwest, Surpluses in the Central Plains
