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.

Australia: Exceptional drought forecast to persist in Tasmania, Victoria, southern South Australia, and from Perth southward; exceptional surpluses in the northwest

Through September 2016, the forecast indicates water surpluses in the north and along central rivers in Australia, with exceptional surpluses in northwest basins. Exceptional drought is forecast to persist in Tasmania, Victoria, southern South Australia, and from Perth southward.

Canada: Widespread water deficits forecast with excecptional deficits in BC, AB, MB, ON, QC, NB, and NL

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
