In a study prepared for the National Resources Defense Council (NRDC), Tetra Tech noted the potential risk to water resources resulting from global warming. The study finds that half the counties in the lower 48 states face potential water shortages by 2050.
The study concludes in part that “as this analysis highlights, the impacts of climate change will greatly increase the number of areas where renewable water supply will be lower than withdrawal, therefore increasing the number of areas vulnerable to future water shortages.”
