Freshwater, drought, and climate change

Lack of freshwater for human consumption and agricultural use is a growing and very serious problem globally–including in rich countries like the United States.  As an example, rivers in many countries are experiencing significantly reduced flows due to warmer temperatures, longer and more frequent droughts, less snow and less winter precipitation, and the need to serve more and more people. Quick bibliography: Recent research about…
