The jury is in. Climate change is real. Water crises, both global and local, are too.
Data, with graphs of interrelationships and implications over time, spurs us to shred assumptions, gain perspective, and forge a sound course of action. The studies below look back to discover trends, or ahead to project likelihood and impact. They ask, and answer:
- Global temperatures? Rising. 
- Hottest global year on record? 2015, with 2014 2nd hottest. 
- Local temperatures? Local rainfall? Rising. Dropping. [3, 4]
- Top global risk to economies, environment, people? Water crisis. [5, 6]
- 21st C. extended drought conditions in U.S. Southwest & Central Plains? Worst in 1,000 years. [7, 8]
My take on all this doom and gloom? Do what I can to adapt to rising temperatures and lack of freshwater, and take a bite out of demand with water-efficient practices.
