WATERSHED: "That area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community."
- John Wesley Powell

Water and Climate
By nature, climate is largely defined by the presence or absence of water, along with the temperature and elevation profiles that determine the state of matter water assumes. Particularly, the Köppen climate classification system makes one point abundantly clear: water is essential in any assessment of climate.
Modern science, and our experience traveling around the world speaking to communities about the issues which concern them most, leads us to believe that Earth’s climate is changing and its cause is anthropogenic. Regions of the world are experiencing unprecedented climatic extremes—between wet and dry, hot and cold—and leading researchers suggest these shifts will be exacerbated as the level of greenhouse gasses in our atmosphere continues to rise.
As the climate changes, so does the availability and access to water. Once water-rich areas are now dry, and once perennially frozen regions are melting to reveal new resources. All these developments pose significant threats to fragile ecosystems and levels of biodiversity.
Blue Legacy is investigating the effects climate change is having right now by visiting communities around the world in order to document firsthand the shifting landscape and discover how people are preparing to adapt to a changing world where water is a major source of uncertainty.
