Climate change significantly increases the risk of water supply stress by mid-century, especially in the western U.S.



We’ve been reading the US National Climate Assessment and found it quite impressive!

We thought we’d share a series of images we think tell the story of what’s going on.

This is the 1st of 9 in the series.

Via the report: “The effects of climate change, primarily associated with increasing temperatures and potential evapotranspiration, are projected to significantly increase water demand across most of the United States. Maps show percent change from 2005 to 2060 in projected demand for water assuming (a) change in population and socioeconomic conditions consistent with the A1B emissions scenario (increasing emissions through the middle of this century, with gradual reductions thereafter), but with no change in climate, and (b) combined changes in population, socioeconomic conditions, and climate according to the A1B emissions scenario.” (U.S. Global Change Research Program)
