Observed Regional Changes

Over the past few decades, Northern Arizona has gotten warmer, resulting in reduced water availability. The impacts of these changes vary throughout our region. For example, the U.S. Geological Society studied the changes in the land where the Navajo Nation resides and found that streams that flowed in the 1980's are now dry washes that never, or rarely flow. These hotter temperatures increase evaporation, making the soil drier and unsuitable for most plants. As a result, sand dunes are growing. To learn more about the impacts of climate change on Navajo Nation watch this video produced by the U.S. Geological Society.
