Much of Earth’s human population, and much of its wildlife, depend on groundwater and springs for fresh water supplies. However, climate change, and particularly reduced and more quickly evaporating snow, limit infiltration and aquifer recharge. This is particularly true for springs that emerge from shallow basalt aquifers, such as those around us here in northern Arizona.
