Summary

Story summary

A new study uncovers a startling truth: aquifers in the U.S. Southwest are far more susceptible to climate change than those in the Pacific Northwest. Historical groundwater data shows that while the Southwest's water tables plummeted during previous warming periods, the Pacific Northwest remained resilient. This vulnerability stems from the Southwest's deeper water tables, which rapidly deplete in the absence of rain.
