A study led by University of Arizona researchers shows that decades of groundwater pumping by humans has depleted Tucson-area aquifers far more than natural climate variation. Published in the journal Water Resources Research, the study provides the first multi-millennial reconstruction for the region that places human impacts on groundwater into long-term context. … [M]odern pumping from the mid-20th century to present day caused twice the drawdown of the water table compared with natural climate fluctuations.
