December precipitation ranged from average to much-below average across most of Arizona, with record-dry conditions along the western edge of Arizona. Above-average temperatures and below-normal precipitation are reflected in the expanding areas of drought designation in the Jan. 17 U.S. Drought Monito, with Arizona documenting increases in extent and intensity of drought since the December outlook.
The UA is an international leader in climate science, impacts and policy. We use paleoenvironmental techniques to reconstruct past climates and computer models to understand future conditions. We look at how patterns of drought and heatwaves change and cause water shortages, increase wildfire risks, reduce crop production and food security, threaten defense installations, and affect human health and ecosystems. We work with partners to deliver usable climate science and to create effective responses that help people focus on adaptation, resilience, and risk reduction in the face of climate change.
