The record-breaking heat and drought conditions have had widespread impacts, including stress on water resources, agriculture, and ecosystems. Low streamflow and reservoir levels threaten water availability for communities and irrigation, while high evaporation rates worsen soil dryness. These conditions increase the risk of wildfires and reduce crop yields, potentially affecting food supply chains. The western U.S. is particularly vulnerable due to its reliance on snowpack for water storage, which was at historic lows in 2026.
