The extreme heat has had widespread impacts, including significant wildfire activity in the Pacific Northwest and Canada. Cities like Denver and Salt Lake City experienced their hottest Julys on record, while other major cities, including Miami and Los Angeles, ranked in their top-5 warmest Julys. The heat has strained water resources, with Lake Mead, the largest U.S. reservoir, hitting a record low. Globally, Europe also faced severe heat waves, leading to wildfires and infrastructure stress. Long-term climate change and a developing El Niño event are intensifying these conditions, making heat waves more frequent and severe.
