Key Background

A heat wave across the South, Southwest and the Pacific Northwest has already broken single-day temperature records for several cities—including Phoenix, Austin and Sacramento, among others—as officials warn of excessive heat. Scientists say the heat wave is complemented by El Niño, a weather phenomenon that brings warmer air north.
