(The Center Square) — U.S. senators from Arizona and Nevada have introduced legislation declaring extreme heat a major disaster.

The Extreme Heat Emergency Act from Sens. Ruben Gallego, D-Arizona, and Jacky Rosen, D-Nevada, would “explicitly authorize extreme heat as eligible for a Major Disaster Declaration” by the president of the United States under the Stafford Act, a 1980s law relating to weather events.
