Western heat wave threatens health in vulnerable communities

by Mary Sewell

PHOENIX — Extreme temperatures like those blistering the American West this week isn’t just annoying; they’re deadly. This week’s record-breaking temperatures are a weather emergency, scientists and health care experts say, with heat responsible for more deaths in the U.S. than all other natural disasters combined. With more frequent and intense heat waves likely because of climate change and the worst drought in modern history, they say communities must better protect the vulnerable, like homeless people and those who live in ethnically and racially diverse low-income neighborhoods.

Phoenix has been baking in temperatures above 115 degrees (46 Celsius) all week. The high Friday hit a record 117 degrees (47 Celsius) after breaking another Thursday at 118 degrees (48 Celsius). Daily records also were set this week in places across the U.S. West, such as Nevada and California, including 128 degrees (53 Celsius) in Death Valley on Thursday.
