Heatwave Grips Phoenix: Record Streak of Extreme Heat Raises Concerns for Health and Environment

Phoenix, Arizona, is experiencing a record-breaking heatwave with 18 consecutive days of temperatures reaching 110 degrees Fahrenheit or higher, surpassing a 49-year-old record. The scorching temperatures are testing the resilience of residents and putting vulnerable populations, such as the homeless, at risk. The monsoon season, which typically brings relief, has been delayed, exacerbating the extreme heat. The heatwave is not limited to Phoenix, as hot and humid conditions are expected to worsen across the South, with about 100 million people under heat alerts. The persistent heat is attributed to a high-pressure system and while it is unclear if climate change is to blame, it likely contributes to higher daily temperatures.
