Nighttime temperatures played a significant role in the recent heat wave. A new record was set for the hottest minimum temperatures, exceeding the previous record by a notable margin. This trend is often linked to climate change, according to scientific findings.

The heat wave affected various regions, with some areas experiencing more extreme conditions than others. Certain parts of the country, such as the Mountain West and Southeast, were particularly affected by the high temperatures. Further information on this record-breaking heat wave is available from the National Oceanic and Atmospheric Administration, which reported on the unusually hot conditions across the Lower 48 states.
