When Cam Ferguson arrived at a spot near Chase Field, the home of the Arizona Diamondbacks in downtown Phoenix, he prepared his usual supplies of cold water, sports drinks, peanuts, and candy about four hours before the first pitch.

The temperatures in downtown Phoenix were expected to reach around 103 degrees Fahrenheit (39.4 degrees Celsius) on a Labor Day afternoon, promising brisk business for vendors like Ferguson.

Despite the scorching heat, Ferguson and other vendors at the game were determined to provide some relief for the fans, pointing out the price difference between buying a bottle of water outside versus inside the stadium.

The summer of 2024 in Phoenix was proving to be exceptionally hot, with the city experiencing its 100th consecutive day of temperatures at or above 100 degrees, breaking previous records. Meteorologist Shawn Benedict from the National Weather Service highlighted the significance of this streak.

Experts attribute the escalating temperatures to climate change caused by human activities, leading to extreme heatwaves, wildfires, severe storms, and prolonged droughts. The relentless heat in Phoenix was evident, with temperatures surpassing 100 degrees Fahrenheit every day since late May.

The upcoming week was expected to bring unseasonably high temperatures across the Western U.S., with extreme heat warnings in effect for cities like Phoenix and Lake Havasu City in Arizona, as well as parts of Nevada and California.

In Maricopa County, Arizona, which includes Phoenix, public health officials reported a concerning number of heat-related deaths so far this year, with many cases still under investigation. The scorching conditions in 2024 were setting records not only in Phoenix but also in other Western states.

Amid the heatwave, California issued red flag warnings due to the increased risk of wildfires. Blazes had already started in some areas, leading to power outages and evacuations. The dangerous heat was a growing concern for residents and outdoor workers alike.

Although Chase Field provided some relief with its air-conditioned facility and closed retractable roof for most games, outdoor workers like Ferguson and landscaping professional Ramiro Lopez had to find ways to cope with the extreme heat during their work shifts.

As the record-breaking summer continued in Phoenix, staying cool and hydrated became essential for survival in the blistering heat. The challenges posed by the relentless heatwave were felt by everyone, especially in low-income communities where access to cooling facilities was limited.

Climatologists emphasized the importance of staying cool and hydrated to mitigate the health risks associated with prolonged exposure to high temperatures.
