So, while weather fluctuations will continue, climate change is certainly a key driver of Phoenix's escalating heat, and that heat will only worsen until carbon emissions are curtailed. This is taking place against a background of atmospheric carbon dioxide levels that have risen more than 30% since the early 1970s. While the current heatwave has been amplified by a natural El Niño cycle, the baseline climate in Phoenix has grown significantly hotter over the past 50 years as evidenced by rising annual averages and nighttime lows. The data clearly shows that Phoenix is experiencing a long-term warming trend even if daily temperature records are variable. But it does correlate, especially when considering averages over time (which would smooth out fluctuations due to other factors). That’s why global temperature doesn’t scale linearly with rising carbon dioxide temperatures. Likewise, there are other factors that influence temperature. El Niño years are hotter, but growing carbon dioxide concentrations on top of that leads to rising average temperatures over time - and sometimes individual record temperatures. This is climate change in an El Niño year. Thus, the high temperatures are not solely climate change. What is happening now is weather fluctuations that are taking place on top of a baseline temperature that has increased significantly in the past few decades. The all-time highest daily average temperature record was also broken with an average temperature of 108 degrees. We are now approaching an entire month with daily temperatures reaching 110+☏, shattering the previous record that was in fact set in 1974 at 18 days.ĭuring this record heat wave, Phoenix also broke the record for highest daily low temperature, with 97 degrees recorded at Sky Harbor Airport. city to average more than 100 degrees F for an entire month. That’s a substantial increase for an annual average.Ĭonsider that Phoenix is set to become the first major U.S. During the previous decade, that had risen to nearly 65 degrees. For example, in the 1970s the average low temperature in Phoenix was 59 degrees F. One of the biggest problems faced by cities like Phoenix is that the nights aren’t cooling off as much as in the past. Only two of the 10 lowest temperature records in Phoenix took place within the past 100 years. The most recent of the Top 10 record lows took place in 1965. Now contrast that with annual record low temperatures in Phoenix. July 2022 had an average temperature of 95.3. The previous decade is the hottest decade on record. Phoenix is known for being hot, but this July has been distinct not just for the top temperatures, but the consistency of this heatwave. Presently, 2017 is the hottest year on record, with an average annual temperature of 77.3 degrees F. Of the 10 hottest years on record in Phoenix, nine of them have been within the past 20 years. Let’s look at the annual temperature records from the National Weather Service ( link). Matthew Earl Jones, commissioner of the Arizona Film Commission, said in a statement, Phoenix has launched some of the best and brightest producers and directors in the film industry, but we. But it’s a different story when you start looking at patterns over time. Yes, one day in 1990 stands as the all-time record. People who are confused between weather and climate may insist that it has been hotter in the past. Insider spoke with several Phoenix residents of various ages to find out what it's really like to live in the city and why people love it so much.So, that’s the first thing. The city's median age is now 34, the New York Post reported, citing the census data. In that time, it added 163,000 residents, bringing the city's population to 1.6 million. According to census data, it has seen the fastest growth of any major city in the past decade. Phoenix is now the fifth-largest city in the US, overtaking Philadelphia. has attracted relocators from coastal and Midwestern cities seeking a cheaper, more laid-back life." "Young, wealthy people are increasingly opting to put down roots in Arizona, a sign of the changing demographics that challenge the state's longstanding reputation as a haven for retirees," Insider's Natasha Solo-Lyons wrote in July. In April, CNBC reported that the trend of moving to Phoenix continued during the pandemic, citing data shared by LinkedIn and U-Haul. The migration meant that 23% of Phoenix's population was millennials. In 2019, 5,958 millennials migrated to Phoenix, according to SmartAsset, which used the most recently available US Census Bureau data. One of these cities was Phoenix, Arizona. It often indicates a user profile.Įven before the pandemic, they were leaving major cities like New York, Los Angeles, and Miami and moving to less populated cities across the US.
