PHOENIX, AZ — In a groundbreaking re-evaluation of human endurance, the City of Phoenix today announced a revised definition for "habitable urban environment," effectively recalibrating it to encompass sustained daily temperatures exceeding 120 degrees Fahrenheit. The move comes as meteorologists confirm that the city's summers are now reliably, and perhaps permanently, operating within a thermal range previously reserved for blast furnaces and the planet Mercury.

"We believe it's time to align our terminology with lived experience," stated Dr. Kendra Finch, newly appointed Chief Adaptive 2 Officer for the Greater Phoenix Resilience Initiative. "For too long, the traditional definition of 'habitable' has been a subjective and, frankly, aspirational construct. Our new framework acknowledges that if millions of people are still here, and largely functioning, then these conditions are, by empirical evidence, habitable. They're just... premium habitable." Dr. Finch noted that the city's new "Comfort Zone Re-evaluation Committee" concluded that human physiology is remarkably flexible, provided residents remain indoors, consume fluids, and limit outdoor exposure to "pre-dawn or post-apocalyptic intervals."

The rebranding effort extends to municipal services. Public pools are now referred to as "thermal relief immersion centers," and the city’s emergency cooling stations have been rebranded as "enhanced indoor recreational facilities." Critics of the new classification system were quick to point out that 'habitable' traditionally implied 'without constant threat of heatstroke,' but city officials dismissed such concerns as "outdated sentimentality." "Look, if we called 120 degrees 'unhabitable,' we'd have to empty the city," explained Mayor Rick Donovan, wiping a bead of sweat from his forehead during a press conference held in an air-conditioned bunker. "Where would everyone go? It's much more fiscally responsible to just adjust the dictionary."

Local media outlets have embraced the new paradigm, offering daily segments on "Optimizing Your Interior Existence" and "Beyond Hydration: Advanced Fluid Retention Techniques." One popular morning show featured a 10-minute segment on designing custom, climate-controlled pet habitats for animals that once roamed freely in backyards. Experts now advise residents to consider solar panels not for energy cost savings, but as a "necessary investment in continued existence, much like oxygen or, historically, water."

In an unexpected endorsement, local real estate agents lauded the redefinition, anticipating a surge in property values for homes boasting "robust indoor living infrastructure" and "minimal outdoor visibility."
