Around 90 percent of New York homes have air conditioning, according to city data.<\/p>\n
On paper, that sounds like a city that has beaten the summer for good.<\/p>\n
Then a record heat wave rolled in, and when it lifted, 19 people had lost their lives to heat stress.<\/p>\n
The detail that showed up in case after case was not what most people expected.<\/p>\n
It had nothing to do with being outdoors, and nothing to do with the power grid going dark.<\/p>\n
It had everything to do with what was inside<\/strong> people’s homes, and what was not.<\/p>\n New York is not a city without cooling.<\/p>\n That near universal air conditioning felt, for generations, like the end of the story.<\/p>\n Summers conquered, danger managed, the heat reduced to a minor inconvenience.<\/p>\n But heat is now the most dangerous weather<\/strong> New York City faces, and climate change is making dangerously hot weather more frequent and intense.<\/p>\n In mid-May 2025, the city was already under its earliest heat advisory on record.<\/p>\n The machine in the window was never the whole answer.<\/p>\n Here is the part of the story that does not make the weather forecast.<\/p>\n Among those who lost their lives to heat stress and whose home cooling status could be confirmed, not one<\/strong> had a working air conditioner in use at the time, according to New York City Health Department records.<\/p>\n Owning a unit and running it are two entirely different things.<\/p>\n Not everyone can afford to run them continuously, raising the chances of heat stress and even life-threatening illness, especially for older residents and people with cardiovascular or other underlying conditions.<\/p>\n The heat does not check your energy bill before it decides to hurt you.<\/p>\n Rising electricity costs have turned a life-saving machine into a financial calculation millions of Americans make every sweltering night.<\/p>\n There is another force working against anyone trying to stay cool, and it lives in the streets themselves.<\/p>\n New York carries its own version of the urban heat island burden.<\/p>\n A 2024 Climate Central analysis found that New York City’s built environment makes temperatures an average of nearly 10 degrees Fahrenheit hotter<\/strong> for the average resident than they would otherwise be, the largest per capita urban heat island effect measured among the 65 major U.S. cities studied.<\/p>\n Some neighborhoods feel even more: parts of the city register heat indexes more than 12 degrees above what nature alone would produce.<\/p>\n Without AC, indoor temperatures can climb far higher than the temperature outside, especially at night, and can stay elevated for days after a heat wave passes.<\/p>\n The apartment does not cool down just because the sun sets.<\/p>\n The concrete and asphalt<\/strong> absorbed the heat all day and are slowly giving it back, hour by hour, through the wall and the floor.<\/p>\n Officials linked the spike in cases<\/a> to the June 2025 heat wave, and all but three were Black or Latino, with many at home without air conditioning.<\/p>\n The NYC Health Department’s<\/strong> 2026 report confirmed the pattern that had been building for years.<\/p>\n Most people who lost their lives to heat stress were exposed to dangerous temperatures in homes without air conditioning.<\/p>\n Lack of access to cooling equipment and affordable energy to operate it remains one of the most significant risk factors for heat-related harm.<\/p>\n The program meant to help run out of funding on June 5, earlier than any previous year, leaving thousands unable to access life-saving home cooling.<\/p>\n The city’s 2026 heat-related health report<\/a> makes clear this is not a crisis that appeared overnight: around 500 New Yorkers lose their lives to heat-related causes each year.<\/p>\n And the thermostat settings most people rely on were never designed for nights that simply refuse to cool down, a lesson that has played out in coastal cities chasing the same moving target.<\/p>\n The answer emerging from cities across the country is not simply more air conditioning.<\/p>\n It is rethinking the building, the block and the whole neighborhood as a living system.<\/p>\n Some architects are using passive house standards when building and retrofitting homes, prioritizing airtightness and insulation to hold a comfortable temperature without constant mechanical cooling.<\/p>\n Trees, reflective rooftops and green corridors do the same work without drawing a single watt.<\/p>\n Research on urban heat islands consistently shows that neighborhoods with little tree canopy and more heat-absorbing surfaces can run significantly hotter than greener areas just blocks away, a gap driven almost entirely by the presence or absence of shade and vegetation.<\/p>\n Extreme heat already claims more American lives each year than floods, tornadoes and hurricanes combined.<\/p>\n That is not a forecast for some distant future.<\/p>\n It is the number from last summer<\/strong>, ticking upward in cities that still believe the answer hums in a box bolted to the window.<\/p>\n The box helps. But the city around it has to change too.<\/p>\n","protected":false},"excerpt":{"rendered":" Around 90 percent of New York homes have air conditioning, according to city data.

When the AC is there but the danger isn’t gone<\/h2>\n
The city that bakes before the sun goes down<\/h2>\n
The 19, and the thing they shared<\/h2>\n
What comes after the window unit<\/h2>\n
