Just how hot it gets depends not only on the weather, but also on infrastructure, working conditions and ZIP codes.\u00a0<\/p>\n<p>When that heat bears down on cities, with all their steel-and-concrete infrastructure, it can create what scientists call an \u201curban heat island.\u201d\u00a0<\/p>\n<p>Under this phenomenon, concrete structures and roads can essentially act like \u201cheat batteries,\u201d where man-made surfaces absorb and emit more heat than natural landscapes, like grass or trees, leading to elevated temperatures, said Luis Ortiz, an assistant professor in the department of atmospheric, oceanic and earth sciences at George Mason University, and a member of the New York City Panel on Climate Change, an advisory body that helps inform policy on climate issues.\u00a0<\/p>\n<p>Other factors contribute too\u2014machinery like air conditioners eject heat into the atmosphere, and tall buildings block cool gusts of wind.\u00a0<\/p>\n<p>Temperatures can vary across big cities like New York and Houston, depending on the landscape and the amount of green space and trees in a given neighborhood. Local scientists and community organizations have worked to understand the urban heat island effect over the past few decades. But the average city resident doesn\u2019t always know that their neighborhood may feel hotter than the temperature from weather forecasts.<\/p>\n<p>Scorching Cities<\/p>\n<p>Around 150 Houston residents attached temperature sensors to the windows of their cars and drove around the city in 2024 to document the urban heat island effect in real time. This was the second study of its kind for the Houston Advanced Research Center; the first happened in 2020.\u00a0<\/p>\n<p>As expected, the results showed that areas with denser development and less tree cover were hotter. For many volunteers, it offered a snapshot of a problem that they can feel the effects of, but may not always be able to prove. It was not just about the science, said Meredith Jennings, the director of local government and community initiatives at the Houston Advanced Research Center, who worked on both experiments.\u00a0<\/p>\n<p>\u201cFor people to participate in this campaign and talk about it on the news and see how heat impacts people differently,\u201d she said. \u201cThat can inform how people take action.\u201d\u00a0<\/p>\n<p>From 2016 to 2024, the National Oceanic and Atmospheric Administration, in partnership with other federal agencies, <a href=\"https:\/\/www.noaa.gov\/news-release\/federal-agencies-communities-to-map-heat-inequities-in-14-us-cities\" rel=\"nofollow noopener\" target=\"_blank\">funded<\/a> the mapping of the urban heat island effect in American cities, including Houston. The U.S. Department of Agriculture <a href=\"https:\/\/harcresearch.org\/news\/harc-awarded-15-million-from-usda-to-increase-tree-canopy-in-underserved-communities-in-houston-and-harris-county\/\" rel=\"nofollow noopener\" target=\"_blank\">funded<\/a> the second study through a program to increase tree canopy in underserved communities. With recent federal cutbacks on climate research, the future of mapping heat and cooling in cities may now rest more firmly on the shoulders of local leaders.\u00a0<\/p>\n<p>In many cities across the country, you are more likely to live in a hotter neighborhood if you are <a href=\"https:\/\/www.nature.com\/articles\/d41586-023-02618-1#:~:text=%E2%80%9CIt%27s%20environmental%20racism.%E2%80%9D%20Busy,becoming%20a%20more%20urgent%20matter.\" rel=\"nofollow noopener\" target=\"_blank\">low income or a person of color<\/a>.<\/p>\n<p>Communities in neighborhoods with very little green space have also often suffered because of their proximity to industry, such as power plants\u2014which release heat while operating\u2014and highways. A recent study found that highway expansions can considerably <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0264275125008583\" rel=\"nofollow noopener\" target=\"_blank\">worsen the heat island effect<\/a>.\u00a0\u00a0<\/p>\n<p>In hotter neighborhoods, air conditioners are often used more frequently. <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378778819326696?via%3Dihub\" rel=\"nofollow noopener\" target=\"_blank\">Research<\/a> has linked buildings\u2019 higher cooling energy demand to urban overheating\u2014and that\u2019s if the resident even owns an air conditioner and can afford to use it amid rising electricity costs.\u00a0<\/p>\n<p>According to New York City <a href=\"https:\/\/a816-dohbesp.nyc.gov\/IndicatorPublic\/data-features\/heat-report\/\" rel=\"nofollow noopener\" target=\"_blank\">data<\/a>, Black New Yorkers are twice as likely to die from heatstroke, with death rates twice that of white residents. They are also less likely to operate an air conditioner. The city\u2019s panel on climate change has predicted that the number of hot days and nights will <a href=\"https:\/\/nyaspubs.onlinelibrary.wiley.com\/doi\/10.1111\/nyas.15180\" rel=\"nofollow noopener\" target=\"_blank\">increase<\/a> between 15 and 52 days by midcentury.\u00a0<\/p>\n<p>Overheating and heat-exposure illnesses, such as sunstroke, can be very taxing on the human body, Ortiz said. Informing the public, especially outdoor workers, about heat-related health risks is crucial, he said. My colleagues Keerti Gopal and Martha Psowski <a href=\"https:\/\/insideclimatenews.org\/news\/24112025\/texas-worker-heat-deaths\/\" rel=\"nofollow noopener\" target=\"_blank\">have written<\/a> about the threat that heat exposure poses to Texas construction workers.\u00a0<\/p>\n<p>But that\u2019s not to say that cities are always more dangerous than rural areas during periods of extreme heat. Ortiz pointed out that in New York, for example, the dense buildout means that help in the form of cooling centers\u2014air-conditioned rooms that local officials open up to the vulnerable public on very hot days\u2014or even just a cool store or library, can be more readily available than in a suburban or rural environment.<\/p>\n<p>Cooling Down<\/p>\n<p>Climate change is making our summers warmer, and this summer <a href=\"https:\/\/www.npr.org\/2026\/03\/12\/nx-s1-5745008\/el-nino-summer-2026-forecast-hot\" rel=\"nofollow noopener\" target=\"_blank\">seems poised to continue that trend<\/a>.<\/p>\n<p>City governments that want to cool down hot neighborhoods can take practical steps like adding green spaces and street trees as well as using roof and pavement materials designed to absorb less heat.\u00a0<\/p>\n<p>Although planting trees is a <a href=\"https:\/\/www.nature.com\/articles\/s41598-024-51921-y\" rel=\"nofollow noopener\" target=\"_blank\">proven<\/a> way to cool neighborhoods by providing shade and lowering air temperatures, maintaining street trees can be costly, especially when<a href=\"https:\/\/gothamist.com\/news\/drought-presents-dire-threat-to-nycs-street-trees-arborists-say\" rel=\"nofollow noopener\" target=\"_blank\"> they are dying<\/a> from drought.\u00a0<\/p>\n<p>In New York, the city\u2019s forthcoming <a href=\"https:\/\/www.urbanforestplan.nyc\/\" rel=\"nofollow noopener\" target=\"_blank\">Urban Forest Plan<\/a> will be designed to cover 30 percent of the city with tree canopy, in part to reduce heat in certain areas. I <a href=\"https:\/\/insideclimatenews.org\/news\/13122025\/new-york-city-forest-restoration-grants\/\" rel=\"nofollow noopener\" target=\"_blank\">reported in December<\/a> that the city received state funding to plant and care for trees in its ailing forests.

According to <a href=\"https:\/\/www.houstontx.gov\/mayor\/Resilient-Houston-20200518-single-page.pdf\" rel=\"nofollow noopener\" target=\"_blank\">the plan<\/a>, city residents are forecast to experience 74 days a year with a heat index\u2014a measure that assesses how a mix of heat and humidity feels to the human body\u2014of 105 or more by 2050. Currently, they experience an average of only 10.\u00a0<\/p>\n<p>\u201cClimate projections and the historical trends\u2014they\u2019re all pointing toward summers becoming more and more unbearable and longer,\u201d Jennings said. \u201cSo this really becomes a quality of life issue.\u201d<\/p>\n<p>More Top Climate News<\/p>\n<p>Wildfires have destroyed grasslands across Nebraska, culminating in the loss of over a million acres, <a href=\"https:\/\/www.theguardian.com\/world\/2026\/apr\/14\/wildfire-cattle-ranchers-american-great-plains\" rel=\"nofollow noopener\" target=\"_blank\">reports Gabrielle Canon for The Guardian<\/a>.
