Expert credibility in climate change pdf10/4/2023 The sustained high temperatures prevent people from getting relief when their bodies desperately need it. "That tends to be actually kind of a good thing for our energy needs in the wintertime, but in the summertime … when it's on our hottest days with the brightest sunshine, the least amount of wind and the least amount of cloud cover, these conditions tend to become the recipe for these extreme temperature difference to become the most stark." Yvette Johnson, 54, sits next to a fan outside her family's home in Houston on June 10, 2022, when Texas was under a heat wave alert.īen Zaitchik, a professor of earth and planetary sciences at Johns Hopkins University, told CBS News that urban heat lingers, and is usually maximized, at night. "Urban areas tend to be several degrees warmer than their outlying rural areas throughout the year," Hoffman said. The phenomenon isn't confined to summer heat waves. In his own research in Richmond, Hoffman's team found a 16 degree Fahrenheit difference between the coolest and warmest places - less than 3 miles apart - at the exact same time during a heat wave. "Within a city, just because there's a heat wave going on, no one's experiencing that the same exact way everywhere," Jeremy Hoffman, an environmental science professor and scientist at the Science Museum of Virginia, told CBS News. cities - including Yoon's in New York City - have been tracking temperatures to show the impact of excessive heat and the heat island effect.Ī map of their findings in New York shows how by the afternoon and evening, the heat index is substantially higher in the neighborhoods of Washington Heights, Harlem and the South Bronx when compared to the Upper East Side, Central Park and the Upper West Side. Yoon, the heat island researcher, is part of a project participating in a nationwide campaign by the National Oceanic and Atmospheric Administration to "make heat visible." Teams in various U.S. "So, it's a lot of people experiencing it." "Today, there are over 200 to 250 million people that experience temperatures of over 35✬ every summer, living in about 318 urban areas" across the U.S., environmental scientist and climate resilience specialist Deborah Brosnan said. On Tuesday and Wednesday, the National Weather Service expects Phoenix will smash two more records, blowing past the daily record highs for those days. It's partially to blame for the triple-digit temperatures that have plagued the city every single day in July – a problem that's expected to persist through at least the end of the month. Phoenix, Arizona, is also a city that experiences this effect. population currently lives in metro areas, and the heat island effect is felt most intensely in New Orleans, New York City, Houston, San Francisco and Newark, New Jersey, according to a 2021 report by the nonprofit Climate Central. Pretty much every metropolitan area experiences this effect to some degree.
