Editorโs note: This is the second story in a four-part series on Code Red heat in Baltimore by the University of Marylandโs Capital News Service and the Howard Center for Investigative Journalism. A longer version is available to read on the Code Red project website.
BALTIMORE, MarylandโHeat radiates from the asphalt and concrete that cover the streets, the sidewalks, the alleys, even the tiny yards behind the homes in the East Baltimore neighborhood of McElderry Park. Trees are scarce. And air doesnโt move much when it comes up against block after block of rowhouses.
So as a dangerous 11-day heat wave tormented the city in July, the hottest month ever recorded on the planet, fewer and fewer residents were going outside.
โCanโt even put your head out the door,โ said Tammy Jackson, 48, on a day when the temperature outside hit 100 degrees Fahrenheit and 92 degrees in her home. โThis is too much. Oh Lord, this is too much.โ
But it is going to get worse. In McElderry Park and around the world, in communities rich and poor, downtown and in the suburbs, weather disasters loom. And experts are using language ever more dire.
Average annual temperatures in Baltimore have gone up more than 3 degrees over the last century, nearly twice as much as the rest of the country.
More and more people, including Del. Robbyn Lewis, who represents parts of East Baltimore, are replacing the words โclimate changeโ with stronger language.
โWe are,โ she said, โin an emergency.โ
Cities, crowded and paved-over, already feel the impact, with poorer air quality and streets, highways and bridges damaged by storms. But certain neighborhoods will continue to feel the effects of extreme temperatures more than others.
Researchers at Portland State University in Oregon and the Science Museum of Virginia have mapped these areas, called urban heat islands, and data shows that temperatures here and in surrounding neighborhoods can run 8 degrees hotter than in communities that have more trees and less pavement. McElderry Park, which despite its lyrical name offers little green space, is one of these.
Residents in the hottest areas have higher rates of chronic illnesses affected by heat, including asthma and COPD. In hot weather, emergency medical calls for some chronic conditions increase. The rate of emergency medical calls for cardiac arrest and congestive heart failure, for example, nearly double when the heat index hits 103 degrees.
Households in the cityโs hottest areas are poorer, which means the residents donโt have the resources to move out.
This is true across the country. In a majority of the countryโs most populous cities, people with lower incomes typically lived in the hottest areas, an investigation by journalists from NPR and the University of Maryland found.
Sacoby Wilson, a professor at the University of Maryland School of Public Health, says people in low-income neighborhoods walk more, ride more buses and drive fewer cars, so they contribute less to climate change. And yet they are more vulnerable to dying in extreme heat.
โEnvironmental justice and climate change,โ Wilson said, โare inextricably linked.โ
Rowhouses, Baltimoreโs signature architecture, trap heat and stay hot even when the weather cools on summer nights. Crime rates are higher, so many people wonโt put an air-conditioning unit in a first-floor window for fear of break-ins.
The problems are not new. Many stem from historical segregationist zoning and lending policies that for decades limited where black citizens could live.
During an 11-day July heat wave, Baltimoreโs health department put out press releases advising citizens to drink water, cut back on outdoor activities and find relief in designated air-conditioned cooling centers.
Inside the rowhouses, even those with an air-conditioning window unit, the heat simmered.
Reporters from the University of Marylandโs Howard Center for Investigative Journalism and Capital News Service placed sensors that record heat and humidity inside several homes in McElderry Park and nearby neighborhoods. Those sensors recorded temperatures that reached as high as 97 degrees and heat index values of 119 degrees.
In some houses, those readings showed that it was hotter inside than outside.
At 7 p.m. Friday, the heat index in Baltimore hit 103 degrees. Inside the bedroom Stephanie Pingleyโs niece shares with one of Pingleyโs three sons, it was 13 degrees hotter, with a heat index of 116 degrees. All of her boys have asthma.
By Saturday, the heat index inside the second-floor apartment of Michael Thomas and Alberta Wilkerson hit 112 degrees. A fan pushed hot air around. Thomas, 61, has emphysema. Wilkerson, 49, has had a heart attack.
โJust living through it,โ Thomas said.

On Sunday, Solomon Simmons, who is retired from a job at the Johns Hopkins Bayview Medical Center, went to Hope Community Church, where he is a deacon. โWe had trouble getting the church cool,โ he said.
Simmons, 71, will not put an air-conditioning unit in a first-floor window facing the street โbecause of security.โ But especially for children, older residents and people coping with chronic diseases, air conditioning is the answer.
Tammy Jackson, who has asthma, said she had to stop cooking dinner one July evening when the heat made it hard for her to breathe. The next day, she told her husband, โBaby, I canโt cook until I get AC.โ
Twenty people have died of heat-related illnesses in Maryland so far this year, three of them in Baltimore, according to data through Aug. 28.
Historically, the Baltimore area has averaged about six days a year when the heat index exceeded 100 degrees, according to new research from the Union of Concerned Scientists and the University of Idaho.
If no action is taken to reduce carbon emissions, by mid-century that figure will rise to more than 37 days annually, according to the researchers.
As temperatures in Baltimore reached 100 on July 20, most everyone around the city was staying inside. โThis is the quietest the block ever been,โ Tammy Jackson said. โI canโt believe it.โ
But city life continued despite the heat. A team of paramedics was called to an East Baltimore block when a resident found a man she didnโt know passed out on her front steps.
The paramedics revived the man, who apparently had overdosed, with a dose of Narcan. He stood up and wandered off, rejecting advice to go to the hospital.
NPR reporters Meg Anderson, Nora Eckert and Sean McMinn and University of Maryland reporters Jake Gluck, Jane Gerard, Roxanne Ready, Theresa Diffendal and Sean Mussenden contributed to this story.
