As heat waves swept across America last week, the Bronx bore the brunt of it.
Heatwave Havoc
Last week, temperature records were being broken across the nation. Temperatures soared to a blistering 95°F (35C) in New York, 98°F (36.6C) in Philadelphia, and a face-meltingly hot 120°F (49C) in Las Vegas. While that sounds bad enough, it may have been even worse in the Bronx.
The Bronx
The Bronx is a concrete jungle. An area of New York where the heat hits especially hard, with temperatures often feeling hotter than usual due to a combination of community poverty, inadequate healthcare, and severe air pollution.
When Home Is Too Hot to Handle
Locals found themselves seeking shelter in senior community centers, as running air conditioning at home was just too expensive. It’s a frequent issue.
Bridge Meltdown
Just a few weeks before in the Bronx it was so hot that a swing bridge connecting to Manhattan got jammed open for hours, after the metal expanded. In the end, boats had to be used to pump water on it and cool it down – a Band-Aid to a bigger issue.
The Pollution Puzzle
But that’s not even the worst of it. MIT has just come out with an eye-opening study about air pollution in the Bronx. Unlike previous research that only looked at where people live or work, this study took a more comprehensive approach.
Tracking Toxins
The researchers used mobile data to track people’s daily movements, giving a more accurate picture of real-world pollution exposure.
Pollution Exposure Worse Than We Thought
Well, once you factor in all the places Bronx residents go throughout the day, it turns out that locals are exposed to a lot more air pollution than we previously thought.
Mapping Misery
“By combining air quality data with detailed mobility patterns, we can construct accurate trajectories of people’s exposure,” said study co-author Paolo Santi to Phys.org.
A Small Number with Big Consequences
After factoring in daily travel, researchers found that exposure to harmful air particles increased by almost 2.5%.
Urban Inferno
The Bronx’s neighborhoods are lined with heat-absorbing buildings and there’s a lack of green spaces, making the summer heat even more unbearable. Many residents – particularly seniors and those more vulnerable – find that even short walks can be overwhelming in the heat.
The Fight for Cooler Communities
Community leaders have been pushing for more green spaces to help address these issues, but without funding there’s not much that can be done.
Turning City Vehicles into Data Collectors
The study, which was published in the science journal Nature Cities, used solar-powered environmental sensors mounted on police cars, fire trucks, and other public service vehicles to collect air pollution data.
Using What We Have
The study was a success in more than one way, as it proved that cities can use the infrastructure they already have to track environmental conditions effectively and cheaply.
Big Data Reveals Big Disparities
Digging deeper, the researchers analyzed anonymized phone records from 500,000 people and 500 million daily location records. They found huge differences in pollution exposure, especially among different ethnic groups.
Bronx Gasps for Air
Health problems in the Bronx are escalating because the borough has the worst air quality in the entire city.
Asthma Alley
Asthma rates have soared to 2.5 times the city average. Areas like Hunts Point and Mott Haven are struggling with a surge in emergency visits due to breathing-related issues.
Heat’s Deadly Toll
A recent city report found that around 350 New Yorkers die each year from heat-related health problems. Black residents are twice as likely to be affected compared to white residents. A major issue is that many Bronx homes lack air conditioning, making the heat even more unbearable.
Climate Change Cranks Up the Thermostat
Deadly heat waves are becoming more frequent due to climate change. But there’s hope – studies like this are helping protect city dwellers.
Tech to the Rescue
This research shows how mobile data and vehicle sensors could create widespread monitoring systems – an idea that might catch on in cities nationwide. As the climate keeps changing, these monitoring systems could be crucial for creating smart plans to protect at-risk communities.
Government’s Role in Cooling the Crisis
It’s more important than ever for the federal and local governments to focus on fixing these issues.
