Summer Challenges Faced by New Yorkers

New York City is grappling with extreme heat and the smoke from wildfires, alongside flash flood warnings and another serious outbreak of Legionnaires’ disease. Plus, tick-borne illnesses are on the rise. This summer certainly feels plagued, and it seems many feel the same way.

Experts say climate change is making these public health issues worse, and encountering multiple climate-related health risks simultaneously is likely to become the norm.

Though climate change hasn’t been directly linked to the recent surge in foodborne illnesses, including severe gastrointestinal issues, specialists warn that the drastic weather changes may lead to an increased frequency of such outbreaks.

These accumulating climate-related health threats are putting extra strain on public health departments, particularly as there are budget cuts coming from the federal level affecting climate and health initiatives.

“New Yorkers are no longer facing just one type of weather event,” explained Louise Yeung, the city’s chief climate officer. “We’re now in a hotter, wetter climate, and we’re encountering many climate-related challenges simultaneously.”

Yeung pointed out the unequal effects of climate change, noting that certain groups, such as Black New Yorkers, are more vulnerable to extreme heat. Those with lower incomes often can’t afford the costs associated with using air conditioning.

In recent years, New York City has been categorized as having a subtropical climate, with milder winters and hot, humid summers becoming more pronounced.

By the mid-21st century, the city could see between 14 and 32 days a year with temperatures surpassing 95 degrees, a significant increase from about four days historically. Flooding is also expected to become more frequent because of increased precipitation and rising sea levels.

Dr. Ashish Jha from Harvard’s Belfar Center pointed out that climate change is also increasing the threat of “vector-borne” diseases, transmitted to humans through organisms like ticks and mosquitoes.

This summer, Dr. Alister Martin, the city’s health commissioner, has frequently referenced climate change as a contributor to the higher risk of Legionnaires’ disease outbreaks, acknowledging it as an evolving seasonal challenge.

Some city council members are suggesting that the health department set up a hotline dedicated to Legionnaires’ disease to address public concerns more effectively.

Legionnaires’ expert Janet Stout noted that while climate change is indeed making this illness more common, it doesn’t mean that residents should accept annual summer outbreaks as an inevitable reality.

Legionella bacteria thrives in warm water, such as that found in New York’s cooling towers. Research indicates that since the early 2000s, higher temperatures and increased rainfall have heightened the risks of Legionnaires’ disease in the Northeast.

Stout believes that outbreaks linked to cooling towers are preventable through better maintenance and oversight of these systems, suggesting that the city may need to enforce existing regulations more strictly.

A spokesperson for the city health department, Chantal Gomez, mentioned that the agency has managed to respond effectively to the interlinked issues of Legionnaires’ disease and extreme heat this summer. This adaptability has been aided by emergency protocols established before major events like the World Cup.

Gomez added that actions such as treating areas for mosquitoes to prevent West Nile Virus have become routine to protect New Yorkers against climate-related threats.

Still, experts caution that just because climate change affects public health doesn’t mean it’s responsible for every issue. For instance, the ongoing foodborne illness outbreaks currently causing severe gastrointestinal symptoms haven’t been proven to be connected to climate change.

However, food safety experts argue that climate change could lead to more foodborne illnesses due to things like flooding, which can overwhelm sewage systems and contaminate crops.

Erika Austhof, an assistant research professor studying foodborne diseases and climate change, commented on the cuts to foodborne illness surveillance systems that hinder tracking and understanding these emerging themes over time.

Looking Toward the Future

Yeung explained that the current administration has a dual focus: protecting people from immediate climate threats, such as providing more cooling centers during heatwaves, and implementing infrastructure and policy changes to combat the root causes of climate change.

Part of the long-term strategy includes ensuring compliance with new regulations aimed at reducing greenhouse gas emissions, as well as plans to increase tree coverage in upcoming decades.

Mayor Zohran Mamdani recently announced more funding for the Bureau of Coastal Resilience, which is tasked with creating flood protection systems in Lower Manhattan.

Valentina Rojas, an environmental health manager at We Act for Environmental Justice, emphasized that community efforts at a local level can empower New Yorkers to tackle climate change challenges effectively.

In addition to pushing for supportive policies—like new laws requiring landlords to provide air conditioning in certain apartments—her group is working on gathering data regarding the localized impacts of climate change.

One initiative involves placing air quality monitors in Upper Manhattan and indoor temperature monitors in Harlem residences. Rojas shared that many participants from the project have reported that climate change is diminishing their quality of summer experiences.

“Many of the older participants I spoke with feel isolated during the summer because they have to stay indoors,” she said. “To safeguard their well-being, they turn on the AC, reduce electricity use to manage costs, and miss out on outdoor interactions. It’s a truly isolating experience now.”

The prior summer was particularly difficult, highlighted by a Legionnaires’ outbreak in Harlem that ultimately claimed seven lives.

“People were scared to step outside,” Rojas recounted.

Is this the new reality for NYC summers—sitting alone in one’s apartment? Rojas’ response was optimistic: “No. Reach out to your neighbors. If you find yourself at home, try to connect with someone nearby to see how they’re doing.”
