Will climate change make plague-filled NYC summers like this one the new norm? - Gothamist

What the report says

Gothamist reports that New York City’s difficult summer of extreme heat, wildfire smoke, flash flood warnings, a deadly Legionnaires’ disease outbreak and rising tick-borne illnesses reflects a broader public health challenge being intensified by climate change. The article, published July 27, says policy and health experts expect overlapping climate-related hazards to become more common as the city grows hotter and wetter.

The report cites city climate chief Louise Yeung, who said New Yorkers are increasingly facing multiple climate threats at once. Gothamist notes that the city has been reclassified in recent years as having a subtropical climate, and cites the New York State Climate Impacts Assessment projection that days above 95 degrees could rise substantially by midcentury. Yeung also emphasized that risks are unevenly distributed, including greater heat mortality risk for Black New Yorkers and added burdens for lower-income residents who may struggle with cooling costs.

Legionnaires’ disease is a major focus of the report. Experts told Gothamist that warmer, wetter and more humid conditions can raise the risk of the bacteria that cause the illness, including in cooling towers and plumbing systems. But Legionnaires’ specialist Janet Stout said outbreaks linked to cooling towers can be prevented through maintenance and stronger enforcement of existing rules. Some City Council members are also proposing a summer hotline for public questions about Legionnaires’.

Gothamist also reports that experts have not tied this summer’s cyclosporiasis outbreaks to climate change, while noting that flooding and other extreme weather can increase food contamination risks. The article places these concerns against a backdrop of federal cuts to public health and climate work, while describing city efforts including cooling centers, mosquito control, building emissions rules, tree cover plans, coastal resilience projects and hyperlocal monitoring by community groups.
