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

Key Points:

• New York City is experiencing multiple overlapping climate-related public health threats this summer, including extreme heat, wildfire smoke, flash floods, Legionnaires’ disease outbreaks, and tick-borne illnesses, all exacerbated by climate change.
• Climate change is increasing the frequency and severity of heatwaves, flooding, and vector-borne diseases, with New York expected to see up to 32 days annually over 95 degrees by mid-century and more prevalent flooding due to sea level rise.
• The city's Legionnaires’ disease outbreaks are linked to warmer, wetter conditions that favor Legionella bacteria growth, but experts emphasize these outbreaks are preventable through proper maintenance and enforcement of existing regulations.
• Public health officials face challenges responding to these compounded climate threats amid federal funding cuts, while local efforts include expanding cooling centers, increasing tree cover, and investing in flood resilience infrastructure.
• Climate justice concerns are highlighted as vulnerable populations, including Black and low-income New Yorkers, face disproportionate risks from heat and other climate hazards, leading to social isolation and health disparities during extreme weather events.
