Climate Change and Extreme Weather
How Climate Change Impacts Health
Climate change, together with other natural and human-made health stressors, influences human health and disease in numerous ways. Some existing health threats will intensify and new health threats will emerge. Not everyone is equally at risk. Important considerations include age, economic resources, and location.
In the United States, public health can be affected by disruptions of physical, biological, and ecological systems, including disturbances originating here and elsewhere. The health effects of these disruptions include increased respiratory and cardiovascular disease, injuries and premature deaths related to extreme weather events, changes in the prevalence and geographical distribution of food- and water-borne illnesses and other infectious diseases, and threats to mental health.

What You Can Do
Follow these steps to help protect yourself and your family:
- Be informed and prepared: Learn more about emergency preparedness, extreme storms and flooding, outdoor air quality, harmful blue-green algae blooms, extreme heat and extreme cold weather, and tick-borne and mosquito-borne diseases.
- Find out about how climate change affects your community: Use our Air Quality Index, Heat Vulnerability Index Maps, and Environmental Public Health Tracker.
- Use tools and resources that can help you cope with changes in temperature such as the NYS Cooling Center Finder and Cooling Assistance Benefit Program.
Responding to Climate Change
New York State works to address climate change and protect New Yorkers:
- The Climate Leadership and Community Protection Act (Climate Act), which was passed in July of 2019, is among the most ambitious climate laws in the nation. The Climate Act aims to reduce greenhouse gases from 1990 levels by 40% by 2030 and at least 85% by 2050 by increasing renewable energy use and ensuring all communities equitably benefit in the clean energy transition.
- New York State’s Extreme Heat Action Plan identifies and supports initiatives to keep residents safe and prepare communities for rising temperatures.
- New York State’s emergency preparedness programs protect New Yorkers, their property, and our economic well-being from emergencies and disasters.
