Climate & Health

Climate change is an ongoing shift in the earth’s normal temperatures, rainfall, precipitation, and storm intensity and pattern. These weather changes in our Earth’s climate affect our health, the environment, and our economy. While there are natural causes, human activity is making climate change worse. This is because of energy consumption releases billions of tons of carbon dioxide (CO2) and other greenhouse gases into the atmosphere every year.

The New Orleans Health Department works collaboratively with the Louisiana Department of Health and other local and state partners to support the development of climate and health-focused data sharing and initiatives.
