Climate and Health

Maine’s climate, like the rest of the world’s, is changing, and these changes may have a significant impact on the health of Maine people. A warming climate will lead to more frequent and extreme weather events, and may contribute to longer pollen seasons and further spread of vectorborne diseases.

Maine Center for Disease Control and Prevention receives funding from the US Centers for Disease Control and Prevention’s Climate-Ready States and Cities Initiative to identify, prepare for, and respond to public health challenges related to a changing climate. Maine CDC’s Climate and Health Unit works to identify and prevent health impacts from:

  • extreme heat and extreme cold events; Subscribe to our e-newsletter
  • pollen and other airborne allergens such as mold; and,
  • Lyme disease and other vectorborne diseases.
