EPA recently issued fact sheets detailing climate change impacts for each state and U.S. territory. In doing so, EPA confirmed some very basic, general findings about climate change impacts overall:

  1. Every state will become warmer.
  2. The impacts of climate change are likely to be very different from state to state.
  3. Increased rainfall intensity will cause more flooding in some states, while increasingly severe droughts may threaten water supplies in other states.
  4. Farms and forests will be less productive in some states, but warmer temperatures may extend growing seasons in others.

The fact sheets are short two page documents focused on differing issues for each state including, for example, climate change impacts related to ecosystems; air pollution and human health; the Great Lakes; agriculture; the Illinois, Ohio, and Mississippi Rivers; coastal flooding; heavy precipitation/flooding; sea level rise; and winter recreation. The fact sheet for Illinois provides good insight into the kind of information detailed.

While the new information supplements the existing climate change data available online from EPA, the information in many of the fact sheets appears dated, very general in nature, and perhaps geared to the general public. Existing climate change data associated with impacts by region and by sector is more detailed and may be more useful overall. See https://www3.epa.gov/climatechange/impacts/.
