Discussion Prompt: Acadia National Park and other coastal and lowland parks like the Everglades National Park, Cumberland Island National Seashore, Point Reyes National Seashore, etc. are all experiencing issues of flooding and erosion with gradually rising sea level.

• How fast is sea level rising on the basis of current data?

• Why does the warming climate result in sea level rise?

• From the perspective of sustainability what should be done in these parklands to mitigate damage associated with rising seas?

• Should we as a nation just accept that some areas of these and other national parks will be underwater in 50-100 years and do nothing about it?
