Last week we discussed how Native American sites are at risk of being damaged or lost completely due to sea level rise and climate change. Climate change is affecting all of our cultural resources in one way or another, and Florida is especially vulnerable. According to NOAA, the ocean is eight inches higher than it was in 1950, and it could rise up to another eight inches in the next twenty years. That is a significant rate increase in sea level rise!
Higher sea levels bring with it more intense storm surge that pushes farther inland. It also increases the occurrence of nuisance flooding, such as King Tides (which occur more frequently now in South Florida). We are already seeing the effects of climate change in Florida. One of the complications with sea level rise is that different areas will see different impacts. A great tool for exploring how sea level rise will impact different geographic areas is the NOAA Sea Level Rise Viewer
Today, almost 40% of the U.S. population lives in coastal areas that may be vulnerable to sea level rise. Coastal areas have always provided resources and been good places to live. This is true now and was also true for some of Florida’s earliest inhabitants. These early inhabitants left behind evidence of their culture and life, which now exist as archaeological sites. The Florida Master Site File data shows that over 16,000 cultural resources in Florida will be at risk with a one meter rise in sea level. With a two meter rise this number bumps up to over 34,000 cultural sites at risk. This is not an insignificant number. What can we do? We cannot move archaeological sites and it is impractical for a variety of reasons to excavate the entire site. And we cannot stop sea level rise in order to save these sites (although let’s hope we can perhaps curb the rate at which it is rising).
Gathering data is a good course of action. We cannot tackle an issue if we do not define the problem.
Gathering data on archaeological sites helps us with understanding exactly how these sites are being affected by sea level rise. Baseline data can help us determine the rate at which these sites are being damaged and how. It can also help us in establishing techniques to stabilize and protect these sites. Of course, there are many more sites than there archaeologists and we are racing against the clock. This is where volunteers come in! And yes, you can help!

site along Florida's coastline.
The Florida Public Archaeology Network has a statewide public engagement program to help get the public involved in documenting and monitoring archaeological sites that are in danger due to climate change and sea level rise. Heritage Monitoring Scouts (HMS Florida) is designed to have volunteers track changes to archaeological sites that are at risk. Scouts will receive monthly updates on training and resources that are available to them and will gain access to a database where they can document their findings systematically. This is a statewide program and anyone can participate, even children with adult supervision. Signing up as a Scout is a great way to get outdoors to explore and do some good too! If you would like more information or have questions about what sites are available to monitor in your area, contact your regional FPAN office.
