What do we know for sure about climate change and its impact on the future of archeology?

Antonella Rinaldi, Florence's archeology and fine arts superintendent, said: "Tourists are welcome here but they need to respect our artworks, be they originals or replicas."

But only one group of people often harmed by archeology and anthropology, Native Americans, have a federal law that regulates this process.

Amid the relative calm that has prevailed in recent years, the country has seen a resurgence of archeology.

In northern New England, the origins of the Native American collections at the Hood Museum and the Abbe Museum in Bar Harbor, Maine, tend to be more related to anthropology and archeology, Denenberg said.
