As the world confronts escalating climate disasters, archaeologists say ancient history can reveal what it takes to survive.

• Post Reports

As California works through the devastating consequences of catastrophic flooding, today on “Post Reports” we look back at another climate disaster and ask if survivors can find healing on the very land that holds the scars of climate change.
