How did past populations cope with climate change?
New research combining climate data, archaeology, palaeontology, geography and history shows that it did not always end in crises and societal collapse. This more realistic understanding of the past helps us prepare for the future as climate change effects intensify.
For example, researchers studied effects of climate change that began in the fifth century and lasted till the seventh on Roman-occupied Eastern Mediterranean. Pollen data and archaeological surveys show that agriculture thrived due to increased rainfall. Many settlements grew and so did economic trade between communities. Elites financed dam construction and other infrastructure allowing farmers to manage water more effectively.
The work shows how a well-organized and resourceful society adapted and exploited new opportunities.The current magnitude of climate change will require us to adapt at larger, more ambitious scales.
But as the past shows, it can be done.
