While we may think of climate change as being a somewhat recent phenomenon, it is in fact something that humans have battled for centuries.
The Roman Empire, for example, unraveled during a spasm of volcanic explosions, which led to a period of cooling that precipitated the first pandemic of bubonic plague. The decline of the ancient Maya in Central America has been linked with a major drought. Angkor Wat’s downfall, in modern-day Cambodia, has been pinned on a period of wild swings between drought and monsoon floods. So if minor forms of climate change spelled the collapse of these great societies, how are we supposed to survive the much more radical shifts of today?
New research suggests that resilience is an ability that societies can gain and lose over time. Researchers found that a stable society can withstand even a dramatic climate shock, whereas a small shock can lead to chaos in a vulnerable one.
There are a number of ways that societies adapted to a changing environment across millennia: Migration allows people to move to more fruitful landscapes; flexible governments learn from past disasters and adopt policies to prevent the same thing from happening again; establishing trade networks makes communities less sensitive to changes in temperature or precipitation. Societies that have greater socioeconomic equality, or that at least provide support for their poorest people, are also more resilient.
