Your Essential Guide to Thriving in a Changing Climate: A Blueprint for Adaptation

How does climate change influence human organization and evolution? An international team of researchers, including those from the Université de Montréal, believes that archaeology holds the answers. They argue that investigating past societies can illuminate how climate shifts shape human experiences.

In their paper in *Nature Communications*, the scientists highlight how cultural systems are often overlooked in the climate science models we use today. They propose merging insights from climate studies and evolutionary anthropology to better understand how environmental changes affect human societies.

According to their research, transformations in landscapes due to climate change can alter demographics, disrupt social networks, and trigger cultural shifts. Led by anthropologist Ariane Burke, the team comprises nine experts in archaeology, anthropology, geography, and Earth sciences across the U.S., the U.K., Germany, and France.

Burke explains that they are developing a framework for models that include human systems. “We analyze environmental and archaeological data to create habitat suitability models. These models outline how human groups once interacted with their environment,” she says. By applying cultural evolution theory, they can predict cultural changes and test these predictions against archaeological evidence. This helps them explore how ancient climate changes influenced cultural evolution.

Historically, human societies have adapted to climate change with varying degrees of success. For instance, after the last ice age over 10,000 years ago, certain cultures thrived by altering their resource use and agricultural practices. The archaeology of climate change is a growing field dedicated to understanding these past interactions.

Burke’s team aims to identify moments in climate history that triggered significant societal reorganizations. They emphasize that cultural diversity, which helped humans adapt in the past, could be key to facing current challenges posed by global warming. Interestingly, recent studies have shown that societies that embrace diverse practices often demonstrate greater resilience to environmental changes.

As climate change continues to reshape our planet, examining how our ancestors responded offers valuable insights. These lessons can guide modern communities in developing strategies to combat current and future environmental changes.
