rewriting history

Contrary to common beliefs, societal collapses of the past have been caused by sudden climate change, not only by social, political and economic factors, Yale anthropologist Harvey Weiss reports in a new study published in this week’s Science.

We also know where the population growth will be greatest, Weiss adds. “We must use this information to design strategies that minimize the impact of climate change on societies that are at greater risk. This will require substantial international cooperation, without which the 21st century will likely witness unprecedented social disruptions.”
