Science magazine recently published a study which adds another substantial support to my Saharasia findings from the early 1980s. The Science study is titled "Quantifying the Influence of Climate on Human Conflict" by authors Hsiang, Burke and Migue.
Abstract: A rapidly growing body of research examines whether human conflict can be affected by climatic changes. Drawing from archaeology, criminology, economics, geography, history, political science, and psychology, we assemble and analyze the 60 most rigorous quantitative studies and document, for the first time, a remarkable convergence of results. We find strong causal evidence linking climatic events to human conflict across a range of spatial and temporal scales and across all major regions of the world. The magnitude of climate’s influence is substantial: for each 1 standard deviation (1?) change in climate toward warmer temperatures or more extreme rainfall, median estimates indicate that the frequency of interpersonal violence rises 4% and the frequency of intergroup conflict rises 14%. Because locations throughout the inhabited world are expected to warm 2 to 4 deg. by 2050, amplified rates of human conflict could represent a large and critical impact of anthropogenic climate change.
This is an interesting set of findings, though unfortunately set into the CO2 theory of global warming. My Saharasia findings, published here:
indicate, indicate the core regions of Saharasia are exceptionally hot, but also charged with atmospheric aerosols and dusts, as well as being of exceptional low humidity and carrying capacity.
This situation forces inhabitants into nomadic lifestyles, living on the marginal edge of existence. When a drought hits, they may go into famine and starvation conditions, triggering land abandonment and mass migrations, along with raiding and war against other cultures. My findings are more complex that merely that, however, but you can get the book for the details, and also visit our Saharasia page for more details and summary articles in many world languages.
The Science study did not investigate the core Saharasian desert regions, unfortunately, only some of the sub-Saharan zones.
Here’s a popular rendition of the newer findings.
Climate Change and Violence: An analysis of 60 studies finds that warmer temperatures and extreme rainfall lead to a rise in violence.
