A network of interdisciplinary scholars studying past climate change
Another study, published in the latest issue of PNAS has found a modest but statistically significant correlation between climate and conflict in Africa since 1990. In particular, the authors find that especially high rainfall correlates with reduced conflict and especially high temperatures correlate with elevated conflict. The results fit with a growing list of studies fitting past climate anomalies with war and violence (even though most of these studies only consider linear correlations rather than thresholds, consider temperature and precipitation separately rather than as drought indices, and neglect the duration and seasonality of anomalies). This one has picked up a little coverage in the press, too.
