Abstract

Significance: We examine the link between extreme weather events and interstate conflict using data covering the three ancient kingdoms on the Korean Peninsula over seven centuries. Extreme weather events, such as drought and heavy rainfall, have a direct causal effect on conflict, but this effect is asymmetric: Shocks are far more likely to give rise to opportunistic invasions (where the state experiencing the shock is attacked) than to desperate invasions (where the state experiencing the shock initiates attack). We identify food insecurity as a critical source of vulnerability. Since climate change is leading to increased frequency of extreme weather events, a better understanding of the implications for labor-intensive armed conflict can help with mitigation strategies.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Climate-induced food shortages increased the risk of conflict when climate variation undermined agricultural production in agriculture-dominated societies and economies.

    “For example, Zhang et al (2007) and Jun and Sethi (2021) showed that climate-induced food shortages increased the risk of conflict when climate variation undermined agricultural production in agriculture-dominated societies and economies.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
