There is evidence that hot climatic temperatures and crime are linked. With climate change raising temperatures around the world, it is possible we may see higher levels of personal aggression. Based on data from Russia, this column shows that on hotter days, women are more likely to be killed in homicides, especially over weekends. Colder days have no similar effect on violence. Lower wages and higher unemployment contribute to higher homicide rates, so policies promoting employment may mitigate victimisation during extreme temperature days.

Studies have found that the occurrence of natural resources can increase the risk of civil war and interstate conflict. This column uses data from 50 countries beginning in 1890 to show that silver mining can also have substantial effects on interpersonal violence during peacetime. Across many different countries and periods, an economy's increasing dependence on silver has increased the homicide rate.

Local economic shocks induced by the Brazilian trade liberalisation had substantial effects on homicides. This column examines these effects and attempts to disentangle the mechanisms through which they occurred. Reductions in employment rates appear to have been the main driving force.
