The article discusses the most recent event on this list, the East African drought and famine that ended less than a decade ago, which resulted in 50,000 to 260,000 deaths. These climate disasters are almost always caused by too much rain or drought, which typically occur over years and sometimes as much as a decade. The number of people harmed by these events is always larger due to the larger number of deaths. Most of these events occurred more than a century ago, and in some cases a number of centuries. The most severe event on the list was the Great Famine of Europe in 1315, which killed up to 50 million people. Only one of the events occurred in America, the Dust Bowl Drought.
