Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It decimated agriculture, killed as much as 15 percent of the population and sparked a fatal attempt to establish a Scottish colony in southern Panama. The researchers say the episode—shown in their study to have been during the coldest decade of the past 750 years—was probably caused by faraway volcanic eruptions. But it was not just bad weather that brought disaster. Among other things, Scotland was politically isolated from England, its bigger, more prosperous neighbor that might have otherwise helped. Propelled in part by the catastrophe, the two nations merged in 1707 to become part of what is now the United Kingdom. Such a famine-related tragedy was never repeated, despite later climate swings.
