Pequeña Edad de Hielo
Temperatures decreased for a long time after the Huaynaputina eruption in the extratropical Northern Hemisphere. Together with the 1257 Samalas eruption and the 1453 Kuwae eruption, the Huaynaputina eruption may have led to the Little Ice Age, or to the coldest period of the Little Ice Age in Europe. Arctic sea ice expansion and climatic cooling has been noted after these eruptions, and a cooling peak occurred around the time of the Huaynaputina eruption. In general, volcanic sulfate aerosol production was higher during the Little Ice Age than before or after it. In the Andes, the Little Ice Age had already begun before the 1600 eruption, although a major expansion of glaciers in the Peruvian Cordillera Blanca occurred at the time.
