{{Short description|Abrupt cold and wet period in the Holocene Epoch}} thumb|Holocene Temperature Variations The '''Piora Oscillations''' are two cold periods in the Alpine climate history of the Holocene Epoch. Its dating differs between authors and no consistent modern approach currently exists. The spatial extent of the change is unclear; moreover, it does not show up as a major, or even identifiable, event in hemispheric temperature reconstructions.{{cn|date=April 2026}}
The phenomenon is named after the ''Val Piora'' (Piora Valley) in Switzerland, where it was first detected.<ref>Lamb, pp. 124, 128, 143.</ref>
