Speleothems are well-known, climate-sensitive archives that can be dated with relatively high precision. Recent developments in uranium-lead geochronology have opened up new opportunities to explore palaeoclimate during periods beyond the limits of traditional uranium-thorium dating (about 600 ka). In this context, speleothems from Corchia Cave (Italy) possess exceptional qualities - high uranium, high-purity calcite - for producing palaeoclimate records back beyond 1 million years. Combining stable isotopic data from these speleothems with high-resolution records from nearby ocean cores provides new insights into the Earth?s climate system through the Middle Pleistocene Transition.
