Short summary

We use stalagmites to study past changes in the terrestrial P cycle. Our P records from multiple, coeval stalagmites from Northwest Spain show that the onsets of past abrupt cooling events are characterized by multi-century reproducible peaks in stalagmite P which reflect higher groundwater P/Ca concentrations and enhanced P export, potentially resulting from increased freeze-thaw frequency and more intense infiltration from snowmelt.
