This is the final version. Available on open access from Nature Research via the DOI in this record Data availability: The peat record data that support the findings of this study can be accessed at the WDC for Geophysics, Beijing (https://doi.org/10.12197/2022GA021). High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba data from 103 high-latitude peat archives. We show that 54% of the peatlands have been drying and 32% have been wetting over this period, illustrating the complex ecohydrological dynamics of high latitude peatlands and their highly uncertain responses to a warming climate.
