Sedimentary deposits from glacier-fed peatlands provide records of past glacier variability, but the dynamics of these peat-forming ecosystems have rarely been investigated. Through multi-proxy analyses of a 204-cm peat core, we reconstructed the ecological response of a glacier-fed peatland on subantarctic South Georgia to climate and glacier variability over the last 4300 years. A stable peatland with rapid carbon accumulations and dynamic turnovers between brown mosses and monocots persisted between 4300 and 2550 cal yr BP when the up-valley cirque glacier was small under a regional hypsithermal climate. Carbon accumulation rates showed two peak periods driven by climate warming, reaching 140 g C m−2 yr−1 at 4000–3500 cal yr BP and 70 g ...
