Climate forcing is a key variable in Earth Surface Dynamics and drives erosion processes and topographic evolution in various environmental contexts. Understanding the geomorphic response to (1) anthropogenic climate and land-use change, (2) high-frequency climate variability (e.g. freeze-thaw cycles, monsoonal precipitation), (3) extreme climatic events (e.g. tropical cyclones, flood/debris flow events), and (4) long-term climate trends (e.g. Plio-Pleistocene glacial/interglacial cycles, Late-Pleistocene to Holocene climatic change) appears of prime importance to better interpret erosional processes and sediment/element fluxes at the Earth’s surface.

This session aims at presenting studies addressing climatically-induced changes in surface processes, sediment production and the evolution of topography, as well as feedbacks between climate and Earth Surface Dynamics over different temporal and spatial scales. Feedbacks could emerge, for example, from a dependence of erosion rates on frequency and amplitude of climate change, lithospheric loading by accumulation of ice or unloading by deglaciation or erosion, and ultimately by coupling tectonics and climate.

We welcome contributions including (but not limited to) field investigations, remote-sensing, morphometric analyses, numerical modelling, geochemical tracers, sedimentary archives or other innovative tools.
