    Weathering everywhere? Exploring water pathways from a very steep mountain catchment to upland hills

    Climate change will lead to a change in rainfall intensity and quantity in both extreme environments and the more mundane, with consequences for flooding and landscape erosion. Rainfall leads to run-off, which transports sediments, rocks, trees, and debris as the intensity of the run-off increases. A geomorphologist, or someone like me, might assume that surface run-off is the key processes required to understand the risk of erosion and transport of debris.

    In-scaling measurements of the hydro- and cryosphere

    Whether collecting field data or running computer-based simulations, effectively measuring environmental processes across spatial and temporal scales has posed a persistent challenge for researchers. These challenges are particularly acute with regard to the hydro- and cryosphere, where fluxes of water can vary significantly across time and space. Emerging technologies and integrated methodological approaches provide a path forward to effectively scale measurements of the hydro and cryosphere, yielding better data that inform process-based discovery and scientific insights.

    New developments for paleoclimate studies

    Lake sediments are useful to track a history of long-term environmental changes.  Environmental monitoring often extends back no more than a few decades, and is largely non-existent in remote places like the Arctic, which is currently experiencing some of the most rapid environmental change on Earth. Archival sediment records in the form of dated sediment cores can greatly enhance our knowledge of past environmental change because they can extend the time scales of studies by thousands of years and they are broadly distributed in the environment.
