  • The damming of rivers has large impacts on the balance of riverine carbon (C) processes and fluxes to the oceans. Here, the authors use decadal riverine organic C loads and model C transformations to quantify in-reservoir organic C burial, mineralization and assess decreases in riverine exports to the oceans.

  • Climate change, rising atmospheric carbon dioxide concentrations and land use change have driven a 33% increase in carbon loss from soils and vegetation to European rivers between 1901 and 2014, according to model simulations linking the terrestrial carbon cycle with river transport.

  • An analysis of regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity yields a global CO2 evasion rate of 2.1 × 1015 grams of carbon per year, which is higher than previous estimates owing to a larger contribution from streams and rivers.

  • Bottom-up and top-down approaches are used to quantify global nitrous oxide sources and sinks resulting from both natural and anthropogenic sources, revealing a 30% increase in global human-induced emissions between 1980 and 2016.

  • The Arctic Ocean is influenced by carbon and nutrients from rivers and erosion, but how this affects phytoplankton productivity is not understood. Here, the authors use a spatio-temporally resolved biogeochemical model to estimate that the input of carbon and nutrients fuels 28–51% of annual Arctic Ocean productivity.

  • Freshwater systems are important components of the carbon cycle, but the extent of their role in CO2 fluxes is poorly understood. Here Horgby and colleagues show that mountain streams are a surprisingly large source of CO2 to the atmosphere, with annual emissions that belie their spatial extent.

  • A review of current river ecosystem metabolism research quantifies the organic and inorganic carbon flux from land to global rivers and demonstrates that the carbon balance can be influenced by a changing world.

  • A substantial amount of atmospheric carbon taken up on land is transported laterally from upland terrestrial ecosystems to the ocean. A synthesis of the available literature suggests that human activities have significantly increased soil carbon inputs to inland waters, but have only slightly affected carbon delivery to the open ocean.
