Ice shelves modulate Antarctica's contributions to sea-level rise. Regional-climate-model simulations and observations suggest historical ice melt intensification before collapse of Antarctic peninsula shelves, and project future melt evolution. The image shows the ice shelf edge off Antarctica.

    The International Year of Soils draws attention to our vital dependence on the fertile crumb beneath our feet. Soil is renewable, but it takes careful stewardship to keep it healthy and plentiful.

    Delivery of palatable 2 °C mitigation scenarios depends on speculative negative emissions or changing the past. Scientists must make their assumptions transparent and defensible, however politically uncomfortable the conclusions.

    Plate tectonics is the surface expression of mantle convection. Seismic observations at the Cascadia subduction zone show that coupling between tectonic plate motion and mantle flow may depend on the size of the plate.

    Compared to Earth, the Moon is depleted in volatile species like water, sodium and potassium. Simulations suggest that much of the Moon formed from hot, volatile-poor melt in a disk of debris after initially amassing cooler, volatile-rich melt.

    The last glacial period and deglaciation were marked by abrupt, millennial-scale climate changes. Changes in the North Atlantic meridional overturning circulation were important contributors to rapid climate variability, but did not act alone.

    Oxygen minimum zones exert important controls over ocean biogeochemistry. Lagrangian modelling demonstrates that the mean positions of mesoscale eddies delimit the boundaries of the Peruvian oxygen minimum zone.

    The last deglaciation was interrupted by a cool period known as the Younger Dryas. Numerical simulations suggest that the cold interval was the result of a combination of changes in ocean and atmospheric circulation and reduced radiative forcing.

    Subduction carries water into the Earth where it can influence seismicity. Analysis of the structure of the Alaskan subduction zone suggests fluid delivery is influenced by faults in the oceanic plate that formed at the mid-ocean ridge.

    Shallow mantle flow could be induced by the motions of overriding tectonic plates or by deeper mantle convection. Analysis of mantle flow patterns in the Pacific Northwest shows that flow aligns with the motions of the largest oceanic plates.

    The width of the tropical belt affects the subtropical dry zones and has expanded since 1980. Analyses of observations and climate–chemistry model simulations suggest that the northern tropical edge retracted between 1945 and 1980.
