    South American and African cratons may have been substantially modified by mantle plumes, according to analyses of seismic images and tectonic records. The results imply that cratons may not be as stable as once thought.

    Mature parts of the shallow megathrust beneath Costa Rica are characterized by striking corrugations that may channel fluids, according to seismic images. Nascent sections of the subduction zone plate boundary appear only weakly corrugated.

    The East Antarctic ice sheet may be gaining mass in the current, warming climate. The palaeoclimate record shows, however, that it has retreated during previous episodes of prolonged warmth.

    Depending on their connectivity to the river network, wetlands can be much more efficient at removing nitrate in a watershed than common nitrogen mitigation strategies according to an analysis of the Minnesota River basin.

    Land management with the aim of reducing incoming solar radiation could help with regional-scale climate adaptation and mitigation as well as ecosystem services, and avoids several shortcomings of global geoengineering.

    Earth experienced a lull in magmatic and tectonic activity about 2.3 billion years ago, followed by a flare-up of magmatism, according to a compilation of existing geologic data. These events might mark the transition to the supercontinent cycle.

    A persistent melt layer may have existed in the Archaean upper mantle, according to experimental analyses. The melt layer could have decoupled the mantle from the overlying lithosphere, hindering plate tectonics.

    The first of two stepwise increases in atmospheric oxygen occurred at the end of the Archaean eon. Analyses of sulfur and iron isotopes in pyrite reveal a near-shore environment that hosted locally oxygenated conditions in the Mesoarchaean era.

    The slowdown in surface warming in the early twenty-first century has been traced to strengthening of the Pacific trade winds. The search for the causes identifies a planetary-scale see-saw of atmosphere and ocean between the Atlantic and Pacific basins.
