    It is not clear how the public views the acceptability of bioenergy with carbon capture and storage (BECCS). Here the authors explored public perceptions of BECCS by situating the technology in three policy scenarios and found that the policy instrument used to incentivise BECCS significantly affects the degree of public support for the technology.

    Coccolithophores are one of the most abundant phytoplankton and calcifying organisms, well-known to produce intricate calcareous exoskeletons made of coccoliths. Here the authors show, by using X-ray nanotomography, the dependence of the grid size on the calcite nucleation site number and on the mass of coccoliths.

    It is unclear whether CO2-stimulation of photosynthesis can propagate through slower ecosystem processes and lead to long-term increases in terrestrial carbon. Here the authors show that CO2-stimulation of photosynthesis leads to a 30% increase in forest regrowth over a decade of CO2 enrichment.

    Historical and future trends in net primary productivity (NPP) and its sensitivity to global change are largely unknown because of the lack of long-term, high-resolution data. Here the authors show that tree-ring isotopes can be used for inferring interannual variability and long-term changes in NPP.

    Meltwater ponding on top of ice shelves is thought to play a role in ice-shelf flexure and fracture, however in-situ evidence of these mechanisms is lacking. Here, the authors provide field-based evidence showing the impact of the filling and draining of four surface lakes on ice-shelf flexure in Antarctica.

    It is challenging to communicate abstract future climate estimates. Here the authors utilized climate-analog mapping and they identified that North American urban areas’ climate by the 2080’s will become similar to the contemporary climate of locations hundreds of kilometers away and mainly to the south, while many urban areas will have no modern equivalent analogs under the RCP8.5 scenario.

    Abandoned and degraded agricultural lands undergo ecological succession that sequesters atmospheric CO2 as soil carbon, but at low rates. Here the authors show that restoration of high plant diversity provides a greenhouse gas benefit by greatly increasing the rate of soil carbon sequestration on such lands.

Here, the authors show that this pyrogenic OM can retain large quantities of ammonia through covalent bond formation, thereby exerting an important control on nitrogen cycling.

This study shows that the proportion of tropical cyclones that rapidly intensify recently increased in the Atlantic basin, and that this trend is likely due to anthropogenic forcing.

Here the authors find abundant ferromanganese microparticles in oxic pelagic clays, accounting for 14–16% of the new estimate of the global manganese budget (9.2–47.4 Tt).

    The evolution of the Antarctic Ice Sheet is driven by a combination of climate forcing and non-climatic feedbacks. In this review, the authors focus on feedbacks between the Antarctic Ice Sheet and the solid Earth, and the role of these feedbacks in shaping the response of the ice sheet to past and future climate changes.

    It remains unclear when and why the world’s oceans, once largely occupied by bacteria, became dominated by photosynthetic algae. Here, using fossil lipids in million year old rocks, the authors show that predation after the Snowball Earth glaciations created the opportunity for a global shift to algal ecosystems.
