A step up for geoengineering   p855
The clock is ticking for climate change mitigation. Geoengineering is gaining ground as an option, but it needs to be examined at a large scale to determine its effectiveness and associated risks.



Getting to the bottom of the ocean   pp857 - 858
Casimir de Lavergne, Gurvan Madec, Xavier Capet, Guillaume Maze and Fabien Roquet



No fudging on geoengineering   pp859 - 860
Andy Parker and Oliver Geden
The Intergovernmental Panel on Climate Change is preparing a report on keeping global warming below 1.5 °C. How the panel chooses to deal with the option of solar geoengineering will test the integrity of scientific climate policy advice.

Atmospheric science: Energy and precipitation   pp861 - 862
Aaron Donohoe
The latitude of the tropical rainbelt is constrained by the energy balance between hemispheres. An expansion of this theory that includes longitudinal variations of atmospheric heating can predict regional changes in tropical precipitation.

Volcanology: Petit spots go big   pp862 - 863
Jonathan E. Snow
Mantle enrichment processes were thought to be limited to parts of oceanic plates influenced by plumes and to continental interiors. Analyses of mantle fragments of the Pacific Plate suggest that such enrichment processes may operate everywhere.

Carbon cycle: Ocean dissolved organics matter   pp864 - 865
Rainer M. W. Amon
Large quantities of organic carbon are stored in the ocean, but its biogeochemical behaviour is elusive. Size-age-composition relations now quantify the production of tiny organic molecules as a major pathway for carbon sequestration.

Global warming: Clouds cooled the Earth   pp865 - 867
Thorsten Mauritsen
The slow instrumental-record warming is consistent with lower-end climate sensitivity. Simulations and observations now show that changing sea surface temperature patterns could have affected cloudiness and thereby dampened the warming.

Geodynamics: Surface sculpting by hidden agents   pp867 - 869
Nicky White
Tectonic plate interiors are often regarded as relatively inactive. Yet, reconstructions of marine terrace uplift in Angola suggest that underlying mantle flow can rapidly warp Earth's surface far from obviously active plate boundaries.

Impact of decadal cloud variations on the Earth's energy budget   pp871 - 874
Chen Zhou, Mark D. Zelinka and Stephen A. Klein
Cloud feedbacks strongly influence the magnitude of global warming. Climate model simulations show that these feedbacks vary strongly as the spatial patterns of sea surface temperatures change over time.

Tropospheric ozone change from 1980 to 2010 dominated by equatorward redistribution of emissions   pp875 - 879
Yuqiang Zhang, Owen R. Cooper, Audrey Gaudel, Anne M. Thompson, Philippe Nedelec et al.
Ozone is an air pollutant and a greenhouse gas. Simulations with a global chemistry transport model reveal that the spatial distribution of ozone precursor emissions dominates the global ozone burden, and that emissions in the tropics matter most.

Substantial global carbon uptake by cement carbonation   pp880 - 883
Fengming Xi, Steven J. Davis, Philippe Ciais, Douglas Crawford-Brown, Dabo Guan et al.
Cement production is a source of CO2. Analysis of carbonation, a process that sequesters CO2 during the lifetime of cement, suggests that between 1930 and 2013, it has offset 43% of CO2 emissions from cement production globally.

Marine methane paradox explained by bacterial degradation of dissolved organic matter   pp884 - 887
Daniel J. Repeta, Sara Ferron, Oscar A. Sosa, Carl G. Johnson, Lucas D. Repeta et al.
A lot of methane is emitted from oxygenated seawater, where its production should be inhibited. Seawater incubations and organic matter characterizations reveal that bacteria aerobically produce methane from phosphonates in organic matter.

Pacific carbon cycling constrained by organic matter size, age and composition relationships   pp888 - 891
Brett D. Walker, Steven R. Beaupre, Thomas P. Guilderson, Matthew D. McCarthy and Ellen R. M. Druffel
Organic matter represents a large pool of carbon in the ocean. Radiocarbon and chemical analyses suggest that larger particles are preferentially remineralized in the Pacific Ocean, with smaller particles and molecules persisting longer.

Regional energy budget control of the intertropical convergence zone and application to mid-Holocene rainfall   pp892 - 897
William R. Boos and Robert L. Korty
Shifts in the latitude of the tropical rainfall band are constrained by meridional energy fluxes. Calculations show that combining zonal and meridional energy fluxes can explain past regional rainfall variations like the African Humid Period.

Pre-subduction metasomatic enrichment of the oceanic lithosphere induced by plate flexure   pp898 - 903
S. Pilet, N. Abe, L. Rochat, M.-A. Kaczmarek, N. Hirano et al.
Oceanic lithosphere is recycled into the mantle at subduction zones. Analysis of fragments of lower oceanic lithosphere brought to the surface by petit-spot volcanoes suggests this lithosphere may be enriched by melts prior to subduction.

Recycling of subducted crustal components into carbonatite melts revealed by boron isotopes   pp904 - 908
Samuel R. W. Hulett, Antonio Simonetti, E. Troy Rasbury and N. Gary Hemming
The origin of carbon-rich magmas is unclear. Boron isotopic analysis of carbonatite magmas that formed over the past 2.6 billion years reveals a link to carbon recycled during tectonic plate subduction.

Rapid mantle-driven uplift along the Angolan margin in the late Quaternary   pp909 - 914
R. T. Walker, M. Telfer, R. L. Kahle, M. W. Dee, B. Kahle et al.
Mantle flow can warp Earth's surface. Reconstructions of surface deformation in Angola over the past 45,000 years reveal rapid uplift of about 2 mm per year, implying that mantle-induced uplift may occur in quick pulses.
