Research on the energy transition needs to involve all communities and requires breaking the paradigm of traditional industry-funded research, argues Jef Caers from his personal story.

Temporarily overshooting climate targets is a distinct possibility given our current emissions trajectory. It is crucial that we understand which of the associated impacts are reversible, and to what extent.

Inspired by the mineralogist Shulamit Gross’s studies of one of the world’s unique mineral factories, Michael Anenburg discusses the pyrometamorphic minerals formed by fire in the Dead Sea desert.

Rock organic carbon from glacial runoff, once assumed to be non-bioavailable, is identified as a substrate used by marine sedimentary microbes. This challenges the traditional view that rock organic carbon bypasses the active carbon cycle and indicates an additional source of fossil greenhouse-gas emissions on geological, or possibly even shorter, timescales.

Sediment lenses trailing subducting seamounts could maintain long-lasting fluid pressures and support slow-slip behaviour at sediment-rich subduction zones, according to three-dimensional seismic surveys of the Hikurangi margin.

Deciphering the contribution of mantle convection to Earth’s surface elevation remains challenging, but it may have a dominant influence on mountain-building at subduction zones, according to a new study reconstructing the topographic evolution of Calabria.

High-resolution satellite observations reveal that large lakes on the Tibetan Plateau have total nitric oxide emissions comparable to anthropogenic emissions from individual megacities worldwide.

Ancient, rock-derived organic matter is consumed by micro-organisms in Arctic fjord sediments despite its presumed limited bioavailability, representing a potential source of greenhouse gas emissions, according to compound-specific radiocarbon analyses of lipids from living bacteria.

The formation of continental crust may have trapped —and thus not degassed—substantial amounts of magmatic nitrogen over Earth’s history, according to geochemical analyses of igneous rocks from the Hekla volcanic system in Iceland.

Interactions between subducting slabs and the 660-km mantle transition zone can influence mantle convection and forearc uplift, according to rock uplift histories of the Calabrian forearc spanning the past 30 million years.

The hyper-arid climate of modern East Antarctica only arose in the late Miocene, millions of years after the interval of rapid ice-sheet expansion, according to meteoric beryllium-10 concentrations within the permafrost.

Correlation between large igneous province activity and iron formation ages suggests that subducted iron formations may have facilitated mantle plume upwelling in the Archaean and Proterozoic Earth.

Lightning can produce bioavailable nitrogen oxides, but it is unknown whether this was a substantial nutrient source for Earth’s earliest biosphere. Comparison of nitrogen isotope measurements from spark discharge experiments to those from the rock record suggests that lightning was likely not the main source of bioavailable nitrogen for the biosphere throughout most of Earth’s history.

Fine-grained pyroclastic deposits can be fluidized by decompression following the passage of dilute pyroclastic density currents, generating hazardous, highly mobile flows, according to analogue experiments and numerical simulations.

Spark discharge experiments suggest lightning was not the main source of bioavailable nitrogen for the established Archaean biosphere, but could have been significant for Earth’s earliest ecosystems.

Nature Geoscience spoke with Dr Shlomit Sharoni, an ocean biogeochemist at Massachusetts Institute of Technology, and Dr Kelly Andersen, a tropical ecologist at Nanyang Technological University about the interplay between phosphorous cycling and the ecosystems they study.

From Dutch painters to ocean sediments, Caroline Slomp discusses the role vivianite plays in the distribution of phosphorus, an essential nutrient for life.
