Erosion rate is a first-order control of abundance and persistence of soil organic carbon in hilly and mountainous regions, according to analyses of the physiochemical properties of soils from field sites in Oregon, USA.
Proto-monsoon expansion doubled rainfall in Central Asia during an early Eocene hyperthermal, leading to a rapid if transient expansion of forests replacing the steppe-desert.
Ocean sediment records suggest that the modern Antarctic Circumpolar Current did not exist before the late Miocene cooling, indicating its origin is linked to the expansion of the Antarctic Ice Sheet.
Petrological reaction experiments and magnesium isotope data suggest that reactive flow with mantle cumulates can explain the composition of Ti-rich basaltic magmas.
The amount of secondary organic aerosol produced from wildfire emissions is much higher than previously thought, according to model simulations of evolution of individual species of organic aerosol over time.
Wind tunnel experiments and numerical modelling reveal the existence of two distinct ripples on Earth: centimetre-scale impact ripples and decimetre-scale hydrodynamic ripples, akin to those in water and on Mars.
Mobilization of in-use rare-earth element stocks in regions of high consumption can ease dependence on regions of rare-earth extraction, according to dynamic integrated modelling combining material flow and scenario analysis.
Soil moisture is the primary driver of variability in dryland carbon and water cycling, according to a synthesis of eddy covariance, remote sensing and land surface model data from the western United States.
Organic carbon in the top layer of mineral soils in cold regions is dominated by the particulate fraction, according to analyses in Arctic and alpine ecosystems.
Soil carbon substrates affect how methane and CO2 emissions from global wetlands change in response to climate warming, according to global analyses of temperature sensitivity of wetland carbon emissions.
The atmosphere has dried across most regions of Europe in recent decades, a trend that can be attributed primarily to human impacts, according to tree ring records spanning 400 years and Earth system model simulations.
Geological structure and pore fluid pressure in the subduction zone forearc govern the size and recurrence of megathrust earthquakes in Chile, according to quasi-dynamic simulations of the seismic cycle.
Hydrothermal venting makes limited contribution to the inventory of oceanic mercury compared with anthropogenic inputs, according to measurements at mid-ocean ridges.
Methane dissociated from the base of the hydrate stability zone off Mauritania during warm interglacials travelled up to 40 km landward beyond where methane hydrates are typically found before venting out, according to 3D seismic imagery.
Spatial changes in planktonic foraminifera species assemblages reveal steeper thermal gradients in the North Atlantic Ocean during the Last Glacial Maximum than simulated by climate models, according to a macroecological analysis of marine sediment cores.
Spatially distinct ice-sheet growth on the Antarctic Peninsula through the Pleistocene was the result of dynamic topography and pre-glacial landscape evolution, not climate, according to a palaeotopographic reconstruction and ice-sheet modelling.
High-elevation meteorological observations and reanalysis data indicate local cooling and drying near Himalayan glaciers due to enhanced katabatic winds in response to global warming.
Plant diversity stabilizes grassland soil temperature by boosting soil organic carbon and increasing plant leaf area, according to an 18-year plant diversity experiment.
Weathering of mafic and ultramafic lithologies in ophiolites can enhance the preservation of organic carbon through the formation of smectite clays and modulate Earth’s climate, according to a coupled mineral weathering and carbon box model.
While global ocean redox patterns during the end Triassic were similar to today, pulses of localized anoxia were probably linked to mass extinctions on continental shelves, according to analysis of molybdenum records.
