Uptake of 13C-depleted anthropogenic carbon dioxide in the surface ocean may eliminate or reverse the natural vertical gradient in the isotopic composition of dissolved inorganic carbon in the ocean, analogous to events at the Paleocene-Eocene Thermal Maximum, suggest ocean model simulations.
Subaerial volcanism may provide an important source of micronutrients to the surface ocean through the deposition of iron and manganese rich ash, according to Monte Carlo simulations based on ash composition and eruption volume data.
Use of CO2 mineralisation in the cement industry could be profitable and cut CO2-equivalent emissions by up to a third, if the process is eligible for carbon trading and its products are used in construction, suggests integrated techno-economic modelling.
Migration of hydrothermal fluids and microseismicity in the Krýsuvík geothermal area, Iceland, was controlled by the development of fractures and permeability following a moderate sized earthquake, according to data from two passive seismic surveys
New subduction zones can form via a self-replicating process, without the need for external forcing, when buoyant blocks reach pre-existing subduction trenches and cause polarity reversals, according to 3D numerical modelling
The rate of deformation in Antarctic ice shelves is proportional to stress to the power of 4, not 3 as often used in models, according to a calibration of Glen’s Flow Law with satellite remote sensing data from Antarctic ice shelves.
A distinct kink in the slope of the Gutenberg-Richter distribution of deep earthquakes in the northwest Pacific is identified by unsupervised machine learning and could indicate the rim of the metastable olivine wedge.
Optimising the spatial distribution of global croplands could substantially reduce carbon emissions and biodiversity loss associated with rain-fed crop production, according to a mathematical framework applied to environmental impact and crop yield data
Stormwater retention ponds emit the greenhouse gases carbon dioxide and methane but store increasingly large amounts of carbon in their sediments over time, according to an observational study of carbon dynamics in stormwater ponds in southwest Florida.
A cratonic embayment that likely formed during the Neoproterozoic rifting of the supercontinent Rodinia is identified under the East Antarctic ice sheet through analyses of aeromagnetic and other geophysical data
Adapting to climate change through Nature-Based Solutions can reduce the severity of hydrological droughts caused by human influence on the climate, according to a multi-model joint-attribution of climate and landscape-vegetation states developed in South Africa.
Tropical cyclones produce exceptionally negative rainwater isotopic values that can serve as a proxy to reconstruct past large tropical cyclones, suggests high-resolution rainwater sampling during Hurricane Harvey in 2017
The Holocene Humid Period in Northern Arabia may only have lasted for less than 1000 years and was characterised by substantial regional climatic variability, according to a high-resolution multi-proxy varved lake record from Tayma, Saudi Arabia.
Biogeochemical recycling that helps maintain Earth’s habitability is promoted by persistence-based natural selection, even when such recycling depends upon species with relatively low organism-level fitness, according to modeling of life-environment coevolution
Targeted activities to avoid tropical forest loss in data poor areas can be guided by remotely sensed high resolution, near-real-time information on forest disturbance and aboveground carbon stocks, as demonstrated for 23 countries in Africa.
The modern-like solar cycle might have evolved as early as 2.47 billion years ago, according to synchrotron-radiation-based micro-scale analyses of a Precambrian banded iron formation from the Kuruman Formation, South Africa.
Greening in high mountain Asia between 2003 and 2020 was driven by warming at high elevations, increased precipitation in forested regions and enhanced irrigation in croplands, according to a multivariate analysis of remote sensing data.
Arctic warming amplification is intensified in a low-emission scenario after the mid-2040s, compared to a high-emission scenario, because of a continuing ice-albedo feedback, according to 50-member ensemble simulations with a climate model.
