Coastal wetlands restored by Nature-based Solutions can trap more sediments than natural ones, and their efficiency is mainly determined by sediment supply, according to a meta-analysis of studies globally.
Dehydration of serpentinised mantle during subduction of the hyper-extended margin of an approaching continent drove a magmatic flare-up which caused crustal thickening recorded in the Kabyé Massif, Togo, according to petrological and geochronological analyses.
Tropical rainfall variability associated with El Nino-Southern Oscillation increases nonlinearly with rising sea-surface temperatures in a warming climate, through increased moisture sensitivity as well as dynamic contributions, suggest analyses of the CMIP6 climate model simulations.
Transient states influence the sustainable or unsustainable trajectories of social-ecological systems and lead to time lags between rapid regime shifts and the change or intervention which caused them, according to theoretical models of island states.
Summertime low clouds in the Arctic play an important role in inducing sea ice melt as they amplify warming from high pressure systems aloft through radiative effects and feedbacks, according to analyses of observations and model simulations.
Terrestrial chemolithotrophic microbes living on Martian crustal material produce distinct biosignatures which could be detected by future missions searching for evidence of past life, according to experiments on a Noachian Martian meteorite.
Shifts in the mixing regimes of lakes in a changing climate are projected to vary with altitude, with mid-altitude lakes particularly affected, according to simulations of 29 Swiss lakes with a physical lake model and downscaled climate projections.
Removal of the greenhouse gas nitrous oxide from the water column is significant under fully oxygenated conditions, show high latitude Atlantic Ocean bacterial N2O consumption data.
Fossilized anaerobic fungi are identified in the largest impact structure in Europe and may have fuelled methane production in energy-poor anoxic environments, according to microscale observations and isotopic analyses
COVID-19 lockdown-induced low aerosol levels in Western Europe in spring 2020 exerted a far smaller influence on surface irradiation than the dry and cloud-free weather, according to analyses of ground-based and satellite observations and experiments with a radiative transfer model.
Most regions are experiencing mean temperatures which would have been considered extreme in 1880, while what is currently considered extreme may become normal within 10–20 years, according to statistical analyses of regional observational datasets.
The probability of not exceeding the 2 °C climate warming target if all countries meet their nationally determined contributions and continue to reduce emissions lies at around 26%, according to an analysis with a statistically-based probabilistic framework.
Climate actors such as cities, regions, countries and companies show diversity in climate actions with gaps in adaptation and consumption-supply chain emissions reductions, suggests a machine-learning based natural language processing and social network analysis.
Magnesium hydroxide is a sustainable material for CO2 sequestration, according to an acid digestion and electrolysis method using olivine-rich silicate rocks in a fully recoverable system.
Present-day variability of daily maximum temperature at the surface can serve as an emergent constraint on the frequency of heat extremes in a warmer climate, according to tests with a large multi-model ensemble of climate models.
Changes in ice dynamics in the Greenland Ice Sheet are projected to contribute to significantly more mass loss than previously thought, suggesting that proper calibration and accurate representation of ice-ocean interactions are critical.
Regulation improves resilience in resource-based communities but resilience does not guarantee community wellbeing, according to mathematical modeling of resource exploiting industries-community interactions.
The distribution of microplastics in the Eurasian Arctic is controlled by contributions from the Siberian rivers as well as the Atlantic, according to analyses of surface and subsurface water samples.
Hadal trenches—the deepest part of the oceans—are biogeochemically more dynamic and diverse environments than previously suggested, according to in-situ measurements of benthic oxygen uptake rate.
An unsolved fatal accident of 9 Russian mountaineers in the northern Urals in 1959 can be explained by a slab avalanche released due to a slope cut to install the tent and wind-blown snow accumulation affected by an irregular topography, according to analytical and numerical models.
