The 2015–2018 summer drought event was unprecedented in Western and Central Europe over the last 400 years, whereas multi-year droughts were more frequent during the Maunder Minimum, according to a hydroclimate reconstruction using tree-ring stable isotopes.

The nanometer silica grains that were detected by Cassini in Saturn’s E-ring can be explained by hydrothermal activity on Enceladus’ seafloor and upward transport through the ocean, according to analytical modeling of convection and particle entrainment in Enceladus’ ocean.

In most developed economies where decarbonisation processes are already in place, economic crises have coincided with a peak and subsequently declining emissions as a result of lower carbon and energy intensities, according to a statistical analysis of 45 countries between 1965 and 2019.

Installing heat pumps instead of traditional gas boilers for heating purposes could lead to a drastic reduction in the consumption of natural gas in Germany, according to numerical simulations that combine gas and electricity markets

Fabric-retentive dolostones preserve the lithium isotope composition of the seawater in which they formed and could provide a high-resolution record to complement or extend foraminiferal proxy records, as indicated by isotopic analyses of Neogene dolostones from the South China Sea.

The tsunami from the Storegga slide 8,150 years ago was caused by a smaller submarine landslide than previously thought, which implies higher hazard in the region, according to analyses of geophysical data and sediment cores that suggest an older origin of part of the scar.

Thick transiting ice blocked newly formed sea ice from exiting the Terra Nova Bay polynya during a shrinking event in 2013 and had a stronger influence on polynya area than katabatic winds or air temperature changes, according to an analysis of sea ice and meteorological data.

Sprouting and early growth of plants in wetlands can be inhibited by freeze-thaw cycles via denitrification and reduction of soil nitrogen, according to a temperature-controlled experiment in the Momoge wetland in China.

Trench-parallel ridges on the Rivera plate subducting beneath W Mexico, control upper-plate tectonics and elastic structure, and act as unstable asperities, enabling shallow megathrust seismogenesis, according to seismic imaging and tomographic modeling.

Whether diets will evolve through social interventions to move closer to sustainable agriculture is being investigated in a growing and promising area of research.

Careful management of deforested Amazonian land cannot replace, but must complement, efforts to preserve the rainforest. Sustainable agricultural practices that promote diverse uses can help minimise impacts on climate and environment.

A mechanistic and predictive hierarchical model explains observed organic carbon burial efficiencies and degradation kinetics, and reveals that upper and lower limits of organic matter activation energies are key to predicting organic matter preservation and degradation rates.

The South Atlantic Meridional Overturning Circulation initiative began as a grassroots effort to study the South Atlantic Ocean and its impact on climate. This Comment discusses how, in striving towards this goal, it has also become a platform for the empowerment of women and international scientists.

For all peer reviewed articles submitted from 23^rd January 2023, we will publish the editor decision letters, reviewer reports and author responses, together with the published paper. Reviewers can choose to remain anonymous or reveal their identity.

To prevent floods from becoming disasters, social vulnerability must be integrated into flood risk management. This Comment advocates that the welfare of different societal groups should be included by adding recovery capacity, impacts of beyond-design events, and distributional impacts.
