Wide flanks of rift uplifts on Venus indicate recent rifting activity

31 July 2026 at 01:00

Nature Geoscience, Published online: 31 July 2026; doi:10.1038/s41561-026-02049-3

Comparing numerical models of active and inactive rifts on Venus with observations reveals that rift valleys on Venus with wide rift flank uplifts are active (or were recently). These rifts also might experience faster tectonic extension rates than previously assumed, which might be associated with rising mantle plumes from greater depths.

The dominant role of temperature in seasonal ozone sensitivity changes in China

Nature Geoscience, Published online: 31 July 2026; doi:10.1038/s41561-026-02036-8

Ozone regime analyses suggest that temperature outweighs anthropogenic emissions and actinic flux in controlling seasonal variations in ozone sensitivity over China.

Limited remineralization of Arctic permafrost-derived organic carbon in nearshore marine sediments

Nature Geoscience, Published online: 31 July 2026; doi:10.1038/s41561-026-02060-8

Only 10% of organic carbon from thawing Pleistocene permafrost in the Arctic that is buried in marine sediments ends up re-entering the active carbon cycle, according to a carbon isotope analysis of sediments from off Qikiqtaruk (Herschel Island) in Canada.

Threefold increase in atmospheric–riverine compound heatwaves under climate change

Nature Geoscience, Published online: 30 July 2026; doi:10.1038/s41561-026-02040-y

Co-occurring atmospheric and river heatwaves have tripled since the 1980s across the USA and Europe, and are projected to become the norm by 2100, according to model simulations.

Recent active rifting on Venus revealed by wide rift flank uplifts

Nature Geoscience, Published online: 24 July 2026; doi:10.1038/s41561-026-02044-8

Comparisons between thermomechanical models and Venusian rift morphologies indicate that rifts on Venus are still, or were recently, active and may have undergone faster extension than usually assumed, potentially because of mantle plume activity.

Future tropical cyclone rainfall constrained by increased atmospheric dryness

24 July 2026 at 01:00

Nature Geoscience, Published online: 24 July 2026; doi:10.1038/s41561-026-02047-5

Climate model ensembles suggest tropical cyclones will bring more rain as the world warms, but increases may be smaller than expected. Atmospheric dryness reduces how much rain storms produce, offsetting extra moisture and stronger storms.

European summer drying largely driven by atmospheric circulation changes since the 1980s

Nature Geoscience, Published online: 22 July 2026; doi:10.1038/s41561-026-02050-w

Shifting atmospheric circulation patterns over Europe since the 1980s have been the major cause of increasingly severe droughts on the continent, according to nudged circulation climate model simulations.

Extreme warming fans the flames during mass extinctions

21 July 2026 at 01:00

Nature Geoscience, Published online: 21 July 2026; doi:10.1038/s41561-026-02058-2

Most major mass extinctions in Earth history are linked to greenhouse gas emissions causing warmer and drier climates. Research shows these perturbations also led to widespread wildfires and the expansion of fern savannahs during one of the most acute events at the end of the Triassic period, potentially holding lessons for the future.

Continental-scale fern savannah wildfires during end-Triassic greenhouse warming

Nature Geoscience, Published online: 21 July 2026; doi:10.1038/s41561-026-02048-4

Fern savannahs spread rapidly following the collapse of the forest ecosystem during the end-Triassic mass extinction, setting the conditions for widespread wildfires, according to an analysis of the darkening of fossil pollen and spores.

Eastern Himalayan syntaxis formation controlled by slab flattening and crustal shear localization

Nature Geoscience, Published online: 20 July 2026; doi:10.1038/s41561-026-02045-7

The Eastern Himalayan orogenic corner, or syntaxis, is largely formed by flattening of the Indian slab and shear localization in weak crust, which may affect development of the orogenic system, according to thermomechanical models.

Deeper solar wind penetration on the Moon’s farside from noble gas records

Nature Geoscience, Published online: 15 July 2026; doi:10.1038/s41561-026-02042-w

Krypton and xenon in lunar farside soils are derived from solar wind and suggest deeper penetration because the solar wind is not slowed by Earth’s magnetosphere. This contrasts with the nearside, according to noble gas analyses of soil samples collected by the Chang’e-6 mission.

High-resolution imaging of a sediment core reconstructs past monsoon seasonality

14 July 2026 at 01:00

Nature Geoscience, Published online: 14 July 2026; doi:10.1038/s41561-026-02025-x

Assessing the response of the South Asian monsoon to rapid climate change requires understanding its seasonal driving mechanisms under changing climate conditions. Now, advanced geochemical imaging of an Arabian Sea sediment core reveals distinct seasonal responses to global and high-latitude climate forcing in the South Asian monsoon variability during the last deglaciation.

Reduced tropical rain-band asymmetry through the seasonal cycle

Nature Geoscience, Published online: 14 July 2026; doi:10.1038/s41561-026-02046-6

A strong seasonal cycle shifts the tropical rain band towards symmetry by amplifying southern rainfall during austral summer through heating and ocean–atmosphere feedback, helping to explain persistent climate model biases, according to model simulations.

Hydroclimate controls Congo peatland net oxygen release over the past 10,600 years

Nature Geoscience, Published online: 10 July 2026; doi:10.1038/s41561-026-02031-z

The oxygen surplus from carbon burial in Congo peatlands reached 83 petagrams of net atmospheric oxygen equivalents during the Holocene, suggesting global peatlands may have offset 40–95% of continental weathering oxygen sinks, according to a peat core.

West versus Central Tibet exhumation difference influenced by Indian slab underthrusting

Nature Geoscience, Published online: 10 July 2026; doi:10.1038/s41561-026-02043-9

The extent of Indian continental underthrusting beneath Western Tibet influences its moderate-to-rapid exhumation, relative to slow exhumation in Central Tibet, according to thermochronological data and exhumation history modelling.
