The minerals needed to transport water into the deepest parts of the Earth’s mantle remain unclear. High-pressure and -temperature experiments conducted at lower-mantle conditions suggest that iron oxyhydroxide phases may be important to such transport.Nature Geoscience, Published online: 08 September 2026; doi:10.1038/s41561-026-02067-1
Dense iron oxyhydroxide phases may form from an early basal magma ocean, trapping water and potentially contributing to the formation of thermochemical anomalies in the deep mantle, according to high-pressure and high-temperature experiments.Nature Geoscience, Published online: 08 September 2026; doi:10.1038/s41561-026-02085-z
The soot fraction of global black carbon emissions increased from 16% in 1750 to 35% in 2019, mainly driven by fossil fuel consumption, suggesting a higher warming potential per unit mass, according to an analysis of atmospheric measurements.Nature Geoscience, Published online: 07 September 2026; doi:10.1038/s41561-026-02086-y
During the last ice age, the Atlantic Meridional Overturning Circulation (AMOC) underwent a series of abrupt reorganizations. The global impact of these events reflects the accumulation of heat in the ocean interior during the weak AMOC mode and its loss during the strong mode, facilitated by radiative feedbacks that altered the planetary energy balance.Nature Geoscience, Published online: 04 September 2026; doi:10.1038/s41561-026-02079-x
Nature-based solutions in savannas and grasslands that seek to maximize tree cover and carbon uptake can erode biodiversity, create fragile carbon stocks and disrupt the livelihoods of people who depend on these landscapes, all for uncertain climate benefits.Nature Geoscience, Published online: 04 September 2026; doi:10.1038/s41561-026-02065-3

Opinions grounded in evidence and expertise play an important role in scientific discourse. The most effective opinion pieces do not simply express a viewpoint — they acknowledge limitations, nuance, and diversity of perspectives, and help move the conversations forwards.Nature Geoscience, Published online: 05 August 2026; doi:10.1038/s41561-026-02037-7
The European Union’s climate goals rely on forests as carbon sinks.

Author Correction: Recent active rifting on Venus revealed by wide rift flank upliftsNature 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.
