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: 08 September 2026; doi:10.1038/s41561-026-02088-w 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: 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 feedback…

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/s41561-026-02087-x Nature Geoscience spoke with Ana Bastos (Leipzig University, Germany) and Sonia I. Seneviratne (ETH Zürich, Switzerland) about how climate change is reshaping forest ecosystems, how forests and land-use change feedback on the climate system, and what this means for land-based climate mitigation strategies.

Nature Geoscience, Published online: 04 September 2026; doi:10.1038/s41561-026-02105-y Advances in forest monitoring techniques are transforming our understanding of how forests gain and lose carbon, respond to environmental change, and influence climate. These insights highlight the potential and limitations of forest-based climate solutions.

Nature Geoscience, Published online: 04 September 2026; doi:10.1038/s41561-026-02066-2 The build-up of soil organic carbon depends less on the amount of substrate carbon available but more on the energy soil microbes can use to grow and leave behind residues, according to a global analysis of microbial energy demand and the energy contained in substrate carbon.

Nature Geoscience, Published online: 04 September 2026; doi:10.1038/s41561-026-02081-3 Satellites are revolutionizing our ability to observe forest ecosystems from space, especially when integrated with field observations, experiments and models. The greatest challenge is no longer a lack of observations, but rather the integration of information and knowledge across scales to better understand r…
