Methane dissociated from the base of the hydrate stability zone off Mauritania during warm interglacials travelled up to 40 km landward beyond where methane hydrates are typically found before venting out, according to 3D seismic imagery.

Spatial changes in planktonic foraminifera species assemblages reveal steeper thermal gradients in the North Atlantic Ocean during the Last Glacial Maximum than simulated by climate models, according to a macroecological analysis of marine sediment cores.

Spatially distinct ice-sheet growth on the Antarctic Peninsula through the Pleistocene was the result of dynamic topography and pre-glacial landscape evolution, not climate, according to a palaeotopographic reconstruction and ice-sheet modelling.

High-elevation meteorological observations and reanalysis data indicate local cooling and drying near Himalayan glaciers due to enhanced katabatic winds in response to global warming.

Plant diversity stabilizes grassland soil temperature by boosting soil organic carbon and increasing plant leaf area, according to an 18-year plant diversity experiment.

Weathering of mafic and ultramafic lithologies in ophiolites can enhance the preservation of organic carbon through the formation of smectite clays and modulate Earth’s climate, according to a coupled mineral weathering and carbon box model.

Human exploration of the Solar System began on the Moon during the space race of the mid-twentieth century. To facilitate documentation and study of the human influence on the Moon, we argue it is time to designate a ‘Lunar Anthropocene’.

While it may feel cold to the touch, Sheng Fan and David Prior explain that ice on Earth is relatively hot. Understanding ‘hot’ ice physics during deformation is critical in determining future sea-level rise.

China has made progress in improving air quality, but current levels of air pollution still have great health impacts. Dr Qiang Zhang, an atmospheric chemist at Tsinghua University, speaks to Nature Geoscience about air pollution control in China, and the challenges and opportunities faced under global environmental change.

India is currently one of the most polluted regions in the world. Dr Chandra Venkataraman, an expert in climate change and air pollution at the Indian Institute of Technology Bombay, speaks to Nature Geoscience about challenges and opportunities facing air pollution control in India.

Carbonates are key minerals for understanding fluids and their interactions with near-surface environments. Ashley King explores their significance on Earth, and beyond.
