  • Earth sciences are fundamental to tackling climate change, natural hazards and the energy transition, yet universities worldwide are putting geoscience departments on the chopping block — right when they are needed most.

    Editorial
  • Grasslands provide key ecosystem services, but their protection is often ignored in sustainable policy. This Perspective describes grassland degradation and sets out the steps needed to protect these systems and promote their restoration.

  • The El Niño–Southern Oscillation (ENSO) has global climatic implications, necessitating understanding of its observed and projected changes. This Review brings together knowledge of ENSO in a warming climate, revealing projected increases in ENSO magnitude, as well as ENSO-related rainfall and sea surface temperature variability.

  • Supereruptions are the endmember of explosive volcanic activity, yet, their magmatic processes and eruption dynamics are debated. This Review synthesizes data from 13 Quaternary supereruptive events with geophysical monitoring of active caldera volcanoes to highlight the diversity in large, modern, silicic magmatic systems.

  • The Indian Ocean has undergone substantial heat and freshwater changes. This Review uses various data sources to examine the causes of contemporary and longer-term hydrological changes, revealing that trends over the twentieth century are linked to anthropogenic forcing, but that those since 1980 are related to the Interdecadal Pacific oscillation.
