  • Continental margins record the last stages of rifting before a new ocean basin is formed, with their variety reflecting interactions between tectonic, magmatic, sedimentary and hydrothermal processes. This Review provides a process-based understanding of rifted margin formation, gaining insights into their resource potential for the energy transition.

  • Carbon uptake by the ocean has increased alongside rising atmospheric CO2 concentrations, but with substantial variability. This Review examines trends in ocean CO2 uptake and the internal and external factors driving its variability, finding an ocean uptake of –2.7 ± 0.3 Pg C year–1 for the period 1990 through 2019.

  • Subsurface carbon dioxide and green energy storage are enablers to limiting anthropogenic warming to 1.5 °C. This Review assesses the feasibility of expanding carbon dioxide storage to gigatonne scales and explores how this experience could accelerate the development of underground hydrogen storage.

  • Connections between climate and conflict have been the centre of critical debate and discussion. In this Viewpoint, five researchers provide their thoughts and opinions on the topic, outlining the types of conflict that can be linked to climate variability, and how these relationships might evolve with ongoing climate change.
