  • Inclusive and equitable geoscience requires identification and removal of structural barriers to participation. Replacing the leaky pipeline metaphor with that of a hostile obstacle course demands that those with power take the lead.

  • The Global Methane Pledge is a good start, but larger cuts in emissions are achievable with current technology. More ambition is needed to help limit warming to 1.5 °C.

  • The Earth’s climate is a complex system and palaeoclimate reconstructions can be used to test and expand on the knowledge gained from physical models during intervals of rapid climate fluctuations.

  • Marine microbes have shaped the climate throughout Earth’s history. Integration of microbial carbon cycling dynamics across a range of spatial scales will be critical for understanding the ocean’s impact in light of a changing climate.

  • We chat with Vincent Ialenti, a University of Southern California Berggruen Fellow, about thinking on geological timescales. Ialenti’s recent book, Deep Time Reckoning (MIT Press, 2020), chronicles his anthropological work on the institution responsible for the long-term safety of a Finnish nuclear waste repository.

  • A more comprehensive understanding of the role of irrigation in coupled natural–human systems is needed to minimize the negative consequences for climate, ecosystems and public health.

  • Cover letters are a ubiquitous but hidden part of the publication process. We share our thoughts on the effective and efficient crafting of these letters and their role in our editorial decision-making.

  • Social scientists and geoscientists must work together to critically evaluate and develop feasible visions for a sustainable future. Is a clean-energy economy more viable than a degrowth future?

  • An update to our policy on reporting requirements for geological and palaeontological materials aims to tackle ethical issues surrounding the collection, traceability and archiving of field samples.

  • Enabling public sharing of scientific data in China not only needs top-down mandates but also incentive mechanisms that boost confidence and willingness to engage in data-sharing practices among Chinese researchers.

  • Land-use-induced ecosystem reduction and degradation has profound impacts on the Earth system. Proceeding with currently unsustainable land use may jeopardize climate and ecosystem restoration targets.

  • Globally, land- and fire-management policies have counterproductively caused cascading ecosystem changes that exacerbate, rather than mitigate, wildfires. Given rapidly changing climate and land-use conditions that amplify wildfire risk, a policy shift to adaptive management of fire regimes is urgently needed.

  • Working spaces and cultures in the geosciences need to change in order to attract, safeguard and retain people with disabilities.

  • Warm intervals in the geological record potentially hold the key to understanding ongoing changes in Earth’s climate. Our ability to unlock this information depends on continued technical and conceptual progress.
