  • In 2021, one in five people in Africa was affected by hunger, and the continent had the highest prevalence of undernourished people globally. We argue that food systems in Africa can be more resilient if their development includes climate adaptation.

  • Large language models can summarize, aggregate, and convey localized climate-related data to people in a cost-effective and expeditious manner. This Comment introduces a simple, proof-of-concept prototype and argues that the approach holds the potential to truly democratize climate information.

  • Blue carbon will not solve climate change. The effect is too small; existing sediment carbon stock is a liability; and there is a timescale mismatch between ancient fossil fuel emissions and uptake by vegetation. Clearer communication would support informed decision-making.

  • The role of law and policy in encouraging a sustainable global diet is often underestimated. I argue that targeted laws and environmental policy are key to bring the agricultural sector on the path towards sustainability.

  • Carbon Dioxide Removal (CDR) is a key element of any mitigation strategy aiming to achieve the long-term temperature goal of the Paris Agreement, as well as national net-zero and net-negative greenhouse gas emissions targets. For robust CDR policy, the credibility of certification schemes is essential.

  • Unmanaged land areas are not included in current national reports on greenhouse gas emissions for the Paris Agreement. Here, we argue that carbon dioxide fluxes from all forest land need to be recorded in order to help tracking progress towards global climate targets.

  • The drivers of trends in methane concentrations in the atmosphere over past decades are still poorly understood. Simulations from a chemistry transport model and box model show that human activity is the main driver of a complex system.

  • India’s green revolution has made the country a world leader in rice and wheat production, but at the expense of people and the environment. Here, we call for transformative changes in its agriculture to reduce greenhouse gas emissions while maintaining production levels.

  • Exposure to poor air quality can damage human health and incur associated costs. The severity of these impacts is not uniform around the globe, but depends on the health and density of the populations.

  • During the February 2023 Turkey-Syria earthquakes, people looked for explanations. As scientists, we did our best to share our knowledge in a way that reached and connected with people beyond the scientific community.

  • A comprehensive aircraft survey of onshore oil and gas infrastructure in British Columbia finds that methane emissions may be 1.7 times higher than the official inventory and introduces a framework for compiling measurement-led regional greenhouse gas emissions data.

  • The human tragedy caused by the earthquake doublet on 6 February 2023 in Turkey and Syria is difficult to comprehend. While earthquake scientists are trying to understand this seismic event, its catastrophic impact highlights heightened risk in the entire region.

  • Careful management of deforested Amazonian land cannot replace, but must complement, efforts to preserve the rainforest. Sustainable agricultural practices that promote diverse uses can help minimise impacts on climate and environment.

  • A mechanistic and predictive hierarchical model explains observed organic carbon burial efficiencies and degradation kinetics, and reveals that upper and lower limits of organic matter activation energies are key to predicting organic matter preservation and degradation rates.

  • The South Atlantic Meridional Overturning Circulation initiative began as a grassroots effort to study the South Atlantic Ocean and its impact on climate. This Comment discusses how, in striving towards this goal, it has also become a platform for the empowerment of women and international scientists.

  • To prevent floods from becoming disasters, social vulnerability must be integrated into flood risk management. This Comment advocates that the welfare of different societal groups should be included by adding recovery capacity, impacts of beyond-design events, and distributional impacts.
