Nature Climate Change, Published online: 29 July 2024; doi:10.1038/s41558-024-02063-6 Climate impacts are triggering a host of novel bio- and geoengineering interventions to save coral reefs. This Comment challenges heroic scientific assumptions and advocates for a more systemic, evidence-based approach to caring for coral reefs.   

Nature Climate Change, Published online: 29 July 2024; doi:10.1038/s41558-024-02064-5 Reef-building corals are declining globally, putting important ecosystem services at risk. Here we discuss the potential risks and benefits of coral ecological replacement, in which new species are introduced to replace the functional roles of species that have declined or disappeared.   

Nature Climate Change, Published online: 29 July 2024; doi:10.1038/s41558-024-02079-y Coral reefs are at risk from ongoing climate change. We can best serve the reefs by invoking realistic scenarios, empiricism, artificial intelligence and falsification to self-correct the current scientific limits that hinder climate science predictions, communication and policies.   

Nature Climate Change, Published online: 26 July 2024; doi:10.1038/s41558-024-02076-1 Analysis of high-resolution climate models reveals a substantial reduction in global oceanic kinetic energy under global warming. This reduction of oceanic kinetic energy is mainly due to weakened mesoscale eddies in the deep ocean.   

Nature Climate Change, Published online: 26 July 2024; doi:10.1038/s41558-024-02075-2 Studies show climate change will alter the ocean, with increased surface layer kinetic energy. This work, using full ocean depth and high-resolution projections with a high-emission scenario, shows an overall ocean kinetic energy decrease due to a calmer deep ocean with weaker mesoscale eddies.   

Nature Climate Change, Published online: 26 July 2024; doi:10.1038/s41558-024-02057-4 The future of carbon dynamics in the northern high latitudes is uncertain yet represents an important potential feedback under climate change. This study uses a comprehensive observational dataset to show an increasing carbon sink in non-permafrost systems; in permafrost systems uptake was offset by loss.   

Nature Climate Change, Published online: 25 July 2024; doi:10.1038/s41558-024-02059-2 Climate change threatens the role of forests as long-term carbon sinks. Tree planting programmes that incorporate assisted migration of tree species and seed sources can help to mitigate this impact.   

Nature Climate Change, Published online: 25 July 2024; doi:10.1038/s41558-024-02080-5 Assisted migration is the artificial movement of species and populations to increase forest resilience. Here the authors model how targeted assisted migration can preserve or enhance the European forest carbon sink under future climate scenarios.   

Nature Climate Change, Published online: 24 July 2024; doi:10.1038/s41558-024-02081-4 The greenhouse gas abatement costs for two forest restoration methods — natural regeneration and plantations — are estimated by integrating observations on the costs of reforestation projects with other biophysical and economic data. This analysis reveals that a mix of reforestation methods offers greater potential to…

Nature Climate Change, Published online: 24 July 2024; doi:10.1038/s41558-024-02068-1 It is important to understand the cost-effectiveness of natural regeneration and plantations, which are common reforestation methods for mitigation. The authors estimate and map abatement costs for the two approaches across low- and mid-income countries, helping to guide reforestation initiatives.   

Nature Climate Change, Published online: 24 July 2024; doi:10.1038/s41558-024-02066-3 The Southern Ocean takes up substantial amounts of heat and carbon. Here the authors show that it has historically accounted for a much greater proportion of global ocean heat uptake—and link this to aerosols depressing uptake in northern oceans—but that future heat and carbon uptake will…

Nature Climate Change, Published online: 23 July 2024; doi:10.1038/s41558-024-02088-x Climate change is increasing ocean temperature, particularly in the surface waters. Here the authors show that accelerated surface warming in the North Pacific in the past decade is driven by shoaling of the ocean mixed layer with some dampening by increased latent heat loss from the…

Nature Climate Change, Published online: 19 July 2024; doi:10.1038/s41558-024-02055-6 Inadequate information in national adaptation policies limits the ability to track national adaptation progress in Africa. Enhancing coverage, consistency and robustness of these policies offers a clear path to establish effective, nationally led adaptation-tracking infrastructure.   

Nature Climate Change, Published online: 19 July 2024; doi:10.1038/s41558-024-02054-7 Tracking adaptation requires countries’ commitments as the baseline for measuring future progress. By analysing 65 African national adaptation documents, this research finds that most countries fail to provide internally consistent and operational plans, while efforts towards adequacy exist.   

Nature Climate Change, Published online: 18 July 2024; doi:10.1038/s41558-024-02067-2 Currently, no comprehensive scientific methodology of corporate risk quantification, in response to new disclosure regulations, has been proposed in the literature. Here we develop fundamental principles that are important for the appropriate use of climate scenario science in transition risk assessments.   

Nature Climate Change, Published online: 16 July 2024; doi:10.1038/s41558-024-02070-7 The growth and yield of 3,652 wheat genotypes under past and simulated future climates indicate that adaptation to a wide range of environments will decrease by 8.7% for each 1°C of warming. Thus, future breeding strategies must deliver genetically diverse elite lines that can adapt to…

Nature Climate Change, Published online: 16 July 2024; doi:10.1038/s41558-024-02069-0 Given the importance of crop breeding and adaptation for future food security, the authors investigate yield response of wheat cultivars under warming. They find low adaptation to recent warming and low phenotype stability across environments, with further reductions expected under future climates.   

Nature Climate Change, Published online: 12 July 2024; doi:10.1038/s41558-024-02072-5 Governments are increasingly using industrial policy to develop low-carbon economic sectors and catalyse the energy transition. A recent study provides a framework to explain why governments adopt different types of green industrial policy, depending on industry position in the global supply chain and types of uncertainty.   

Nature Climate Change, Published online: 10 July 2024; doi:10.1038/s41558-024-02028-9 Projections of the future climate of small island states and territories are currently limited by the coarse resolution of models. We call for rapid global and regional cooperation to develop projections compatible with small island scales, providing relevant local information and decision-making tools.
