Protect young secondary forests for optimum carbon removal
Nature Climate Change, Published online: 24 June 2025; doi:10.1038/s41558-025-02355-5
The authors generate ~1-km2 growth curves for aboveground live carbon in regrowing forests, globally. They show that maximum carbon removal rates can vary by 200-fold spatially and with age, with the greatest rates estimated at about 30 ± 12 years, highlighting the role of secondary forests in carbon cycling.Author Correction: Recommendations for producing knowledge syntheses to inform climate change assessments

Author Correction: Recommendations for producing knowledge syntheses to inform climate change assessmentsSocial strategies to engage video gamers in climate action
Nature Climate Change, Published online: 20 June 2025; doi:10.1038/s41558-025-02369-z
Video games are a popular method for climate change communication, but current efforts undervalue the potential role of gaming communities. To empower gaming communities to take climate action, we suggest social strategies including fostering climate change conversations through games and in gaming social spaces, and organizing real-world gaming community events.Navigating the black box of fair national emissions targets
Nature Climate Change, Published online: 16 June 2025; doi:10.1038/s41558-025-02361-7
Fair climate targets aligned with the Paris Agreement can be calculated in multiple ways, yielding diverse outcomes. Researchers unpack how equity, global strategies and political and social uncertainties shape fair share allocations, using them to assess nationally determined contributions and guide global climate finance.Exploring climate futures with deep learning
Nature Climate Change, Published online: 13 June 2025; doi:10.1038/s41558-025-02350-w
Glancing forward to view alternative futures for limiting global warming requires understanding complex societal–environmental systems that drive future emissions. Now a study explores the potential, and limits, of deep learning to generate core characteristics of these futures.Future climate-driven fires may boost ocean productivity in the iron-limited North Atlantic
Nature Climate Change, Published online: 13 June 2025; doi:10.1038/s41558-025-02356-4
Fire emissions can be an important source of nutrients such as iron, particularly for the oceans. Here the authors estimate that climate-change-driven changes in fire emissions could increase iron deposition in ocean ecosystems, enhancing productivity particularly in the North Atlantic.Facebook algorithm’s active role in climate advertisement delivery
Nature Climate Change, Published online: 13 June 2025; doi:10.1038/s41558-025-02326-w
Content delivery algorithms on social media exhibit biases in audience selection, which are understudied in the climate context. This study combines observational analysis and a field experiment to reveal algorithmic bias in Facebook’s climate ad data across location, gender and age groups.Using deep learning to generate key variables in global mitigation scenarios
Nature Climate Change, Published online: 13 June 2025; doi:10.1038/s41558-025-02352-8
Integrated assessment model-based scenarios are commonly used to project future emission pathways but suffer from submission biases and high computational cost. Here researchers develop a deep learning framework to generate synthetic scenarios and replicate key variables across a wide range of mitigation ambitions.Recommendations for producing knowledge syntheses to inform climate change assessments
Nature Climate Change, Published online: 10 June 2025; doi:10.1038/s41558-025-02354-6
Climate change assessment reports are increasing in complexity as the knowledge base grows exponentially. In this Perspective, the authors advocate, and provide recommendations, for knowledge synthesis to become more common as a way to better inform such assessments.Conflicting selection on flowering time

There can be a disconnect between everyday life and the natural world, but a healthy diverse environment, where humanity can thrive, requires collective action to address the threats from climate change and development.European Union needs large heat pump and targeted renovation subsidies to meet heating targets
Nature Climate Change, Published online: 05 June 2025; doi:10.1038/s41558-025-02342-w
Current European Union policies are insufficient to achieve residential heating decarbonization targets. Substantial subsidies for heat pumps and carefully targeted incentives for home renovation are critical to efficiently and affordably meet climate goals. We emphasize the importance of adapting strategies to national contexts.Improving cost–benefit analyses for health-considered climate mitigation policymaking
Nature Climate Change, Published online: 05 June 2025; doi:10.1038/s41558-025-02351-9
Mitigation actions can have large-scale health co-benefits, which, however, are not effectively incorporated into policy design and implementation. This Perspective overviews the health co-benefits and cost-effectiveness of climate policies and discusses ways to improve their policy relevance.Meeting climate target with realistic demand-side policies in the residential sector
Nature Climate Change, Published online: 05 June 2025; doi:10.1038/s41558-025-02348-4
Decarbonizing the residential sector is essential for net-zero targets, and the EU has established ambitious policy packages with various instruments. This research shows that beyond carbon trading programmes, massive heat-pump subsidies and targeted energy renovation incentives are needed.Author Correction: Explaining the adaptation gap through consistency in adaptation planning

Nature Climate Change, Published online: 03 June 2025; doi:10.1038/s41558-025-02346-6
Selective migration patterns emerge in flood-prone regions in the USA. The sociodemographic profiles of individuals who were more inclined to move in or out of flood-prone areas were strikingly different. Media sentiment aggravates population replacement in these regions, leading to short-term structure changes in the housing market and long-term socioeconomic decline.Assessing risk of ecosystem collapse in a changing climate
Nature Climate Change, Published online: 02 June 2025; doi:10.1038/s41558-025-02324-y
In this Perspective, the authors discuss how to robustly consider climate change impacts in ecosystem risk assessments. They highlight challenges in defining impacts, indicators and thresholds, in collating data, and in estimating and reporting risk, and propose solutions to inform conservation.
