Climate-change mitigation articles from across Nature Portfolio

Oceans are on the frontline of an array of new marine–climate actions that are both poorly understood and under-regulated. Development and deployment of these interventions is outpacing governance readiness to address risks and ensure responsible transformation and effective action.

Mitigating climate change and ensuring food security require a reconfiguration of the ammonia supply chain through a holistic and region-specific mitigation strategy.

Limiting global warming to 1.5 °C requires aggressive climate pledges, but their impact on land-use strategies remains underexplored. Now, a study reveals that these commitments may drive large-scale cropland loss, intensifying food security risks, especially in the global south.

About 45 percent of Africans believe their government is responsible for climate change action, and the least responsibility is attributed to countries and businesses with high greenhouse gas emissions, according to public survey data and statistical analysis.

Oceans are on the front line of new planned climate actions, but understanding of novel marine-climate intervention development and deployment remains low. Here a survey among intervention practitioners allows identification of science and governance gaps for marine-climate interventions.

Global assessments of the climate change mitigation potential of biochar diverge, and many rely on a dated analysis, but there is strong evidence for gigaton-scale contribution, concludes a synthesis of 19 studies of biochar mitigation potential.

The terrestrial carbon flux—sources and sinks—under land-use change (LUC) is difficult to quantify. Here, using a LUC dataset drawing on remote sensing and forest inventory data, the authors show that in China the carbon sink from LUC (such as afforestation) may be underestimated.

Oceans are on the frontline of an array of new marine–climate actions that are both poorly understood and under-regulated. Development and deployment of these interventions is outpacing governance readiness to address risks and ensure responsible transformation and effective action.

Mitigating climate change and ensuring food security require a reconfiguration of the ammonia supply chain through a holistic and region-specific mitigation strategy.

As demand for flights increases, the global aviation industry must transform to become more sustainable. Here we propose six pathways to set aviation on a path to a greener future that include innovations in aviation fuel, management, and regulations.

Limiting global warming to 1.5 °C requires aggressive climate pledges, but their impact on land-use strategies remains underexplored. Now, a study reveals that these commitments may drive large-scale cropland loss, intensifying food security risks, especially in the global south.

As global food loss and waste continue to rise, innovative recycling strategies are urgently needed. A new study highlights that the transition from landfill disposal to a circular bioeconomy can substantially reduce greenhouse gas emissions and improve sustainability in food systems.
