Enhance responsible governance to match the scale and pace of marine–climate interventions
Nature Climate Change, Published online: 03 April 2025; doi:10.1038/s41558-025-02292-3 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.
Novel marine-climate interventions hampered by low consensus and governance preparedness
Nature Climate Change, Published online: 03 April 2025; doi:10.1038/s41558-025-02291-4 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.
China’s carbon sinks from land-use change underestimated
Nature Climate Change, Published online: 01 April 2025; doi:10.1038/s41558-025-02296-z 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.
Constrained Earth system models show a stronger reduction in future Northern Hemisphere snowmelt water
Nature Climate Change, Published online: 28 March 2025; doi:10.1038/s41558-025-02308-y Many climate models overestimate the snow amount in the Northern Hemisphere despite strong warming. Here the authors find that light snowfall and snow melting processes drive this mismatch and use these relationships to constrain future projections of snow water resources.
Global distribution, quantification and valuation of the biological carbon pump
Nature Climate Change, Published online: 27 March 2025; doi:10.1038/s41558-025-02295-0 This study quantifies and values the carbon stored in the ocean due to biological processes. With uptake in the order of 2.8 Gt per year, valued at around US$1 trillion annually (at a carbon price of US$90 per ton of CO2), this service should be included in…

Drought hinders the advance of spring phenology through ecosystem memory effects
Nature Climate Change, Published online: 26 March 2025; doi:10.1038/s41558-025-02274-5 Analysis of satellite observations and in situ phenology records revealed a delayed onset of spring after drought in northern ecosystems. These delays are regulated by both endogenous memory within plants and exogenous memory of the environment, with the latter having a dominant role.
Peatland microalgae are unsung heroes of climate change mitigation
Nature Climate Change, Published online: 26 March 2025; doi:10.1038/s41558-025-02272-7 Under climate warming, increased microbial carbon emissions could diminish the vast carbon stores held in northern peatlands. This large-scale experimental study reveals that warming amplifies carbon uptake by peatland microalgae and partially offsets warming-related increases in microbial carbon emissions.
Coastal investment in the age of climate change
Nature Climate Change, Published online: 26 March 2025; doi:10.1038/s41558-025-02299-w Cities have historically benefitted from coastal access, but sea-level rise may turn this advantage into a vulnerability. Government investment should account for future climate risks.
Fossil fuel subsidy reforms have become more fragile
Nature Climate Change, Published online: 26 March 2025; doi:10.1038/s41558-025-02283-4 Governments around the world have pledged to reduce fossil fuel subsidies, yet the actual implementation has not been measured. With a unique dataset and approach, researchers find since 2016 there are more frequent reforms, yet most of them do not survive over 12 months.
Rising temperatures reduce the predictability of agricultural drought
Nature Climate Change, Published online: 25 March 2025; doi:10.1038/s41558-025-02290-5 Drought predictability has a large impact on climate adaptation plans, but its future changes are often unknown. A drought predictability model reveals that increases in global temperatures of 2 °C or 3 °C would cause a significant (p
Food security or climate action
Nature Climate Change, Published online: 24 March 2025; doi:10.1038/s41558-025-02297-y 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.
Heterogeneous pressure on croplands from land-based strategies to meet the 1.5 °C target
Nature Climate Change, Published online: 24 March 2025; doi:10.1038/s41558-025-02294-1 Many countries are relying on land-based strategies to meet the climate targets set out in the Paris Agreement, putting pressure on land resources. Here the authors show a global reduction in cropland area under current climate pledges, with implications for trade and food security.
Local fossil fuel ad ban as a catalyst for global change
Nature Climate Change, Published online: 21 March 2025; doi:10.1038/s41558-025-02267-4 The Hague in the Netherlands was the first city in the world to enact a law prohibiting advertisements for fossil fuel products and services. Although the ban is restricted to The Hague’s jurisdiction, the decision to implement the ban challenges norms and conventions that drive fossil-fuel…

Glaciers give way to new coasts
Nature Climate Change, Published online: 21 March 2025; doi:10.1038/s41558-025-02275-4 Climate change is causing rapid shrinkage of high-latitude glaciers, fundamentally altering the nature of Arctic landscapes. Now, research quantifies the substantial, yet under-reported, development of new coastlines and islands that are revealed as marine-terminating glaciers fall back from the sea.
New coasts emerging from the retreat of Northern Hemisphere marine-terminating glaciers in the twenty-first century
Nature Climate Change, Published online: 21 March 2025; doi:10.1038/s41558-025-02282-5 As marine-terminating glaciers retreat, they reveal new coastlines in many regions. Here the authors use satellite data to quantify these changes for the Northern Hemisphere, finding that between 2000 and 2020, a total of 2,466 km of new coastline has been uncovered.
Colonial legacies in tropical forestry hinder good management

Drought legacies delay spring green-up in northern ecosystems
Nature Climate Change, Published online: 20 March 2025; doi:10.1038/s41558-025-02273-6 The authors investigate the impacts of drought legacy on springtime leaf unfolding and green-up. They show that drought delays springtime phenology, primarily through exogenous environmental memory effects, and suggest that future spring advances may be dampened by increasing drought.
Microbial photosynthesis mitigates carbon loss from northern peatlands under warming
Nature Climate Change, Published online: 20 March 2025; doi:10.1038/s41558-025-02271-8 The authors use experimental and modelling approaches to understand the response of microbial photosynthesis to peatland warming. They show that warming amplifies microbial photosynthesis, which could offset rising CO2 emissions from northern peatlands by 6.0–13.7% in 2100 (SSP 2-4.5–SSP 5-8.5).
