Compound climatic extreme events amplify food insecurity
The increasing co-occurrence of climatic hazards poses growing risks to crop production, yet their implications for rice supply and self-sufficiency remain insufficiently quantified. Here, we combine a vine-copula framework with calibrated ORYZA (v3) model to characterize nonlinear dependencies among climate indicators, estimate the probability of compound climatic events, and assess their impacts on rice yield potential, yield gaps, and national…
Adaptive management for improving livestock production and grassland conservation in pastoral Qinghai, China
Balancing grassland conservation with livestock production often involves trade-offs, yet synergy can be achieved through strategic adjustments in herder behaviors for livestock husbandry, particularly in regions dominated by traditional extensive grazing practices where investigations into optimal solutions that reconcile ecological and economic benefits remain limited. In this study, the grassland‒livestock balance at the county level in Qingha…
Ambitious food system interventions required to mitigate the risk of exceeding Earth’s environmental limits
Warming of northern peatlands increases the global temperature overshoot challenge
Isotopic partitioning of gaseous nitrogen emissions of natural terrestrial ecosystems
We estimated the emissions of different forms of gaseous nitrogen (N) from natural terrestrial ecosystems using newly upscaled soil δ 15 N maps, data-constrained gas partitioning models, and incorporating the previously missing N input flux from rock weathering. The emissions for nitrous oxide (N 2 O), nitric oxide (NO) and dinitrogen (N 2 ) are estimated at 12 ± 3, 19 ± 4, and 12 ± 3 Tg N yr −1 , respectively. The Sixth Phase of Coupled Intercom…
Forest aging limits future carbon sink in China
Global hydrological models continue to overestimate river discharge
Global hydrological models (GHMs) are widely used to assess the impact of climate change on streamflow, floods, and hydrological droughts. For the ‘model evaluation and impact attribution’ part of the current round of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP3a), modelling teams generated historical simulations based on observed climate and direct human forcings with updated model versions. Here we provide a comprehensive ev…
Ambitious food system interventions required to mitigate the risk of exceeding Earth’s environmental limits
Transforming the global food system is essential to avoid exceeding Earth’s environmental limits. A robust evidence base is crucial to assess the scale and combination of interventions required for a sustainable transformation. We developed a risk assessment framework, underpinned by an evidence synthesis of global food system modeling studies, to quantify the potential of individual and combined interventions to mitigate the risk of exceeding gl…
Navigating sustainability trade-offs in global beef production
A strong mitigation scenario maintains climate neutrality of northern peatlands
Vegetation disturbances characterization in the Tibetan Plateau from 1986 to 2018 using Landsat time series and field observations
Disturbances in vegetated land could dramatically affect the process of vegetation growth and reshape the land cover state. The overall greenup of vegetation on the Tibetan Plateau (TP) has almost served as a consensus to date. However, we still lack consistent acquisitions on the timing, the spatial patterns, and the temporal frequency of vegetation disturbance over the TP, limiting the capacity for planning land management strategies. Therefore…
Intergenerational inequities in exposure to climate extremes
Young generations are severely threatened by climate change
Climate change reduces winter overland travel across the Pan-Arctic even under low-end global warming scenarios
Amplified climate warming has led to permafrost degradation and a shortening of the winter season, both impacting cost-effective overland travel across the Arctic. Here we use, for the first time, four state-of-the-art Land Surface Models that explicitly consider ground freezing states, forced by a subset of bias-adjusted CMIP5 General Circulation Models to estimate the impact of different global warming scenarios (RCP2.6, 6.0, 8.5) on two modes …
Climate change-induced greening on the Tibetan Plateau modulated by mountainous characteristics
Global terrestrial vegetation is greening, particularly in mountain areas, providing strong feedbacks to a series of ecosystem processes. This greening has been primarily attributed to climate change. However, the spatial variability and magnitude of such greening do not synchronize with those of climate change in mountain areas. By integrating two data sets of satellite-derived normalized difference vegetation index (NDVI) values, which are indi…
Risk and vulnerability of Mongolian grasslands under climate change
Climate change is projected to increase the aridity of semi-arid ecosystems, including Mongolian grasslands (MG), which provide ecosystem services that support food supply and pastoralist lifestyle. Here, we conducted a grid-scale (0.5° × 0.5°) probabilistic risk assessment of MG under climate change for 40 years (1976–2015) based on probability theory. We evaluated changes of risk (impacts) and vulnerability of MG to drought between the recent t…

A comprehensive quantification of global nitrous oxide sources and sinks
Pronounced and unavoidable impacts of low-end global warming on northern high-latitude land ecosystems
Arctic ecosystems are particularly vulnerable to climate change because of Arctic amplification. Here, we assessed the climatic impacts of low-end, 1.5 °C, and 2.0 °C global temperature increases above pre-industrial levels, on the warming of terrestrial ecosystems in northern high latitudes (NHL, above 60 °N including pan-Arctic tundra and boreal forests) under the framework of the Inter-Sectoral Impact Model Intercomparison Project phase 2b pro…
Evapotranspiration simulations in Isimip2a—Evaluation of spatio-temporal characteristics with a comprehensive ensemble of independent datasets
Actual land evapotranspiration (ET) is a key component of the global hydrological cycle and an essential variable determining the evolution of hydrological extreme events under different climate change scenarios. However, recently available ET products show persistent uncertainties that are impeding a precise attribution of human-induced climate change. Here, we aim at comparing a range of independent global monthly land ET estimates with histori…
Changing the retention properties of catchments and their influence on runoff under climate change
Many studies on drought consider precipitation and potential evapotranspiration (PET) impacts. However, catchment water retention is a factor affecting the interception of precipitation and slowing down runoff which also plays a critical role in determining the risks of hydrological drought. The Budyko framework links retention to the partitioning of precipitation into runoff or evapotranspiration. Applied worldwide, we demonstrate that retention…

The critical role of the routing scheme in simulating peak river discharge in global hydrological models
Global hydrological models (GHMs) have been applied to assess global flood hazards, but their capacity to capture the timing and amplitude of peak river discharge—which is crucial in flood simulations—has traditionally not been the focus of examination. Here we evaluate to what degree the choice of river routing scheme affects simulations of peak discharge and may help to provide better agreement with observations. To this end we use runoff and d…
