Land use impacts the environmental benefits of wind energy farms in China Open
Wind energy plays a vital role in meeting rising electricity demand and climate goals, but its land-use footprints from vegetation removal, construction, and road sprawl may overestimate greenhouse gas (GHG) mitigation benefits. Here we us…

Spatiotemporal patterns of methane fluxes across alpine permafrost region on the Tibetan Plateau Open
Methane (CH4) emissions from thawing permafrost could amplify climate warming. However, long-term trajectory of net CH4 balance in permafrost regions, particularly high-altitude permafrost regions, remains unknown. Based on literature synt…

Graphical representation of global water models Open
Numerical models are simplified representations of the real world at a finite level of complexity. Global water models are used to simulate the terrestrial part of the global water cycle, and their outputs contribute to the evaluation of i…

Assessment of climate mitigation potential of French grasslands using the land surface model ORCHIDEE-GM Open
There is now growing awareness that agricultural land use impacts climate not only through its GHG budget, but also through albedo-mediated changes of the surface energy budget. For instance, grasslands have higher surface albedo (i.e. mor…

Decoupling of soil carbon mineralization and microbial community composition across a climate gradient on the Tibetan Plateau Open
Soil microbes drive soil organic carbon (SOC) mineralization. Because microbial groups differ in metabolic efficiency and respond differently to temperature variation, it is reasonable to expect a close association of SOC mineralization an…

Analyzing Long-Term Land Use/Cover Change (LUCC) and PM10 Levels in Coastal Urbanization: The Crucial Influence of Policy Interventions Open
With the rapid acceleration of global urbanization, the impact of land use/cover change (LUCC) on the environment and ecosystems has become increasingly prominent, particularly in terms of air quality, which has emerged as a significant is…

Isotopic partitioning of gaseous nitrogen emissions of natural terrestrial ecosystems Open
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 flu…

Recent stabilization of agricultural non-CO2 greenhouse gas emissions in China Open
Agriculture emerges as a prominent contributor to CH4 and N2O emissions in China. However, estimates of these two non-CO2 greenhouse gases (GHGs) remain poorly constrained, hindering a precise understanding of their spatiotemporal dynamics…

Permafrost Region Greenhouse Gas Budgets Suggest a Weak CO<sub>2</sub> Sink and CH<sub>4</sub> and N<sub>2</sub>O Sources, But Magnitudes Differ Between Top‐Down and Bottom‐Up Methods Open
Large stocks of soil carbon (C) and nitrogen (N) in northern permafrost soils are vulnerable to remobilization under climate change. However, there are large uncertainties in present‐day greenhouse gas (GHG) budgets. We compare bottom‐up (…

Aspirational nitrogen interventions accelerate air pollution abatement and ecosystem protection Open
Although reactive nitrogen (Nr) emissions from food and energy production contribute to multi-dimensional environmental damages, integrated management of Nr is still lacking owing to unclear future mitigation potentials and benefits. Here,…
