We reconstructed glacier-wide mass balance (MB) for five large glaciers (area ≥ 100 km2) across the Karakoram and Himalaya from 1950 to 2022 using a temperature-index model, calibrated with geodetic MBs (2000–2019) and validated against independent MB estimates. Mean annual MBs ranged from near equilibrium in the Karakoram (≈0.01 m w.e. a−ˡ for Baltoro and Siachen) to substantial losses in the Himalaya (−0.22 to −0.83 m w.e. a−ˡ for Bara Shigri, Gangotri, and Zemu). Mass turnover was low in the Karakoram (0.08–0.18 m w.e. a−ˡ) and considerably higher in the Himalaya (0.58–0.94 m w.e. a−ˡ). MB of Karakoram glaciers (Baltoro, Siachen) is primarily controlled by summer snowfall and summer temperature, Himalayan glaciers (Bara Shigri, Gangotri) by winter snowfall and summer temperature, and Zemu Glacier by winter snowfall and both summer and winter temperatures. Sensitivity to climatic forcing was significantly higher in the Himalaya than in Karakoram. All glaciers exhibited accelerated mass loss after 2000 (≈17–267%), coincident with rising temperatures and declining precipitation, demonstrating strong regional contrasts in glacier–climate interactions.
我们利用温度指数模型重建了1950年至2022年喀喇昆仑和喜马拉雅地区5个大型冰川（面积 ≥ 100 km2）的全冰川质量平衡（MB），该模型采用大地测量MB（2000-2019）校准，并根据独立的MB估计进行了验证。平均年mbbs范围从喀喇昆仑的接近平衡（Baltoro和Siachen≈0.01 m w.e. a−↓）到喜马拉雅的大量损失（Bara Shigri、Gangotri和Zemu的- 0.22至- 0.83 m w.e. a−↓）。喀喇昆仑山脉的物质周转量较低（0.08-0.18 m w.e. a−↓），而喜马拉雅山脉的物质周转量较高（0.58-0.94 m w.e. a−↓）。喀喇昆仑冰川（Baltoro、Siachen）的MB主要受夏季降雪和夏季温度的控制，喜马拉雅冰川（Bara Shigri、Gangotri）的MB主要受冬季降雪和夏季温度的控制，而泽木冰川的MB主要受冬季降雪和夏季和冬季温度的控制。喜马拉雅地区对气候强迫的敏感性显著高于喀喇昆仑地区。所有冰川在2000年之后都呈现出加速的质量损失（≈17-267%），与温度上升和降水减少相一致，显示出冰川-气候相互作用的强烈区域差异。

Few glaciers remain in the Mediterranean region: those that do have mostly retreated well into cirques, persisting as small, isolated glaciers or ice patches. In this study, we found that summer temperatures in the Mediterranean region have risen dramatically since the 1970s with the average increasing by >1.9 °C by 2024 relative to the 1991–2020 mean. Winter precipitation in the Mediterranean region has shown a statistically significant slight declining trend over the last 75 years. From 2019 to 2023, snow cover duration declined across most of the Mediterranean. The North Atlantic Oscillation (NAO) has a limited influence on glacier mass balance and snowpack in the Mediterranean based on results of regression analysis. This is because the dominant control on mass balance change in the Mediterranean is summer temperature rather than precipitation, much more so than further north in Europe where NAO has more influence on glaciers. However, local topoclimate factors mitigate the summer temperature impact allowing the paradox of glacier survival in niche settings in some of the wettest Mediterranean regions. Most Mediterranean glaciers only survive high summer temperatures because of excess snow accumulation by avalanching snow, highlighting the key influence of local topoclimatic conditions on glacier survival in the Mediterranean region. The fact that Mediterranean glaciers only survive because of high accumulation but are also strongly affected by changes in summer temperature, accords with the global observation that warm-wet glaciers are more sensitive to changing temperature than cold-dry glaciers. Understanding how glaciers and snowpack respond to climate change in the Mediterranean mountains has relevance beyond this region and provides an important comparison for other mid-latitude regions where glaciers and snowpack are crucial for water supply.

Net primary productivity (NPP) is a fundamental component of global carbon cycling. However, the global partitioning between aboveground (ANPP) and belowground NPP (BNPP) remains poorly quantified, which limits our understanding of carbon allocation strategies and ecosystem responses to environmental change. In this study, a resource-constrained framework was developed to consistently estimate ANPP and BNPP from resource constraints (e.g., light, water, and nutrient). Model performance was evaluated using 937 field observations from 1939 to 2014, including 252 paired ANPP and BNPP records, achieving Nash–Sutcliffe efficiency (NSE) values of 0.76 for ANPP, 0.49 for BNPP, and 0.52 for total NPP. The framework estimated global ANPP and BNPP at 25.36 and 22.01 Pg C yr−1, respectively, with BNPP accounting for about 46.5% of total productivity. Across biomes, long-term mean ANPP ranged from 129 to 1088 g C m−2 yr−1, and BNPP from 153 to 781 g C m−2 yr−1. Further analysis using an interpretable machine learning approach revealed that temperature was identified as the dominant control of fBNPP (BNPP/NPP) in forests, while vapor pressure deficit and aridity index were most influential in non-forest ecosystems. Our findings provide consistent assessment of above- and belowground NPP partitioning. These results support the resource-constrained framework as a robust and ecologically interpretable tool for simulating NPP partitioning, which helps improve the representation of carbon allocation in terrestrial biosphere models and enhances our understanding of ecosystem responses to a change climate.
净初级生产力（NPP）是全球碳循环的一个基本组成部分。然而，全球范围内的地上NPP （ANPP）和地下NPP （BNPP）之间的划分仍然缺乏量化，这限制了我们对碳分配策略和生态系统对环境变化的响应的理解。在本研究中，开发了一个资源约束框架，以从资源约束（如光、水和营养）中一致地估计ANPP和BNPP。利用1939 - 2014年的937个野外观测数据（包括252个配对的ANPP和BNPP记录）对模型性能进行了评估，得到ANPP的Nash-Sutcliffe效率（NSE）值为0.76，BNPP为0.49，总NPP为0.52。该框架估计全球ANPP和BNPP分别为25.36和22.01 Pg C yr - 1， BNPP约占总生产力的46.5%。各生物群系的长期平均ANPP在129 ~ 1088 g C m−2 yr−1之间，BNPP在153 ~ 781 g C m−2 yr−1之间。利用可解释机器学习方法的进一步分析表明，温度被确定为森林中fBNPP （BNPP/NPP）的主要控制因素，而蒸汽压赤字和干旱指数在非森林生态系统中影响最大。我们的研究结果提供了对地上和地下NPP划分的一致评估。这些结果支持资源约束框架作为模拟NPP分配的可靠且生态可解释的工具，有助于改善陆地生物圈模型中碳分配的代表性，并增强我们对生态系统对气候变化的响应的理解。
