The mechanisms underlying the deformation and eventual destruction of Earth’s cratons remain enigmatic, despite proposed links to subduction and deep mantle plume processes. Here we study the deformation of the North China Craton using four-dimensional mantle flow models of the plate–mantle system since the late Mesozoic, integrating constraints from lithospheric deformation, mantle seismic tomography and the evolution of surface topography. We find that flat-slab subduction induced landward shortening and lithospheric thickening, while subsequent flat-slab rollback caused seaward extension and lithospheric thinning. Both subduction phases resulted in substantial topographic changes in basin sediments. Rapid flat-slab rollback, coupled with a viscosity jump and phase change across the 660 km mantle discontinuity, was a key ingredient in shaping a large mantle wedge. We argue that craton deformation through lithospheric extension and thinning was triggered by the subduction of a flat slab and its subsequent rollback. The integration of data into mechanical models provides insights into the four-dimensional dynamic interplay involving subduction, mantle processes, craton deformation and topography. Mesozoic deformation of the North China Craton occurred via lithospheric thickening followed by thinning and extension triggered by flat-slab subduction and rollback, according to four-dimensional mantle flow models of the plate–mantle system.

The processes that control the deformation and eventual destruction of Earth’s oldest continental crust are unclear. Mantle flow models suggest subduction played a role in the deformation of the North China Craton.

Since the 1970s, Arctic sea ice has undergone unprecedented change, becoming thinner, less extensive and less resilient to summer melt. Snow’s high albedo greatly reduces solar absorption in sea ice and the upper ocean, which mitigates sea–ice melt and ocean warming. However, the drivers of summertime snow depth variability are unknown. The Arctic Oscillation is a mode of natural climate variability, influencing Arctic snowfall and air temperatures. Thus, it may affect summertime snow conditions on Arctic sea ice. Here we examine the role of the Arctic Oscillation in summer snow depth variability on Arctic sea ice in 1980–2020 using atmospheric reanalysis, snow modelling and satellite data. The positive phase leads to greater snow accumulation, ranging up to ~4.5 cm near the North Pole, and higher surface albedo in summer. There are more intense, frequent Arctic cyclones, cooler temperatures aloft and greater snowfall relative to negative and neutral phases; these conditions facilitate a more persistent summer snow cover, which may lessen sea-ice melt and ocean warming. The Arctic Oscillation influence on summertime snow weakens after 2007, which suggests that future warming and Arctic sea-ice loss might modify the relationship between the Arctic Oscillation and snow on Arctic sea ice. Summer snow accumulation and its albedo effect on Arctic sea ice are controlled by the Arctic Oscillation atmospheric circulation pattern, according to a combined modelling and remote sensing analysis.

A re-evaluation of global land-to-ocean carbon exports using a multi-model ensemble and a database of observations reveals that the export of carbon by rivers is 20% higher than that reported in the 2021 Intergovernmental Panel on Climate Change (IPCC) assessment. These findings underscore the important contribution of riverine carbon to the carbon budget.

Rivers are a key component of the global carbon cycle. They receive vast quantities of terrestrial carbon, of which a large fraction is ultimately exported to the coastal ocean. Our review of previously published assessments reveals that substantial uncertainties remain with regard to the spatial distribution and speciation of the carbon export. Accurate quantification of the relative contributions of dissolved, particulate, organic and inorganic carbon to the total amounts is, however, of crucial importance for the coupling between the terrestrial and marine carbon cycles. Breaking down existing spatially explicit assessments over large river basins, we find a disagreement in flux estimates that exceeds two orders of magnitude for more than half of the basins. Using machine-learning techniques in combination with a multi-model ensemble and an updated database of observations, we overcome the inconsistencies in existing assessments and narrow down uncertainties in riverine carbon exports. Our revised assessment yields a global riverine export of 1.02 ± 0.22 (2σ) PgC yr−1. This carbon flux is partitioned into 0.52 ± 0.17, 0.30 ± 0.14, 0.18 ± 0.04 and 0.03 ± 0.02 PgC yr−1 of dissolved inorganic, dissolved organic, particulate organic and particulate inorganic carbon, respectively. We estimate the carbon contribution through groundwater export to be minor (0.016 PgC yr−1). Our assessment suggests an underestimation of the land-to-ocean carbon flux by 0.24 PgC yr−1 by the Intergovernmental Panel on Climate Change (IPCC) and calls for a revision of the oceanic carbon budget. Global riverine carbon export to the ocean may exceed previous estimates, underscoring the important role of riverine carbon to the carbon budget, according to a multi-model ensemble assessment constrained by a global dataset.
河流是全球碳循环的重要组成部分。它们接收了大量的陆地碳，其中很大一部分最终被输出到沿岸海洋。我们对以前公布的评估结果进行了回顾，发现在碳输出的空间分布和种类方面仍然存在很大的不确定性。然而，准确量化溶解碳、颗粒碳、有机碳和无机碳对总量的相对贡献，对陆地碳循环和海洋碳循环之间的耦合至关重要。对现有的大河流域空间明确评估进行细分后，我们发现在一半以上的流域中，通量估计值的差异超过了两个数量级。利用机器学习技术，结合多模型集合和最新的观测数据库，我们克服了现有评估中的不一致性，缩小了河流碳输出的不确定性。我们修订后的评估得出全球河流碳输出量为 1.02 ± 0.22 (2σ) PgC yr-1。该碳通量分别为 0.52 ± 0.17、0.30 ± 0.14、0.18 ± 0.04 和 0.03 ± 0.02 PgC yr-1 的溶解无机碳、溶解有机碳、颗粒有机碳和颗粒无机碳。我们估计通过地下水输出的碳贡献很小（0.016 PgC yr-1）。我们的评估表明，政府间气候变化专门委员会（IPCC）低估了陆地到海洋的碳通量 0.24 PgC yr-1，并呼吁修订海洋碳预算。

A global analysis of post-fire vegetation productivity recovery reveals that the recovery time shows spatial variations across vegetation types and regions. The dominant factors that influence the recovery time in the majority of the global burned area are the post-fire climate conditions, such as soil moisture, vapour pressure deficit and air temperature.

This study investigates the history of graphitic carbon in two ancient North American mountain belts related to Nuna supercontinent assembly. Using rhenium–osmium and uranium–lead dating, the research reveals that biogenic graphite was hydrothermally remobilized in shear zones during late orogenesis, indicating periodic carbon cycling over 200 million years.

Wildfire activity in Arctic and boreal regions is rapidly increasing, with severe consequences for climate and human health. Regional long-term variations in fire frequency and intensity characterize fire regimes. The spatial variability in Arctic–boreal fire regimes and their environmental and anthropogenic drivers, however, remain poorly understood. Here we present a fire tracking system to map the sub-daily evolution of all circumpolar Arctic–boreal fires between 2012 and 2023 using 375 m Visible Infrared Imaging Radiometer Suite active fire detections and the resulting dataset of the ignition time, location, size, duration, spread and intensity of individual fires. We use this dataset to classify the Arctic–boreal biomes into seven distinct ‘pyroregions’ with unique climatic and geographic environments. We find that these pyroregions exhibit varying responses to environmental drivers, with boreal North America, eastern Siberia and northern tundra regions showing the highest sensitivity to climate and lightning density. In addition, anthropogenic factors play an important role in influencing fire number and size, interacting with other factors. Understanding the spatial variability of fire regimes and its interconnected drivers in the Arctic–boreal domain is important for improving future predictions of fire activity and identifying areas at risk for extreme events. Arctic–boreal biomes vary regionally in the sensitivity of their fire regime to climate, according to an analysis of properties of individual fires measured by satellite radiometry.
