Roadways provide safe and efficient transport and are essential to the function of societies and economies. However, climate change increasingly pushes pavements beyond their engineering limits, leading to deterioration. In this Review, we explore the impacts of climate change on roadways and approaches to mitigate them. Roadways are vulnerable to changes in temperature, precipitation and sea level rise driven by climate change. High temperatures soften asphalt pavements, causing rutting, which is projected to increase by 2% per 1% increase in mean temperature. Increased moisture in the underlying soil caused by precipitation and sea level rise reduces the load-bearing capacity of roadways for months and in some cases halves their lifetime. Roadway closures due to extreme weather events or resulting reconstruction cause delays and detours; by 2100, high tide flooding in the USA is expected to cause delays of 3.4 billion vehicle-hours per year. Climate change is projected to increase national annual costs of pavement maintenance by over US$500 million on average by 2050, depending on the country. Adaptation strategies include adjusting the type of asphalt, reinforcing concrete with steel, stabilizing gravel roads and adding nature-based features. Rapid implementation of policies, guidance on evaluating adaptation alternatives and exploration of the combined impacts of multiple climate stressors are needed. Roadways are damaged by temperature extremes, increased precipitation and sea level rise. This Review discusses the mechanisms and impacts of climate stressors on roadways, the resulting operational and maintenance challenges, and strategies to increase resilience.

Extreme and compound events disrupt lake ecosystems worldwide, with their frequency, intensity and duration increasing in response to climate change. In this Review we outline evidence of the occurrence, drivers and impact of extreme and compound events in lakes. Univariate extremes, which include lake heatwaves, droughts and floods, underwater dimming episodes and hypoxia, can occur concurrently, sequentially or simultaneously at different locations to form multivariate, temporal or spatial compound events, respectively. The probability of extreme and compound events is increasing owing to climate warming, declining lake water levels in half of lakes globally, and basin-scale anthropogenic stressors, such as nutrient pollution. Most in-lake extreme events are inherently compound in nature owing to tightly coupled physical, chemical and biological underlying processes. The cascading effects of compound events propagate or dissipate through lakes. For example, a heatwave might trigger stratification and oxygen depletion, subsequently leading to fish mortality or the proliferation of harmful algal blooms. Interactions between extremes are increasingly observed and can trigger feedback loops that exacerbate harmful algal blooms and fishery declines, leading to severe ecological and socio-economic consequences. Managing the increasing risk of compound events requires integrated models, coordinated monitoring and proactive adaptation strategies tailored to the vulnerabilities of lake ecosystems. Extreme and compound events in lakes are increasing in severity and frequency in response to climate change and basin-scale anthropogenic stressors. This Review explores the occurrence, drivers and impact of such events, focusing on their physical and ecological drivers, impacts and management responses.

Continental crust is fundamental to planetary habitability, providing the geochemical reservoirs and physical interfaces that drive and regulate exchanges among the atmosphere, hydrosphere and biosphere. However, the evolution of Earth’s crust is uncertain owing to debate regarding the competing roles of internal versus external energetic drivers. In this Review, we examine the interplay between internal and external drivers of the production, modification and destruction of crust on the early Earth using geochemical, geological and geophysical data. Internal drivers are potentially linked to plate tectonics and processes such as subduction (dripping) or delamination. External drivers from large meteorite impacts likely influenced crust formation by inducing rapid decompression melting of the mantle to form basaltic protocratons, the early, mantle-derived crustal nuclei that preceded stable continental crust. On a planet covered by water, protocratons might have been transformed by intracrustal differentiation into evolved (continental) crust. Future research into the processes driving Earth’s early evolution and habitability should consider a wide range of temporal and spatial scales from seconds to millions of years and the subgrain to the galactic, to uncover the long-wavelength patterns, in mantle overturn rates and impact flux preserved in deep-time records. Continental crust is important for Earth’s habitability. This Review explores how the formation and stabilization of Earth’s early continental crust was modulated by internal and external factors such as subduction and bolide impacts, respectively.

Atmospheric nitrous oxide (N2O) is a potent greenhouse gas and ozone-depleting substance. In this Review, we outline global N2O sources, with a focus on hotspots and hot moments, and discuss strategies to mitigate N2O emissions. N2O can be released by natural sources such as bedrock weathering, but anthropogenic sources such as agriculture account for 40% of total emissions. Hotspots are localized regions of high emissions and include cropland soils (2.1 Tg N yr−1), tropical forests (1.55 Tg N yr−1), pasture soils with animal waste return (1.7 Tg N yr−1), and streams and small lakes (0.4 Tg N yr−1). Brief periods of intense emissions, known as hot moments, include post-deforestation, upland soils after fertilizer application, and desert and grasslands after precipitation. N2O production from terrestrial and aquatic environments is mainly driven by two microbial processes: nitrification and denitrification. Bioaugmentation and biogeoengineering technologies hold potential for reducing N2O emissions; for example, nature-based anammox hotspot geoengineering in Jiaxing, China, reduces N2O emissions by 27.1%. However, the spatiotemporal heterogeneities and different production pathways of N2O emissions are poorly represented in existing models, hindering the quantification and mitigation of emissions. A global N2O database is needed to address this limitation. Additionally, artificial intelligence technology could enable real-time agricultural management to align nitrogen supply with crop demand. Nitrous oxide (N2O) emissions are continuously increasing owing to human activities. This Review discusses the temporal and spatial variability of N2O sources, N2O production pathways, and the potential of biogeoengineering strategies in agricultural soils and terrestrial water bodies to mitigate emissions.
大气中的一氧化二氮(N2O)是一种强有力的温室气体和臭氧消耗物质。在这篇综述中,我们概述了全球N2O来源,重点关注热点和热点时刻,并讨论了减少N2O排放的策略。N2O可以通过基岩风化等自然来源释放,但农业等人为来源占总排放量的40%。热点是高排放的局部区域,包括农田土壤(2.1 Tg N yr - 1)、热带森林(1.55 Tg N yr - 1)、有动物粪便返回的牧场土壤(1.7 Tg N yr - 1)、溪流和小湖泊(0.4 Tg N yr - 1)。短时间的高排放,被称为热时刻,包括森林砍伐后,施肥后的高地土壤,以及降水后的沙漠和草原。陆地和水生环境中N2O的产生主要由两个微生物过程驱动:硝化和反硝化。生物强化和生物地球工程技术具有减少一氧化二氮排放的潜力;例如,中国嘉兴基于自然的厌氧氨氧化热点地球工程减少了27.1%的一氧化二氮排放。然而,在现有的模型中,N2O排放的时空异质性和不同的产生途径没有得到很好的体现,阻碍了排放的量化和减缓。需要一个全球性的N2O数据库来解决这一限制。此外,人工智能技术可以实现实时农业管理,使氮供应与作物需求保持一致。由于人类活动,一氧化二氮(N2O)的排放量正在不断增加。本文讨论了农业土壤和陆地水体中N2O来源的时空变异性、N2O产生途径以及生物地球工程策略的潜力。
