Contrasting evolution of the Arabian Sea and Pacific Ocean oxygen minimum zones during the Miocene
Abstract Ocean oxygen minimum zones have expanded since the mid-20th century, yet their future remains uncertain. Previous studies show that the eastern tropical North Pacific was well oxygenated during the warm Miocene Climatic Optimum (17.0–14.8 Ma), suggesting better oxygenation under climatic…

Marine darkwave as an event-based framework to assess unusual periods of reduced underwater light availability
Abstract Episodic reductions in underwater light can be a key driver of marine ecosystem degradation. Yet a consistent event-based framework describing the frequency, duration and intensity of substantial but short-term reductions in underwater light does not exist. Here, we proposed marine…

High resolution US water table depth estimates reveal quantity of accessible groundwater
Abstract Groundwater is the largest accessible freshwater on Earth, yet its quantity and distribution remain unknown. Here, we develop a high-resolution (approximately 30 m) estimate of water table depth over the continental United States using machine learning that includes uncertainty. We…

Scenario-based forecast of the evolution of 75 years of unrest at Campi Flegrei caldera (Italy)
Abstract Campi Flegrei last erupted in 1538 and periods of increased seismicity, gas emission and ground deformation occurred in the 50’s, 70’s 80’s and are ongoing since 2005. The eventual culmination of the unrest in an eruption, would directly impact on 2 million people living in the region…

Substantial reduction of solar photovoltaic potential in China by an extreme dust event
Abstract Aerosols suspended in the atmosphere and deposited on solar panels reduce the solar power generation through dimming and soiling effects, respectively. Here we evaluate the impact of a six-day extreme dust event in March 2021 on the solar photovoltaic potential using an atmospheric…

Unveiling the large coverage of red snow algae blooms in antarctic coastal snowfields
Abstract Several locations across Antarctica are experiencing snow algal blooms on the surfaces of coastal snowfields, which significantly reduce surface albedo – by up to 20% – and consequently enhance the melting of snow and ice. Here we revealed the potential distribution of red snow algal…

Emerging outflow of not-so-dense shelf water from an East Antarctic polynya
Abstract East Antarctic coastal polynyas—semi-permanent areas of ice-free ocean—are vital for sea ice production, Antarctic Bottom Water formation, and global heat redistribution. The Dibble Polynya has pronounced sea-ice production, yet the shelf water properties there and its offshore influence…

Detrital zircon–apatite fingerprinting challenges glacial transport of Stonehenge’s megaliths
Abstract How Stonehenge’s building blocks arrived on Salisbury Plain remains debated, with glacial and human transport mechanisms proposed. Here we test the possibility of Pleistocene glacial sediment input using grain-scale U–Pb fingerprinting of detrital zircon and apatite from modern stream…

Field in the frame: measuring agricultural ponds
Freshwater ecosystems produce methane, a potent greenhouse gas, and ponds on agricultural land are particularly strong emitters. Dr Malerba and colleagues used maps of agricultural ponds and compiled data on their emissions to produce assessments of methane emissions from agricultural ponds for…

Continental river runoff enhances atmospheric aerosol formation over the Arctic Ocean
Abstract The formation of cloud condensation nuclei is a critical but uncertain factor in Arctic climate dynamics. A major nuclei contributor is new particle formation, yet the geographical variations in activity and the factors driving it remain poorly understood. Here, we present a nine-year…

Ship fuel sulfur content regulations may exacerbate mass coral bleaching events on the Great Barrier Reef
Abstract Global shipping fuel sulphur content regulations introduced in 2020 reduced the radiative cooling effects of sulfate aerosol over the ocean. Here we use the WRF-Chem model to estimate the effect these regulations have had on aerosols, clouds and solar radiation at the Great Barrier Reef…

Interfacial hydrodynamic isotope fractionation of infiltrating rainfall in soil pore water is independent of evaporation
Abstract Quantifying how rainwater infiltration modifies the stable isotope composition of soil pore water is essential for tracing water movement through the critical zone. We monitored intact soil columns under natural rainfall at high temporal resolution, jointly measuring seepage flux and the…

Carbon emissions along divergent plate boundaries modulate icehouse-greenhouse climates
Abstract The exchange of carbon between oceanic plates, the deep Earth, and the atmosphere plays a significant role in modulating global climate. Icehouse-greenhouse climate fluctuations have been attributed to changes in palaeogeography and solid Earth degassing, particularly along continental…

Climate change risk index and municipal bond disclosures of United States drinking water utilities
Abstract Climate change increases risks to the operations and financial reliability of drinking water utilities across the United States (US). Here we develop a comparative climate risk index that includes hazard, vulnerability, and exposure components for 1455 medium and large municipal US…

Recent giant detachment of a glacier on the Tibetan plateau provoked by its frozen tongue
Abstract Sudden detachments of entire glacier tongues are rare but potentially devastating events that remain poorly understood. Here, we report on an event that occurred in Tibet on November 1, 2022, with an ice volume of ~40 million cubic meters, ranking it among the largest recorded ice…

Global mapping of potential coastal compound flood risk at 0.1∘ resolution
Abstract Compound floods resulting from the concurrence of river overflow and elevated sea levels are becoming increasingly unpredictable as climate extremes intensify. However, most flood risk assessments still fail to account for the uncertainty in their co-occurrence. Here, we quantify potential…

Rewiring climate modeling with machine learning emulators
Abstract Earth system models, or simulators, are foundational for projecting climate change impacts, but their computational expense limits the number and diversity of simulations available. Machine learning-based emulators, statistical surrogates trained on simulator outputs, can replicate…

Climatic variability, vegetation dynamics, and cultural innovation in Southern Africa during the Middle Stone Age
Abstract Paleoenvironmental reconstructions in southern Africa have often relied on isolated or fragmentary records, limiting our understanding of ecosystem dynamics during the Middle Stone Age (c. 300–40 ka). Here, we reassess vegetation and climate change between Marine Isotope Stages (MIS) 5 and…

Minimal impact of recent decline in C4 vegetation abundance on atmospheric carbon isotopic composition
Abstract Changes in atmospheric carbon dioxide concentrations, climate, and land management influence the abundance and distribution of C3 and C4 plants, yet their impact on the global carbon cycle remains uncertain. Here, we use a parsimonious model of C3 and C4 plant distribution, based on…
