Community involvement in planning and implementation and their benefits via local infrastructure and workforce development are key determinants of support for direct air capture of carbon dioxide in the United States, according to a focus group analysis and national survey data.
Microbial sulfur oxidation in the stream channel during periods of high flow, along with erosion, modulates carbonate weathering and carbon dioxide cycling in a rapidly uplifting catchment in Taiwan, according to combined analyses of riverine geochemistry and microbial communities.
The Southern Resident killer whale population will decline slowly for a generation or two before accelerating toward extinction, suggests a model-based population viability analysis accounting for sensitivities to age structure, survival rates, and prey-demography functional relationships.
If elevated ice-melt rates in the Amundsen Sea Embayment, West Antarctica, can be restored to present levels within 100 years, rates of ice discharge and the sea level contribution from the region can be limited, suggest sensitivity experiments with an ice sheet model.
Regions such as the United States, the Amazon and Southern Europe are hot spots in wildfire research, while Africa and Siberia with the largest burned areas are largely understudied, according to an analysis of more than 60,000 peer-reviewed articles over 1982-2022 using a large language model.
Irrigation, coupled with decreased precipitation and snowmelt in the Brahmaputra basin since 2003 outweigh the effects of increased precipitation in the Ganges basin over the same period, according to remote sensing data and land surface model reanalysis.
Afforestation strategies in optimal lands, with careful selection of forest types with high carbon sinks, can help increase carbon sequestration by 25% without adverse effects on food and land sustainability, according to an integrated assessment modelling framework.
The type of vehicles owned by Norwegians depends on household size, income and work commute, and battery electric vehicle ownership is concentrated in the wealthier part of the population, according to an analysis of socio-economic data of 2.4 million households from 2005 to 2022.
Coastline and metropolitan counties in the US show large spatial inequality of property flood risk linked to urban density and growth, economy, and racial and income segregation according to an analysis of flood risk and socio-economic data.
Sulfides nucleate early in magma evolution, persist through crystallization, then slowly resorb back into the melt once sulfur begins to degass, according to geochemical analyses of tephra from the 2014 to 15 Holuhraun eruption, Iceland
Ground surface warming and permafrost thaw projected under moderate and extreme scenarios threaten northern Canada’s land transportation infrastructure, according to a data-driven approach using an artificial intelligence scheme, reanalysis data, and regional climate projections.
Coastal wave heights in the Alaskan Arctic region are projected to increase as sea ice cover decreases and the open water season expands, leading to hazard exposure for up to three more months by 2070, according to simulations of an extratropical cyclone under low and high emissions pathways.
Analyses of a detailed microearthquake catalog highlights the complexity of the faults ruptured during the shallow 2020 Sparta North Carolina earthquake and identifies a likely nucleation point near the intersection of a reverse fault and a blind strike-slip fault.
Comprehensive accounting for consumptive water uses in the Colorado River Basin, United States indicates that irrigated agriculture consumes half of all river flows; nearly two-thirds of agricultural water goes to cattle feed crops.
The marine clamworm Perineresis vancaurica fragments expanded polystyrene foam and its gut bacteria, dominated by Acinetobacter and Ruegeria, enhance polystyrene degradation, according to analyses and incubation experiments conducted on samples collected around Xiamen Island, China.
After intense winter cooling 2012-2015, Labrador Sea convection continued to intensify to 2018, and subsequently weakened and shoaled due to polar vortex collapse and Arctic sea ice loss, as analyses of Argo-float and ship-based measurements show.
Financial professionals tend to worry less about climate change and to value carbon offsets less highly than climate experts; for them, economic aspects of climate mitigation outweigh environmental and social elements, according to an incentivized experiment and survey.
The magmatic rocks of the Antarctic Peninsula vary based on the timing of their formation in contrast with most other arcs worldwide which vary by spatial location, according to a compilation of existing and new geochemical and geochronological data.
