Articles in Nature Climate Change and Geophysical Research Letters explore the impacts of atmospheric rivers on Arctic and Antarctic sea ice variability.
The 2023 Kahramanmaraş earthquakes occurred on active faults that were known to be a high seismic hazard, yet the devastating impacts of these earthquakes show that the risk was not adequately considered. Vulnerabilities arising from exposure, corruption and poverty led to a lack of seismic preparedness which amplified the earthquake risk into a tragic disaster.
Mackenzie Fiss explains how Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) is used for analyzing diverse dissolved organic matter mixtures, like those from salt marshes.
Grisel Jiménez Soto discusses how forward stratigraphic models can simulate the various sedimentary processes that control the geometry and distribution of sedimentary layers.
An article in Tectonics identified asymmetric rifting during the break-up of Gondwana from variations in a thermal lithosphere–asthenosphere boundary model for the South American and African passive margins.
An article in Journal of Volcanology and Geothermal Research explores the stratigraphy of eruptive deposits from Corbetti Caldera, Ethiopia, to gain insights into the eruption frequency and hazard.
An article in Molecular Ecology describes the factors shaping microbial eukaryotic populations and their role in the carbon cycle at deep-sea hydrothermal vents.
Feedbacks between chemical, physical, and biological processes at rift zones evolve through various time (seconds to 107 yrs) and spatial (microns to 106 m) scales. Consideration of these scales is needed to tap rift energy, water, and mineral resources safely and equitably while preserving biodiversity in these changing settings.
Drilling into the uppermost mantle through a complete section of intact ocean crust, formed at a fast-spreading mid-ocean ridge, would liberate fundamental knowledge into Earth processes. The activities and achievement will also inspire future generations of geoscientists, who are essential to adapt to climate change and deliver the energy transition.
International researchers flock to study the East African Rift, but local researchers and monitoring facilities are often overlooked. Nature Reviews Earth & Environment speaks to Atalay Ayele, Head of the seismology unit at the Institute of Geophysics, Space Science and Astronomy at Addis Ababa University, Ethiopia, about the challenges and potential of local seismic monitoring at the East African Rift.
Flexible decision-making tools are needed to support action plans for plastics and other pollutants. Reproducible Analytical Pipelines (RAPs) and technological readiness levels (TRLs) will enable systematic validation and global harmonization of plastic pollution monitoring methods.
Global CO2 emissions for 2022 increased by 1.5% relative to 2021 (+7.9% and +2.0% relative to 2020 and 2019, respectively), reaching 36.1 GtCO2. These 2022 emissions consumed 13%–36% of the remaining carbon budget to limit warming to 1.5 °C, suggesting permissible emissions could be depleted within 2–7 years (67% likelihood).
An article in Environmental Research Letters models the impact of climate change on future trends in hazardous driving conditions along two important transport systems within the Arctic–Boreal region.
