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.
The textile industry has tried to combat the criticism of fast fashion through overly simplistic solutions at the product and operational level. Fast fashion cannot be fixed — the industry needs to be reconstructed to emphasize long material and product lifetimes.
An article in Geochemistry, Geophysics, Geosystems uncovers the source, distribution, and concentration of rare earth elements, yttrium and scandium in sea-floor sediments within the South Pacific Gyre.
Microorganisms and minerals both contribute to organic carbon preservation and accumulation in soil. The soil microbial carbon pump describes the microbial processes, but a separate soil mineral carbon pump needs to be acknowledged and investigated.
An article in Global Environmental Change documents the time of, and spatial variability in, transgression of the nitrogen and phosphorus planetary boundaries.
An article in Earth & Planetary Science Letters finds that post-collisional granites can be derived from a modified primary mantle source, rather than recycled lower crust.
An article in JGR Solid Earth explores the events of the 2018 Kīlauea eruption to assess the hazards posed by magma stored and transported quickly through volcanic flanks.
GeoSPACE is addressing the barrier of inaccessible field courses with a planetary mission approach, combining online participation with accessible in-person field work.
Representation and discrimination of those with mobility and sensory impairments is a serious problem in academia, especially in the Earth sciences. Non-disabled academics must fight prejudice and increase the support to, and visibility of, physically impaired colleagues, states Paul Upchurch.
