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).

Isamar Cortés discusses how Python-based open-source software can be used to process satellite data.

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.

Margaret Cramm explains how quantitative stable isotope probing is used to understand microbial activities in the environment.

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.

Igor Pessoa describes how past environmental conditions can be inferred by measuring trace metals in coral skeletons.

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.

Mariana Gómez-Nicolás describes how coastal groundwater discharge zones can be mapped with electrical resistivity.

Steven Franke explains how high-resolution radio-echo sounding (RES) data enable the reconstruction of past ice sheet behaviour.

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 Global Change Biology investigates the relationship between extreme negative anomalies of vegetation growth and climate extremes.

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.

An article in Journal of Climate documents the changing occurrence of compound tropical cyclone–heatwave events in southeastern China.

An article in Geomorphology examines the relationship between wildfires and post-fire debris flows in Southern California.

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.

GeoSPACE is addressing the barrier of inaccessible field courses with a planetary mission approach, combining online participation with accessible in-person field work.

Chronic illnesses, mental health issues, and other hidden disabilities can be debilitating, especially in combination with stigmatization and lack of proper accommodations. Breaking barriers in academic systems for those with hidden disabilities demands that personal, institutional and organizational ableist biases are overcome, writes Isabel Carrera Zamanillo.

Earth is polluted with plastic waste, with impacts on ecosystems and health. This Issue and online Collection bring together research on plastic in the environment and discussion on how to combat this growing problem.
