Arctic biodiversity is under threat from both climate-induced environmental change and anthropogenic activity. However, the rapid rate of change and the challenging conditions for studying Arctic environments mean that many […]
Lichens play important roles in habitat formation and community succession in polar and alpine ecosystems. Despite their significance, the ecological effects of lichen traits remain poorly researched. We propose a […]
In this study, we investigate the complex relationship between western disturbances (WDs), the El Niño–Southern Oscillation (ENSO), and extreme precipitation events (EPEs) in the western Himalaya (WH) during the extended […]
Diatom resting stages can remain viable in sediments for decades and germinate when exposed to suitable environmental conditions, inoculating the water column and the surface sediments with new populations of […]
Permafrost is a potentially important source of deglacial carbon release alongside deep-sea carbon outgassing. However, limited proxies have restricted our understanding in circumarctic regions and the last deglaciation. Tibetan Plateau […]
Microorganisms have traditionally accelerated the study of ecology and evolution owing to their relatively short generation times and astronomical population sizes. Indeed, their potential in helping us to understand the […]
The number of cryptotephra (non-visible volcanic ash) records from northeastern North America is unique in the continent. The resulting tephrostratigraphic framework includes ash deposits sourced from volcanic arcs across the […]
Antarctic ice cores can help determine ice mass loss from the Antarctic Ice Sheet (AIS) during past warm periods. We compile Last Interglacial (LIG) δ18O measurements from eight Antarctic cores […]
The Antarctic Circumpolar Current reduces the oceanographic transport of organisms from adjacent temperate ecosystems southward. Additionally, the extreme environmental conditions in the Antarctic marine environment, in particular south of the […]
The mesosphere and lower thermosphere (MLT) comprise a highly variable region that forms the transition region between the middle and upper atmosphere. The variability of this region is driven by […]
The Marine Ice Sheet–Ocean Model Intercomparison Project – phase 2 (MISOMIP2) is a natural progression of previous and ongoing model intercomparison exercises that have focused on the simulation of ice-sheet […]
We observe the evacuation of 11-year-old landfast sea ice in the Larsen B embayment on the East Antarctic Peninsula in January 2022, which was in part triggered by warm atmospheric […]
