Plastic pollution is now pervasive in the Arctic, even in areas with no apparent human
activity, such as the deep seafloor. In this Review, we describe the sources and impacts of …

The Arctic climate system is rapidly transitioning into a new regime with a reduction in the
extent of sea ice, enhanced mixing in the ocean and atmosphere, and thus enhanced …

Intense cyclones driving extreme Arctic weather and climate events have been more
frequently observed during recent years, causing dramatic environmental and …

Arctic cyclones are an extremely common, year-round phenomenon, with substantial
influence on sea ice. However, few studies address the heterogeneity in the spatial patterns …

The Arctic's rapid sea ice decline may influence global weather patterns, making the
understanding of Arctic weather variability (WV) vital for accurate weather forecasting and …

Synoptic-scale cyclones in the Arctic are an important source of short-term sea ice variability
during the melt season. This study examines whether recent changes to the Arctic …

Understanding the location and intensity of hazardous weather across the Arctic is important
for assessing risks to infrastructure, ship**, and coastal communities. Key hazards driving …

Fresh water plays a pivotal role in the Arctic Ocean's climate, as salinity governs upper
ocean stratification, convection, and the promotion of seasonal sea ice growth or melt. The …

Arctic cyclones are the most energetic weather systems in the Arctic, producing strong winds
and precipitation that present major weather hazards. In summer, when the sea ice cover is …

We perform a climatological analysis of summer‐time Arctic cyclone structure in reanalysis
data using a phase space approach. A classification scheme for Arctic cyclones is proposed …
