Sea ice retreat is opening up Arctic shipping routes, reducing transit times and enhancing access to regions with valuable resources. However, increased shipping has a negative impact on the Arctic ...

Winter Arctic sea ice concentration (SIC) variability reflects both anthropogenic warming and internal climate variability, but separating their Arctic signatures remains difficult. Here, we apply ...

New research indicates that black carbon pollution — the soot-like planet-warming material released through the incomplete burning of fossil fuels — has reached higher levels in the Arctic than ...

Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal erosion.
