Description:Arctic sea ice is an important part of the climate system. Its higher albedo reflects much of the incoming solar radiation during the summer, keeping the region cooler than an ice-free environment. The sea ice cover acts as a physical barrier between the ocean and the atmosphere, limiting energy and moisture exchange. Ice formation and melt substantially modify the biogeochemical balance of the upper ocean. Sea ice also acts as a platform for charismatic megafauna and other components of the ecosystem. Finally, it is both a facilitator and hazard to human activities in the Arctic. In 2020, the Arctic sea ice cover continued the declining trends in extent, thickness, and volume.
