claimArctic sea ice is a major determinant in the movement and distribution of Mandt's black guillemot during the non-breeding season.
claimThe decline in the area, thickness, and seasonal duration of Arctic sea ice over the last 20 years has significantly altered the Arctic ecosystem, a trajectory predicted to continue as northern-latitude temperatures rise due to anthropogenic carbon emissions.
referenceA 2015 study by Hamilton et al. documented behavioral responses of ringed seals to declining Arctic sea-ice.

referenceGarcia-Soto et al. conducted a review and revision of global trends in physical and chemical aspects of the ocean using seven indicators: sea surface temperature, sea level, heat content, ocean pH value, dissolved oxygen concentration, Arctic sea ice extent/volume/thickness, and the magnitude of the Atlantic meridional overturning circulation.
measurementThe average Arctic sea ice extent in March 1979 was 16.3 million km2, which decreased to 14.4 million km2 by March 2023.
measurementThe average Arctic sea ice extent in September 1979 was 7.1 million km2, which decreased to 4.37 million km2 by September 2023.
referenceGarcia-Soto et al. (2021) provided an overview of ocean climate change indicators, including sea surface temperature, ocean heat content, ocean pH, dissolved oxygen concentration, arctic sea ice extent, thickness and volume, sea level, and the strength of the Atlantic Meridional Overturning Circulation (AMOC).
claimArctic sea ice typically reaches its maximum level around March and its minimum level in September.
claimPolar amplification, driven by rising global temperatures, is causing Arctic temperatures to increase faster than the rest of the planet, resulting in annual decreases in both maximum and minimum sea ice extent.

claimMelting Arctic sea ice contributes to changes in ocean circulation patterns, which may slow down or disrupt the thermohaline circulation and lead to regional changes in climate and ocean productivity.
