The simulated impact of the Atlantic meridional rescinding circulation on the low-frequency irregularity of the Arctic surface air temperature and sea ice degree is studied with a 1000-year-long segment of a control simulation of the Geophysical Fluid Dynamics Laboratory Climate Model version 2. 1. When the AMOC index leads by one year, the optimum anticorrelation with the Arctic sea ice level and the optimum connection with the Arctic SAT occur. The current declining trend in the satellite-observed sea ice degree also shows a similar pattern in the Atlantic sector of the Arctic in the wintertime, suggesting the opportunity of a role of the AMOC in the recent Arctic sea ice decline along with anthropogenic greenhouse-gas-induced warming.
