We conclude that the observed cooling over central Eurasia was probably due to a sea-ice-independent internally generated circulation pattern ensconced over, and nearby, the Barents–Kara Sea since the 1980s. — McCusker et al.

(Or, based on the abstract, maybe only 0.9 meters in ‘modern scale configuration’, but over 2 meters [2.9-4] in unspecified other configurations).
