A new sea ice reconstruction for the Barents Sea (Arctic) indicates "ice-free" conditions occurred during the Early Holocene .

Sea ice biomarker indicators suggest the highest sea ice extent occurred during the 20th century ("0 cal yr BP").

pdfs.semanticscholar.org/9d01/7c43133eb… "prolonged seasonal sea ice presence prevalent in the region today" and "extensive modern sea ice conditions (≈80% spring sea ice coverage)"

vs.

"ice-free conditions during the Early Holocene" (0-15% spring sea ice coverage)
