Treeline and Seasonal Sea ice meet today

Description: In the Pliocene, the Canadian Arctic was a contiguous land mass and forests reached to the Arctic ocean even on Ellesmere Island and Meighen Island. Some suggest that sea ice in the arctic was seasonal (in winter). So where do forests and winter sea ice meet today? Are these areas good analogs for the warm mid_Pliocene?
