Land or swamp? edit: That wasn't meant to be derogatory. AFAIK large parts of that land will be swamp and mud if the permafrost thaws up. Even now there are large parts with no streets or railways, reachable only by treks over frozen rivers during winter, by sea if coastal, or air. And the infrastructures built on permafrost will suffer too, if it thaws up. The same way as large parts of Alaska and Canada are.
