Further exacerbating the problem, the disappearance of Arctic sea-ice has triggered a rush to secure newly accessible resources, particularly fossil fuels, which are a primary cause of global warming. (It has even revived efforts to find the wreckage of Franklin’s lost ships.)
更棘手的是北极海冰消融引发了争夺新的可利用资源、特别是化石燃料的浪潮，而全球变暖主要就是由化石燃料导致的。（人们甚至重新试图寻找富兰克林失踪船只的残骸。）
