该研究的提出者、北极熊国际协会的首席科学家斯蒂芬·阿姆斯特拉普告诉法新社说:“在冰雪重新冻结、可以外出觅食前,北极熊面临着前所未有的超长禁食期。”
On current trends, the study concluded, polar bears in 12 of 13 subpopulations analyzed will have been decimated within 80 years by the galloping pace of change in the Arctic, which is warming three times as fast as the planet as a whole.
该研究得出结论称,按照目前的趋势,随着北极加速变暖,研究分析的13个北极熊亚种群将有12个在80年内灭绝。目前北极变暖速度是地球整体的三倍。
"By 2100, recruitment" — new births — "will be severely compromised or impossible everywhere except perhaps in the Queen Elizabeth Island subpopulation," in Canada's Arctic Archipelago, said Amstrup.
阿姆斯特拉普称,“到2100年,新生北极熊数量将会剧减甚至降为零,除了 That scenario foresees Earth's average surface temperature rising 3.3 degrees Celsius above the preindustrial benchmark. One degree of warming so far has triggered a crescendo of heatwaves, droughts and superstorms made more destructive by rising seas.
科学家预测,到那时地球的平均表面温度将比工业化前基准水平高出3.3摄氏度。变暖1度迄今为止已经引发日益严重的热浪、干旱和超级风暴,而海平面上升使得风暴更具破坏力。
