生物多样性的消失率很惊人，比因自然因素灭绝的速度要高上1,000 到10,000倍。 （《皇家学会哲学会刊B辑：生物学》〔Philosophical Transactions of the Royal Society B (Biological Science)〕） 由于各国无法达成保护动植物生命的目标，生态系统可能朝向永久性的损害。 （联合国环境规划署〔UNEP〕，2010年） 目前每天高达270种独特的物种在消失。. 由于气候变迁以及其他大部分的人为因素，有些专家说，地球将经历「第6次大灭绝」。 当全球平均气温上升超过摄氏3.5度，全球各地高达70%的物种可能会灭绝。（联合国跨政府气候变迁小组） 2010年各物种受影响的最新报导：
由于海冰减少，自1975年以来，南极企鹅数量锐减80%以上。
由于气候变迁造成过早解冻或结冰，植物性食物无法取得，北极驯鹿因此纷纷饿死，其数量正急遽下降当中。
2010年9月，数万只海象由于缺乏平常休憩的海冰，不寻常地都跑上岸来，这种情况在2007年和2009年也发生过。
候鸟们纷纷死亡，因为不合时宜的旅行，使他们到达目的地时没有足够的食物可吃，例如湿地已经干涸，不再能提供他们栖息地。 参考来源
