极端天气事件变得越来越严重,次数越来越频繁。12,13 (联合国跨政府气候变迁小组,2007年) 2010年重大灾难事件: 俄罗斯热浪和大火:
2010年夏天的热浪以及森林大火造成的空气污染,使得莫斯科的每天死亡人数倍增到700人。14,15 (俄罗斯科学院〔Russian Academy of Sciences〕) 莫斯科市政府官员宣称在过去的这个夏季,死亡率增加了60%,将近11,000个居民由于烟雾过量和创纪录的高温影响而丧生。16 巴基斯坦洪灾: 该国历史上最严重的大洪水,导致两千多人死亡,两千多万人受伤或无家可归,五分之一的国土泡在水中。17 中国土石流: 全国各地发生水灾和土石流,单单在 2010这一年,即造成超过3,100人死亡,一千多人失踪。自 1950年以来,洪水在中国增加了7倍。18 巴西 在2010年4月和6月,也发生了极端严重的水灾,每次皆有数百人死亡。19 波兰 在2010年5 月,遭受了几十年来最严重的水灾。20 2010年夏天,森林大火肆虐葡萄牙 ,这是受到低湿度、强风和摄氏40度的创纪录高温所引发。 21 2010年在乍得 和尼日尔利亚 ,干旱和洪水接连发生,洗劫了旱灾过后已所剩无几的粮食作物。 22 2010年,印度、北欧、北美和南美遭受极端酷寒和暴风雪 。 2010年,印尼、冰岛、土耳其、智利、海地等国因许多地震和火山爆发 而陷入混乱。. 全球暖化可能会导致像冰岛的埃亚菲亚德拉火山( Eyjafjallaj_kull)这类有冰层覆盖的火山更容易爆发,因为冰层融化会造成地表下的热岩石压力释放出来。 23 (皇家学会哲学会刊A辑 ,2010年) 在过去10年来,由于全球暖化,高山地区发生土石流和山崩的频率增加了。火山越来越可能崩解,所造成的大型土石流可能会将城市掩埋掉。 24
(牛津大学火山学家大卫_派尔〔David Pyle〕、伦敦大学学院比尔_麦克基尔(Bill McGuire)、英国艾希特大学瑞丘_洛韦〔Rachel Lowe〕) 由于冰川湖泊融化的数量和规模增长,导致溃堤造成洪水的情形不断增加。 25 (加德满都的国际山区整合发展中心〔ICIMOD〕,2010年)
