大概是一次冰河时代导致了这场大灭绝。南半球表面形成的一个巨大的冰盖引起了全球气候剧变，海平面剧变下降，导致海水中化学成份变得混乱。
An ice age has been blamed for the extinctions - a huge ice sheet in the southern hemisphere caused climate change and a fall in sea level, and messed with the chemistry of the oceans.
汉密尔顿和斯蒂尔恩斯测量的三大冰川约占整个格陵兰冰盖流量的五分之一。

五大湖区是全球最大的淡水“蓄水池”，地球上大约18%的可利用淡水（都在这）——除此之外，只有极地的冰盖才能贮藏更多的淡水。
The Great Lakes comprise the largest collective body of fresh water on the planet, containing roughly 18 percent of Earth's supply. Only the polar ice caps contain more fresh water.
他补充道，格林兰冰盖是否会继续加速融化还是一个大问号。
Whether acceleration of melting from the Greenland Ice Sheet will continue, he added, is a big question mark.
而且我关心三巨头更因为他们对天天破坏我们脆弱的环境，融化我们的两极冰盖负的责任比谁都大。
And I care about what happens with the Big 3 because they are more responsible than almost anyone for the destruction of our fragile atmosphere and the daily melting of our polar ice caps.
基博的冰盖沿冰盖边缘残存下来，形成分散的大冰块。
Gib along the edge of the ice caps ice caps, surviving form the dispersed of ice.
