1·More recent geologic studies documented deglaciation and the existence of ice-free areas throughout major coastal areas of British Columbia, Canada, by 13,000 years ago.

更多近期的地质研究证明了13000年前的冰川消退现象和整个加拿大不列颠哥伦比亚省主要沿海地区内无冰区的存在。

2·Although change in carbon dioxide content closely follows change in temperature during periods of deglaciation, it apparently lags behind temperature during periods of cooling.

虽然在冰川消退期间二氧化碳含量的变化与温度的变化密切相关，但它显然滞后于冷却期间的温度。

3·Can deglaciation trigger earthquakes in N. America?

冰川消退能触发北美洲的地震吗？

4·Little is known about climatic conditions in the tropics during the last glacial period and the deglaciation that followed.

人们对最后一次冰期热带的气候条件以及随后发生的冰川消退知之甚少。
