The dated isotope record shows that the fluctuations in global ice volume over the past several hundred thousand years have a pattern: an ice age occurs roughly once every 100,000 years.

同位素年代记录显示，过去几十万年全球冰量的波动有一个模式：冰河期大约每10万年发生一次。

The summer monsoon was driven by global ice volume in the glacial-interglacial scale, and also driven by other factors in more little scale.

夏季风在冰期与间冰期尺度上受全球冰量的影响，但在更短时间尺度上有其它驱动因子。

Earlier this year, scientists warned that sea ice volume reached a record low in 2008 due to an unusually high proportion of the thinner first year ice.

今年的早些时候，科学家们曾发出警告，因为较薄的“一年冰”的比例高于往常，2008年海面冰层的总量会跌至历史新低。

The data from the study also shows that the decrease in ice volume has accelerated in the past five years, as well.

They also look very similar to the simulations coming out of Piomas (Pan-Arctic Ice-Ocean Modelling and Assimilation System), an influential computer model that has been used to estimate Arctic sea-ice volume and which has been the basis for several predictions about when summer sea ice might disappear completely.

The world's most powerful neutrino telescope, IceCube, uses Antarctic ice as the detector volume, with electronic equipment sunk throughout a cubic kilometer of ice -- enough water to fill a million swimming pools -- to detect signals from neutrinos interacting with the ice.
