It is known that the Little Ice Age cooling began in Greenland and the Arctic in about 1200.

据了解，小冰河期的降温始于约1200年的格陵兰岛和北极。

Without those masses of cooling sea ice, warm air brought to the Arctic can penetrate further inland than it ever did before.

如果没有这些大量冷却的海冰，被带到北极的暖空气可以比以前更深入渗透到内陆。

Two new studies of past warming and cooling periods going back millions of years have found that the Arctic reliably amplifies whatever global climate is doing.

对过去几百万年来气候变暖和变冷阶段的两项新研究发现，无论全球气候怎样变化，北极必定放大其变化幅度。

For a very large part of the energy requirement of such centres (other than one Facebook one which was deliberately placed in near Arctic conditions) is that necessary cooling, rather than the electricity demands of the computing itself.
