To build up a better picture of fluctuations appreciably further back in time requires us to use proxyrecords.
为了更好地了解更早时期的波动,我们需要使用代理记录。

Studies suggest that to date the variability in computer simulations is considerably smaller than in data obtained from the proxyrecords.
研究表明,迄今为止,计算机模拟的可变性比从代理记录中获得的数据要小得多。

For the time before records began, we have only "proxyrecords" reconstructed largely from tree rings and ice cores, supplemented by a few incomplete written accounts.
