Multi-isotope analysis of palaeofauna sequences as indicators of past environments and climates

在过去的10万年里，地形发生了巨大的变化，这主要是由于地球气候的变化。我们可以从保存下来的古生物和考古遗址中发现的遗骸中看到生活在这些景观中的动植物的物种和类型在这段时间内发生变化的证据。我们也有证据表明，从北极和南极回收的冰芯中的同位素特征测量结果表明，全球气候发生了多大变化。然而，当我们观察特定地区和地区的景观时，我们几乎没有方法来确定当地的气候和环境是如何变化的。冰芯记录记录了全球气候，但局部可能存在微气候，其气候和环境变化可能与冰芯记录的不同。如果附近有适合进行这项分析的水体，也有可能从湖泊沉积物中获得气候记录。

Landscapes have changed dramatically over the past 100,000 years, largely due to changes in the Earth’s climate. We can see evidence for the changes in the species and types of plants and animals that live in these landscapes over this time from their remains that have been preserved and then recovered from palaeontological and archaeological sites. We also have evidence for how much the climate has changed globally from the measurements of isotope signatures in ice cores recovered from the north and south poles. However, we have few methods of determining how the climate and environment changed locally when we are looking at landscapes in specific areas and regions. The ice core record records global climates, but locally there can be micro-climates that may have different climate and environmental changes than is recorded in the ice cores. It is also possible to get a record of the climate from lake sediments, if there is a nearby body of water suitable for this analysis.
