ABSTRACT: Our understanding of natural climate variability rapidly declines over the Common Era (CE) as the pre-instrumental temperature amplitude differs substantially among large-scale reconstructions. Highlighting such differences and emphasizing paleoclimatic findings is crucial for placing anthropogenic climate change in a long-term context. We argue that more proxy records are needed to accurately reconstruct first millennium CE temperature variability and value regional studies producing such data.

古气候的未来

摘要：由于仪表化前温度幅度在大规模重建中存在显着差异，因此我们对自然气候变异的理解在整个共同时期（CE）迅速下降。突出这种差异并强调古气候发现对于将人为气候变化置于长期环境中至关重要。我们认为，需要更多的代理记录来准确地重建第一个千年CE温度变异性并重视产生此类数据的区域研究。
