本文件已被Temperature reconstruction last two millennia.svg取代。建议您使用其他文件。请注意，删除被取代的图片需要达成一致。 使用其他文件的理由：“The old reconstructions were based on limited data, which was biased towards the Northern Hemisphere. The new file is also svg, and translatable”

1. Data from Moberg et al. was taken directly from the supplemental information accompanying the Nature article.
2. Data for Oerlemans was provided by William M. Connolley.
3. Esper et al. reported only fluctuations in "arbitrary" units, so the variance in this record was rescaled to match the variance during the period of overlap with the instrumental record.
4. When a paper included multiple reconstructions, the global annually average temperature data was used. If this was not reported, then Northern Hemisphere annually averaged data was used.
5. Four records appearing at [4] were not used in preparing this graph for the following reasons:
   1. Mann et al. 98 was not included because Mann et al. 99 extended and updated that record.
   2. Briffa et al. 98 was not included because Briffa et al. 2001 extended and updated that record.
   3. Pollack et al. 98 was not included because the reported data was not found to be in a form that allowed for easy replotting.
   4. Mann et al. 2000 was not used because it did not include an original reconstruction covering at least the Northern Hemisphere.

此graph图片可使用矢量图形重新创建为SVG文件。这具有很多好处；更多信息请参见共享资源:待清理媒体。如果存在此图片的SVG格式，请将其上传，然后将此模板替换为{{vector version available|新图片名称}}。 建议您将SVG命名为“2000 Year Temperature Comparison.svg”，这样在使用Vector version available（或Vva）模板时就不需要填写新图片名称参数。
