Notes

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 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.
