Historical and reanalysis data sets are used to find related atmospheric circulation and sea surface temperature patterns. One objective of such studies is to understand the teleconnections that control the low frequency variations in the proxy records. In the ideal case, the method provides for a reconstruction of climate modes beyond the instrumental record. It can also bring climate shifts, such as that observed in the 1970s, into a long-term context. The proxy data can provide estimates of natural climate variability in the pre-industrial era. This seems to be very important in terms of detection of the anthropogenic influence on climate change.

Examples:

• Arctic Oscillation signature in a Red Sea coral.
• Increased seasonality in Middle East temperatures during the last interglacial period.
• Climate teleconnections recorded in Danube river flow. Rimbu, N., Dima, M., Lohmann, G., and Stefan, S., 2004. Geophysical research letters, 31, No. 23, L23203, doi:10.1029/2004GL020559.
