Abstract

An increasing number of terrestrial and marine proxy records for temperature, hydrology, and oceanic circulation over the past millennium are becoming available, providing a reference frame for the assessment of current and future climate change. The spatial and temporal resolution of these proxies, however, is still limited, hindering the analysis of dynamical processes of regional to global climate changes. These processes can be simulated and interpreted using coupled climate models, which can also aid in separating externally forced climate signals (e.g., solar variability and anthropogenic forcing) from internal climate variability. Understanding of natural climate variability and underlying dynamics can be further improved by relating past variations to statistical models of climate processes.
