Abstract :
It is essential to characterize well past natural climate variations to detect the potential anthropogenic contribution in recent changes. Past variations also allow studying the dynamics of the climate system for a range of conditions broader than the one observed recently. The past millennium appears particularly interesting in this framework as the conditions are similar to those observed currently, except that the human impact was much lower. The reconstruction of past climate changes is based on indirect observations as the instrumental data cover less than 150 years in most regions. Different techniques exists. The goal here is to illustrate how climate models results and indirect records derived from natural archives can be combined to obtain estimates of past states of the climate system and of the mechanisms responsible for the past climate changes.
