How reliable are reconstructions and models for past temperature changes?

An understanding of climate changes during the past millennia is crucial for the scientific attribution of the current warming and the accurate prediction of future climate change. The proxy-based reconstructions and model simulations that offer insights into past temperature changes, however, are subject to large uncertainties. Large-scale climate reconstructions are always related to the uncertainties arising from the disturbance of non-climate signals in individual proxy record, and the differences in seasonality or temporal resolution for different proxy records.
