(Multi-) proxy temperature reconstructions over the Common Era are crucial not only to place current temperature trends in a long-term context, but also to assess the full range of natural and anthropogenic climate forcings. However, estimates of the first millennium remain poorly constrained due to a paucity of millennial long tree-ring records causing a spatial under-representation of some regions in larger scale climate reconstructions and increasing uncertainty in the interpretation of climatic trends and extremes.
