Abstract:
A steep decline in the quality and quantity of available climate proxy records before medieval times challenges
any comparison of reconstructed temperature and hydroclimate trends and extremes between the first and
second half of the Common Era. Understanding of the physical causes, ecological responses and societal con-
sequences of past climatic changes, however, demands highly-resolved, spatially-explicit, seasonally-defined and
absolutely-dated archives over the entire period in question. Continuous efforts to improve existing proxy records
and reconstruction methods and to develop new ones, as well as clear communication of all uncertainties (within
and beyond academia) must be central tasks for the paleoclimate community.
