He was the European co-ordinator for the IGCP-253 Termination of the Pleistocene ‘North Atlantic Seaboard Program’ (1990-1994), and co-founder, in 1995 of INTIMATE (Integration of Ice core, Marine and Terrestrial Records), now a core program of the INQUA (International Union for Quaternary Research) Palaeoclimate Commission. However, human beings love to see factual precision, and we want to know how old something is.Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range.
