In the past decade, climate research has made considerable progress in understanding and modeling climate on timescales of years to decades. At the same time, increasingly more proxies of climatic variables have been detected. Significant progress has been achieved in aligning this evidence in time.
A workshop earlier this year on the state of the art of climate variability studies called for utilizing coupled atmosphere-ocean general circulation models (GCMs) for simulating and analyzing paleoclimatic variability. A fresh attempt is warranted to systematically combine the skills of climate modelers, climate diagnosticians, and paleoclimatologists, agreed participants at the workshop, “Climate Variability on Multidecadal to Millennial Timescales,” sponsored jointly by the Royal Netherlands Meteorological Institute KNMI and the German Federal Research Laboratory GKSS.
