To synthesize the vast array of observational data, twelve regions were defined by the CAPE steering committee. Each of these regions were then divided into the terrestrial and marine realms for ease of data synthesis.

At the Lammi meeting, several maps were created which compare the observed paleodata with GCM simulations. Several maps, one for each 1000-year timeslice of the Holocene were generated which plot the temperature and biome comparisons with the present. These maps were the major contribution of the CAPE meeting in Lammi.

Maps of the marine reconstructions, based upon planktonic foraminiferal assemblages, benthic temperatures, and benthic assemblages, have just been added. Please take some time to peruse THE MAPS.
