International, interdisciplinary collaboration between paleoscientists and the climate modelling community is a vital prerequisite to achieving realistic annual to interannual climate predictions. Among the areas of paleoclimate research most relevant to the climate modelling and prediction are:
. Extending the instrumental climate record back in time with annually resolved, quantitative proxy data. Documenting and understanding rapid climate change events. Documenting and understanding natural climate variability during warm interglacial periods, including the Holocene, with background climatic states similar to those of today. Testing the ability of climate models to capture known past climate variability.
The proposed EURESCO series will address each of these key areas within the framework of two conferences: one concentrating on abrupt climate change dynamics and a second on climate variability in the North Atlantic, thought to be a critical region in the forcing of rapid climate change events associated with changes in the global ocean thermohaline circulation. This EURESCO series has been timed so as to complement a series of meetings, which have been planned over the next several years as part of the PAGES/CLIVAR Intersection program. As such it provides an opportunity for a strong European lead within a co-ordinated international effort to improve climate predictability.
