There is much to be done on the area of exploring how models simulate the climate variability (and the nature of the association with forcings) that we reconstruct from the palaeodata. Many people, scientists among them, believe that the issue of global warming has nothing to gain from palaeolcimate studies and they are wrong. Issues such as the climate sensitivity of models versus the real world and the roles of specific forcings and their influence on the future, represent important foci for continued study. I would like to see this area of work and collaboration between palaeoclimatologists and climate (and ecological) modelers as an explicit priority of future work.
