The preparations for IPY 2007/2008 are evolving from conceptual to implementation planning. Many earth scientists are concerned that the emerging plans for IPY are too narrowly focused on environmental processes and therefore appear discriminatory with respect to other fundamental sciences. National/international efforts such as USGCRP (U.S. Global Change Research program) and IPCC (Intergovernmental Panel on Climate Change) are also involved in the multitude of climate change issues, and just how the proposed IPY program could augment and complement these ongoing activities without reproducing them requires careful analysis and coordination. In particular, the polar research is unthinkable without study of the geological history of the Arctic and the Southern Oceans as a clue to tectonic evolution of the entire planet and test of the current geodynamic paradigm. In addition to these fundamental objectives, the circum-polar continental margins of the Arctic and Antarctica are likely to become the scenes of geopolitical intrigue provoked by implementation of the provisions of the Law of the Sea that require acquisition of specific earth science knowledge at internationally recognized levels of credibility.
Interdisciplinary international programs (e. g. JEODI), based on geophysical data acquisition and analysis that would lead, where appropriate, to scientific drilling, had independently been proposed for studying the coupled tectonic and oceanographic history of the polar regions. Admitting the importance of identifying fundamental constraints for paleooceanography and climatic history of the high latitudes, and acknowledging the progress achieved so far in promoting IPY activities, the international earth science community has suggested developing the proposed approach into a major IPY endeavor - to examine the Polar Ocean Gateway Evolution (POGE). Such study would enable linking the geological history of the Polar Regions during the last 100 Ma and related fundamental changes that occurred in the face of the Earth with modern consequences of these processes and their impact on contemporary world. In good agreement with this project idea, although on a shorter time scale, is another initiative SALE (Subglacial Antarctic Lake Exploration) that has also been submitted for consideration in IPY context. It is hoped that IASC, SCAR and IUGS will take an active stand in endorsing earth science component of IPY, and that other bodies responsible for formulating IPY agenda will eventually recognize the fundamental importance of learning the past in order to understand the present and predict the future.
