limited data availability, access, and capacity to use climate information.
There are at least three specific concerns in relation to the future of the IPCC:
inadequacy of research on regional aspects of climate change, particularly in developing country regions, though an initiative similar to AIACC could help fill gaps;
identifying appropriate roles and actions of IPCC and the U.S. research community; and
demands of climate response research may exceed the capacities of existing global programs (the International Geosphere-Biosphere Programme [IGBP], the International Human Dimensions Programme on Global Environmental Change [IHDP], and the World Climate Research Programme [WCRP], Diversitas).
