The Fourth Assessment Report of the IPCC (IPCC AR4) Working Group II (2007) identifies small island states as being among the most vulnerable countries of the world to the adverse impacts of climate change. Hay, el al.y (2003) in discussing the Pacific's observed climate noted that compared to earlier historical records during the twentieth century, the southern Pacific had experienced a significantly drier and warmer climate (by 15 percent and 0.8°C, respectively).
The need for a Pacific Biodiversity Information Forum to provide a venue and support for biodiversity information needs in the Pacific Basin was established during the GBIF (Global Biodiversity Information Facility) meeting on Maui in May of 2002. Interested parties met again during the October 2003 GBIF meeting in Tsukuba, Japan and reaffirmed the need and began to draw up a governing structure for PBIF and identify specific biodiversity needs in the Pacific Basin that can be addressed through projects.
