Pacific Climate Futures Version 2.0 is a free web-based climate impacts decision-support tool developed initially by the Pacific Climate Change Science Program (PCCSP) and further refined by the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) Science Program. It provides national and some sub-national climate projections for East Timor and 14 Pacific countries: Cook Islands (two sub-regions), Federated States of Micronesia (two sub-regions), Fiji, Kiribati (three sub-regions), Marshall Islands (two sub-regions), Nauru, Niue, Palau, Papua New Guinea (two sub-regions), Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu.

Built on CSIRO’s Representative Climate Futures Framework (Clarke et al. 2011; Whetton et al. 2012), it includes projections from the global climate modelling experiments (CMIP5) that informed the IPCC’s Fifth Assessment Report as well as those used for the earlier Fourth Assessment Report (CMIP3). The CMIP3 results derive from up to 18 global climate models (GCMs), six of which were dynamically downscaled using a fine-resolution climate model called CCAM. These can be explored for three future time periods (2030, 2055 or 2090) and three emissions scenarios (low-B1, medium-A1B and high-A2). The CMIP5 results are from up to 43 GCMs, six of which were downscaled using CCAM. These projections can be explored for 13 time periods (2030, 2035, 2040...2085, 2090) and four new emissions scenarios (very-low-RCP2.6, low-RCP4.5, medium-RCP6.0 and very-high-RCP8.5).

The Pacific Climate Futures web-tool has been designed to provide information and guidance in the generation of national climate projections and facilitate the generation of data for detailed impact and risk assessments. Pacific Climate Futures lets you to explore the likelihood of future changes in temperature, rainfall, wind, sunshine, humidity and evaporation based on 20-year time periods around 2030, 2055 and 2090 under three greenhouse gas emissions scenarios.

• Relationship to other tools: The Pacific Climate Futures Data Portal receives historic data from the Pacific Climate Change Data Portal, allowing Pacific Climate Futures to produce application-ready future datasets. This tool is able to be used by the public for information on climate projections in the Pacific region.
