Pacific Islands

This final report is for the Pacific Islands-funded project "21st Century High-Resolution Climate Projections for Guam and American Samoa". We provide the projected fine-resolution future climate changes over Guam and American Samoa by the late 21st century (2080-2099) with both a high emissions scenario (RCP8.5) and a medium emission scenario (RCP4.5). We show that the surface air temperature (SAT) over Guam is likely to increase by 1.5 – 2.0 °C for RCP4.5 and by 3.0 – 3.5 °C for RCP8.5, while the projected SAT increases over American Samoa are slightly smaller. The projected annual mean future rainfall changes for Guam are not statistically significant in any location in either the RCP4.5 or RCP8.5 scenarios....
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
