Our project focuses on understanding patterns and causes of recent population declines in the Haleakala silversword that are associated with decreasing precipitation, increasing temperature, and related climate changes in Hawaii’s high-elevation ecosystems. The Haleakala silversword is an ideal taxon with which to assess impacts from climate change. It forms the foundation of a diverse alpine community and likely reflects wider ecological changes; it is already exhibiting patterns of mortality consistent with an upslope shifting distribution; and its high visibility and symbolic status make it unmatched in educational potential. Building on extensive research infrastructure, we propose to collect the demographic...

Coral reef ecosystems are exposed to a diverse suite of environmental forcing. Waves, wind, currents, temperature, irradiance, salinity, nutrients, turbidity, aragonite saturation state, and planktonic productivity each influence coral reefs to varying degrees, fluctuating on daily, seasonal and interannual time scales and across spatial scales spanning reefs, islands and archipelagos [1-3]. Environmental forcing is highly influential to reef ecosystem process and function, including coral reef extent and growth rates and the abundance, diversity, and morphology of reef organisms [1, 4]. Through time, coral reef ecosystems have adapted to exist within a particular climatological setting; a finite range in long-term...

Changes in future wave climates in the tropical Pacific Ocean from global climate change are not well understood. Spatially and temporally varying waves dominate coastal morphology and ecosystem structure of the islands throughout the tropical Pacific. Waves also impact coastal infrastructure, natural and cultural resources, and coastal-related economic activities of the islands. Wave heights, periods, and directions were forecast through the year 2100 using wind parameter outputs from four atmosphere-ocean global climate models from the Coupled Model Inter-Comparison Project, Phase 5, for Representative Concentration Pathways (RCP) scenarios 4.5 and 8.5 that correspond to moderately mitigated and unmitigated greenhouse...

Traditional Ecological Knowledge, or TEK, is “a cumulative body of knowledge, practice and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationships of living beings (including humans) with one another and with their environments.” With support from the PICCC, scientists at the University of Hawai’i Mà„noa have undertaken research that is documenting baseline Traditional Ecological Knowledge for Ka’upulehu, in the north Kona region of Kekaha on Hawai‘i Island. This focused on biological and cultural resources most valued by the community, the challenges they face, and potential coping mechanisms. Through a series of workshops, investigators partnered...

This report is published as one of a series of technical inputs to the National Climate Assessment (NCA) 2013 report. The NCA is being conducted under the auspices of the Global Change Research Act of 1990, which requires a report to the President and Congress every four years on the status of climate change science and impacts. The NCA informs the nation about already observed changes, the current status of the climate, and anticipated trends for the future. The NCA report process integrates scientific information from multiple sources and sectors to highlight key findings and significant gaps in our knowledge. Findings from the NCA provide input to federal science priorities and are used by U.S. citizens, communities,...

Coral reefs are seriously threatened by ocean acidification and climate change impacts like coral bleaching. Importantly though, the degree of threat varies for different coral reef areas due to differences in local and regional climate drivers. Climate models are based on the scientific community’s understanding of climate drivers and were used during this project to look forward or ‘project’ conditions in coral reef areas. The projections are global maps that depict changes in acidification and the frequency and severity of the temperature stress events that cause coral bleaching. The project team found that the date by which really severe bleaching is projected to occur annually varies with latitude. Beyond this...
