To better understand impacts of climate change across diverse sectors in Hawaii, resource managers and scientists collaborate with climate modelers who create projections of future climate conditions, such as changes in patterns of rainfall and temperature at the end of the 21st century. To make global climate projections applicable for Hawaii, the models must be downscaled (see Figure 1) to provide increased spatial detail for resource managers and cultural stewards. Different methods and models are used, and because these are projections for many decades from now, the results often span a range of possibilities. A Workshop held in September 2015 brought climate modelers and resource managers together to discuss areas of agreement about different aspects of climate projection. The purpose of this document is to summarize levels of expert consensus across different climate projections, and to offer guidance for resource managers, cultural stewards, and community leaders to better understand applications and limitations of available projections for the State.
