!keynote - Growing Demand for Geographic Information as the Climate Shifts
Geographic information that can better convey the different outcomes for agriculture, forest, or water resource sectors, under different rates of climate change, can improve and inform decisions that potentially reduce the costs and consequences for Arizona and the southwest region. Trees that have survived droughts for over 800 years are crossing lethal thresholds in droughts that are hotter than before. This is one example of how ecosystems are transforming rapidly after repeated severe events or after the most extreme events. The latest developments in understanding of the multiple factors influencing wildfire risks require enhanced and near-real time geographic information to provide reliable decision support. Elevations are shifting as water resources respond to extremes in precipitation variability. Reductions in Colorado River flow occurs with each higher degree temperature increase under what scientists call a hot drought. The associated economic consequences would be substantial for the region. However, economic risks can be decreased across multiple sectors with reduced carbon emissions and adaptation.
In this presentation, Dr. Ekwurzel will share information on how Arizona geospatial professionals can benefit from resources already available in the National Climate Assessment Vol I (The Climate Science Special Report) that addresses global change. Learn about how to access customized county-level maps of over 40 climate variables through Climate Explorer. Practical tools can help plan for the future such as Localized Constructed Analogs (LOCA) downscaled projections to see how future global climate scenarios are expected to influence
