Led by university consortium institutions of the South Central Climate Adaptation Science Center (South Central CASC), this project builds on the successes of similar workshops in 2014, 2016, and 2018 to bring together a cohort of graduate students, post-docs, and early-career environmental professionals within the South Central CASC region and mentor this cohort to become the next generation of USGS leaders and partners. The objectives of the workshop were to: (1) develop the early-career participants’ knowledge, leadership skills, and interdisciplinary collaboration; (2) introduce participants to the goals, structure, and unique research-related challenges of the South Central CASC, its place within the U.S. Department...

Future climate projections illuminate our understanding of the climate system and generate data products often used in climate impact assessments. Statistical downscaling (SD) is commonly used to address biases in global climate models (GCM) and to translate large‐scale projected changes to the higher spatial resolutions desired for regional and local scale studies. However, downscaled climate projections are sensitive to method configuration and input data source choices made during the downscaling process that can affect a projection's ultimate suitability for particular impact assessments. Quantifying how changes in inputs or parameters affect SD‐generated projections of precipitation is critical for improving...

The greater Mississippi River Basin (MRB) drains 3.2 million square kilometers of land and spans 31 U.S. states. Ninety percent of all U.S. agricultural exports are grown in the MRB, and about 40 percent of the nation's total exports are transported through its major rivers. Ecologically, 24 terrestrial ecoregions comprise MRB, supporting amphibious, reptile, and mammal species. MRB provides habitat for almost 250 fish and 50 mussel species, its floodplain supports about 40 percent of North America’s wading birds and waterfowl, and over 180 National Wildlife Refuges operate across this region. Climate change is projected to disrupt the amount, frequency, extent, and timing of precipitation events across the MRB....

Abstract Although decision-making in response to tornado warnings is well researched, most studies do not examine whether individual responses to these warnings vary across different geographical locations and demographic groups. This gap is addressed by using data from a decision experiment that places participants virtually in a simulated tornado warning and asks them to minimize the costs of their decisions. The authors examine the following: 1) what demographic attributes may contribute to choices to minimize costs to protect assets at a specific location in a tornado warning, 2) whether there is a spatial component to how these attributes influence decision-making, and 3) if there are specific U.S. regions...

The Ogallala Aquifer (OA) is a groundwater source beneath 111 million acres of Wyoming, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico. It provides water for aquatic, riparian, range, and agricultural ecosystems as well as approximately 1.9 million people. The various social, economic, and ecological challenges of managing the aquifer are expected to increase with climate change. Hotter, drier summers are expected to increase already unsustainable demands on the aquifer’s water. There has been little success in reducing the rate of depletion, in spite of a preponderance of data available to support research, resource management, and outreach. Prior to this project, there was no single...

Led by members of the South Central Climate Science Center (SC CSC) consortium, this project developed and implemented a professional development workshop for graduate students, post-docs, and early-career researchers within the SC CSC region. The workshop (1) introduced participants to the goals, structure, and unique research-related challenges of the SC CSC and its place within the U.S. Department of the Interior and the larger CSC network, offering them insight into how their research fits into the broader research priority goals and its eventual applicability to end-user needs across the region; (2) provided an opportunity for participants to present their research to fellow peers; (3) facilitated interdisciplinary...
Abstract (from AGUPubs): To assist water managers in south-central Oklahoma prepare for future drought, reliable place-based drought forecasts are produced. Past-, present-, and future-forecasted climate indices (Multivariate ENSO Index, Pacific Decadal Oscillation index, and Atlantic Multidecadal Oscillation index) and past and present Palmer Drought Severity Index (PDSI) are employed as predictor variables to forecast PDSI using a multivariate regression technique. PDSI is forecasted 18 months in advance with sufficient skill to provide water managers early warning of drought. Using a training data set obtained from the period January 1901 to November 2021, a second-order model equation that contains, without...
