Our keynote session will feature a national overview of the changes occurring in the upper atmosphere triggering intensity and longevity shifts in weather patterns at the surface. From this presentation, attendees will be able to understand the cascading weather events threatening water safety and security as well as the supporting critical infrastructure and operators in each region across the US. Analyzing recent climate trends over the past 120 years shows strong evidence of growing weather threats to various critical infrastructure sectors as longer lasting heat domes, changes in our winter weather, heavier rainfall events, expansive wildfires, sea level rise, and stronger, more frequent tropical cyclones are occurring nationally against aging infrastructure. As many parts of the water sector were built to climatological standards from the mid to late 1900s, weather events can cause more damage than normal from the increasing intensity and prevalence. Drought conditions have expanded nationally as heat domes and shifts in the rainfall stability have caused surface water levels to drop and reliance on groundwater has reduced what were accessible backup reserves, presenting a concern for water security. In this presentation, attendees will be provided with studies, statistics, and solutions taken from impacted areas and available best practices being advocated across numerous sectors. All of the concepts, statistics, and graphics will be applicable across the U.S. for impacts to consider not just to major waterways, infrastructure, ecological stability, or societal implications, but the subsequent impacts to supply chain and resiliency of multiple sectors, all interlinked, in whole.
