Cal-Adapt serves a critical need as a reliable source of climate data for the fossil fuel sector. This work increased the trustworthiness and utility of the Cal-Adapt enterprise through developing scientific and statistical best practices with cutting-edge tools and visualizations. Visualizations developed by Cal-Adapt provide insight into how climate change will impact fossil fuel operations and highlights the urgent need to rapidly decarbonize the global energy system to both improve the environment and advance California’s ambitious environmental mandates. This work also identifies key gaps in climate data and climate services and outlines solutions by presenting a pathway for future California climate assessments that avoid climate related pitfalls and delays. A forward-looking, expanding Cal-Adapt enterprise creates oppor-tunities for increasing ratepayer benefits at a lower cost through cloud computing and narrowing the gap between climate and energy system modeling through informed tool development. This work supports Cal-Adapt's move away from educating users and instead leads Cal-Adapt toward a comprehensive climate data service for a more resilient fossil fuel system.
