The world’s climate is changing, or as Andy Bochman, Senior Grid Strategist, National & Homeland Security, for Idaho National Lab, likes to say we’re experiencing global weirding. Extreme weather events are occurring more frequently and with higher intensity, impacting the grid and exposing its vulnerabilities. How can utilities better prepare infrastructure for the changing climate and extreme weather events? This two part series on climate risk features Andy, and his colleague Tom Wall, Program Lead, Engineering & Applied Resilience, at Argonne National Laboratory who work with climate models to understand infrastructure resilience. In part one, Andy and Tom explain global climate models and how they downscale data to the local level to make it actionable.
