SOUTHERN CALIFORNIA EDISON Co

Climate change has, and continues to, impact California. Southern California has warmed 3 degrees Fahrenheit in the last century, snowpack has declined, and, according to a 2022 study, the drought from 2020 to 2021 in the Western United States and Northern Mexico was their driest period in at least 1,200 years. Severe droughts and windstorms contributed to the devastating wildfires that swept through parts of California in recent years, demonstrating the serious threat that weather extremes caused by climate change pose to California's communities and the environment. See "Management Overview—Southern California Wildfires and Mudslides" in the MD&A and "Business—Southern California Wildfires."

Severe weather events, including drought, increasingly severe windstorms and rising sea-levels, pose risks to SCE's infrastructure and SCE and Edison International are investing in building a more resilient grid to reduce climate- and weather-related vulnerabilities. See " Liquidity and Capital Resources—SCE—Regulatory Proceedings—Wildfire Related Regulatory Proceedings" in the MD&A.

In May 2022, SCE provided its climate adaptability vulnerability assessment (“CAVA”) to the CPUC. The CAVA addresses the projected climate impacts of temperature, sea level, precipitation, wildfire, and cascading impacts (such as rain on snow or debris flow) on SCE in the 2030, 2050, and 2070 timeframes. SCE's CAVA will inform planning related

to SCE assets, operations, and services, with the goal of maintaining a resilient electric grid in the face of climate change and will inform future investment in the grid.
