The Reality of Climate Change in the San Gabriel Foothills

January 2025

As a resident living near Altadena, the questions raised by the Eaton Fire extend far beyond immediate recovery. The San Gabriel foothills face an increasingly unstable future, where traditional patterns of development and community life may become untenable. The Santa Ana winds that drove the January fires reached unprecedented speeds, transforming familiar canyon paths into blowtorch corridors. These same steep topographical features that make our communities distinctive now amplify our vulnerability.

The cascade of environmental threats presents a particularly complex challenge. When winter rains arrive, the denuded hillsides will create new risks of mudslides and debris flows. Our infrastructure - power lines, water systems, roads - was designed for a more predictable climate regime. As weather extremes intensify, these systems face increasing strain. The question isn't simply how to rebuild what was lost, but whether our current patterns of foothill habitation can endure.

Insurance companies are already signaling their doubts. As they withdraw from the market or multiply their premiums, they force us to confront difficult questions about the future of these communities. The traditional California dream of homes nestled in the chaparral may be colliding with new climate realities. Yet these aren't just matters of actuarial calculations - they're questions about community, culture, and identity.
