California’s scenic highways, including California Highway 1, Volcanic Legacy Scenic Byway, and Pacific Coast Highway, are facing challenges due to the climate crisis. Record-breaking winter storms, drought, wildfires, and coastal erosion have impacted these iconic routes. While scientists are still debating the role of human-caused climate change in intensifying these events, they predict that such occurrences will worsen as the world continues to warm.
The Volcanic Legacy Scenic Byway, known for its ancient lava fields and scenic lakes, has been affected by fire and flood. Recent storms have caused road washouts, mudslides, and damage to landscapes already scarred by wildfires. The effects of prolonged drought are also evident along the California-Oregon border, where wetlands have been drained or diverted for agriculture. Efforts are underway, including the country’s largest dam-removal project, to restore the Klamath River and promote system-wide recovery.
Highway 395, which stretches across more than 1,300 miles, has experienced the impact of severe winter storms and extreme heat. The Sonora Pass, a scenic route in the Sierra Nevada range, was closed for 211 days due to heavy snowfall. The drive along Highway 395 showcases dramatic shifts in landscape, from mountainous regions to high-desert terrain. Owens Lake, once drained to supply water to Los Angeles, is now showing signs of returning to life after receiving runoff from the Sierra snow.
The Pacific Coast Highway, renowned for its stunning views where the mountains meet the Pacific, has been plagued by landslides and coastal erosion. The road has faced ongoing closures, impacting tourism and local businesses. Sections of the highway have been closed for months at a time, with repairs becoming a challenging and continuous endeavor. Despite these challenges, there remains optimism among local communities about finding solutions to preserve and restore these natural wonders.
As California’s scenic highways continue to grapple with the effects of the climate crisis, the need for adaptation and resilience becomes increasingly apparent. These iconic routes serve as a frontline view of the changing landscapes and offer a glimpse into the future challenges posed by climate change.
