When we think of California beaches, we often picture endless stretches of sandy beaches, bright blue skies, and warm sunshine. For many, spending a day at the beach is the ultimate form of relaxation and enjoyment. A recent study warns that climate change is causing sea levels to rise and putting our beaches in danger. The study projects that if sea levels rise by one to two meters, up to 70 percent of Southern California’s beaches could vanish completely by 2100.[1] These disappearing beaches could affect the existing coastal infrastructure or lead to the erosion of sea-cliffs. It is crucial to comprehend the implication of rising sea-levels on our beaches and how it impacts coastal communities, particularly those of color.
According to John Ainsworth, the Executive Director of the California Coastal Commission, preserving our beaches is critical. He notes that there are already equity obstacles eroding access to the beach, “from limited public transportation to illegally blocked pathways.”[2] It is important to acknowledge the impact of rising sea-levels on communities of color who reside near our shorelines. Any efforts to preserve our beaches must consider their needs and concerns. Coastal communities are at risk due to the rise of sea levels. This can result in frequent and severe storm surges, flooding, erosion, and damage to beaches. There are serious consequences associated with these risks, including potential health hazards, deaths, and limitations on recreational activities for impacted areas. It’s crucial to note that communities of color are especially vulnerable to these effects as they often reside in regions with inadequate resources and infrastructure to cope with these changes. This can lead to additional economic struggles and mental stress for these already marginalized communities.
So, what’s causing this rise in sea-levels? Greenhouse gases that trap heat in the atmosphere lead to melting polar ice caps in places like Antarctic and Greenland, which, in turn, leads to the expansion of seawater. NASA estimates that by 2050, sea level along contiguous U.S. coastlines could rise as much as 12 inches (30 centimeters) above today’s waterline, according to researchers who analyzed nearly three decades of satellite observations.[3] Rising sea levels in California are greatly affecting its beaches, resulting in habitat loss for marine life and infrastructure damage. Communities of color, who already live in areas with high air pollution and limited access to nature, face additional challenges due to the impacts of climate change. Environmental racism is evident in Southern California where rising sea levels disproportionately affect these communities. Climate change is not only an environmental issue but also a social justice issue, as the most marginalized communities are at higher risk of flood-related contamination from toxic sites along the California coast.
To tackle the issue of rising sea levels, policymakers should encourage sustainable and nature-focused designs and innovative solutions aimed at reducing damage. One effective way to combat this issue is by supporting initiatives such as the California Sea Level Rise Plan and the California Climate Investments program. These programs involve investing funds in projects specifically designed to help the coast withstand flooding. The initiatives include creating green infrastructure, reinforcing beaches, and building seawalls. However, to ensure that resources are distributed fairly and equitably, more funding is required for implementing these plans.
It is very important to preserve the picturesque environment of California’s beaches, including the refreshing breeze, the melodious chirping of birds, the calming sound of the ocean, and the captivating sunset. These natural wonders are precious resources for both physical and emotional health, and they should be available to posterity. We can all play a part in preserving our beaches and creating a more equitable future. For a deeper dive on similar issues check out our Bio Equity Ed Nature Rx Notes and resources.
