California enfrentará inundaciones crónicas

The Union of Concerned Scientists identifies several California communities, including Alameda and San Mateo, that face 'chronic flooding'—defined as high tides flooding 10% or more of usable land at least 26 times per year—by the end of the century. Under a high-emission scenario, these impacts could arrive by 2080. Critical national security infrastructure, such as the Naval Station San Diego, is also at risk. The document argues that limiting global warming to 1.8°C could prevent any California community from reaching the chronic flooding threshold by 2100 and urges immediate policy reforms regarding coastal development, disaster funding, and population relocation.

• Chronic flooding is defined as occurring when high tides inundate 10% or more of a community's usable, non-wetland area at least 26 times per year, or roughly once every two weeks.
• Under an intermediate sea-level rise scenario, Alameda, San Mateo, and Costa Norte (including Huntington Beach) will face chronic flooding by 2100; under a high scenario, this timeline accelerates to 2080. In Alameda, 35% of the area, including industrial zones and densely populated neighborhoods, would be affected.
• Significant US national security infrastructure in San Diego is vulnerable: the Naval Station San Diego piers could face frequent flooding by 2060, and by 2100, over one-third of the Naval Station San Diego, the Marine Corps Recruit Depot San Diego, and most of the Naval Amphibious Base Coronado would be regularly flooded.
• Limiting global warming to approximately 1.8°C could prevent any community in California from experiencing chronic flooding (10% area inundation) before the end of the century.
• The document recommends three policy categories: ending policies that encourage risky coastal development, improving existing disaster frameworks (such as FEMA programs), and creating new measures for population relocation and the preservation of natural ecosystems.
