Cómo el aumento del nivel del mar y las inundaciones de las mareas amenazan a las comunidades en las costas en los próximos 30 años

The report warns that tidal flooding will become chronic and disruptive for many US coastal communities by 2030 and 2045, necessitating urgent local adaptation and national carbon emission reductions.

• Global sea levels rose approximately eight inches between 1880 and 2009 due to thermal expansion of seawater and the accelerated melting of land ice caused by global warming.
• By 2030, more than half of the 52 analyzed communities on the East and Gulf coasts are expected to experience an average of over 24 tidal floods per year, with two-thirds potentially seeing a tripling or more of their current annual flood frequency.
• Specific high-risk areas include Annapolis, MD, and Washington, DC, which could average over 150 tidal floods annually by 2030, while parts of New Jersey may see 80 or more.
• By 2045, one-third of the analyzed sites are projected to face more than 180 floods per year, with nine locations, including Atlantic City and Cape May, NJ, potentially experiencing 240 or more annual events.
• Communities currently experiencing minimal flooding will see a significant increase by 2045; for example, New London, CT, may go from two annual floods to over 35, and some sites could see a tenfold increase.
• The Gulf Coast is expected to see many new areas exposed to tidal flooding by 2045, specifically mentioning Freeport, Rockport, and Sabine Pass, TX, which could face 35 to 70 floods per year.
• The document argues that while short-term sea level rise is largely guaranteed, long-term impacts can be mitigated if global carbon emissions peak and begin to decline by the end of the 2010s to keep warming below 2°C.
