Met Office reports sea level rise impacts infrastructure in Portishead
What happened
The Met Office reported that sea levels around the UK have risen by approximately 20.1 centimetres since 1901, with about two-thirds of that rise occurring in the last 30 years, indicating an acceleration in the trend. This rise, combined with unpredictable rainfall patterns, is affecting the infrastructure of Portishead. The Met Office also noted that the salt marsh acts as a buffer, reducing flood risks by absorbing wave energy.
Why it matters
The increasing sea level rise and unpredictable weather heighten the need for maintaining coastal defenses and preparing for future changes in Portishead. Past events, such as the breaching of the sea wall in 1981 and 1990, highlight the vulnerability of the area. This trend places planning challenges on North Somerset and increases the operational burden for flood risk management bodies.
Sea level rise is impacting European infrastructure, specifically ports and airports.
