A 1-meter rise in sea levels by 2100 poses catastrophic risks, displacing tens of millions of people, drowning coastal infrastructure, and causing severe economic damage. It is projected to cause chronic flooding, destroy critical ecosystems, and induce "catastrophic inland migration".
Key Impacts of a 1m Sea Level Rise:
Population Displacement and Safety: Millions living on low-lying islands, coastal villages, and delta regions will be displaced. Over 100,000 properties in England alone are at risk by the 2080s.
Infrastructure Damage: Coastal cities, ports, and critical infrastructure (including potential damage to internet cables) will face increased flooding and erosion, incurring huge repair costs.
Economic Consequences: Global annual flood costs could reach US$ 14 trillion, with some countries seeing flood damage costs representing a significant portion of their GDP.
Environmental Degradation: Coastal wetlands, coastal habitats, and coral reefs will likely be destroyed or severely damaged.
Water and Agriculture: Saltwater intrusion will contaminate freshwater aquifers and destroy agricultural crops in coastal fields.
Increased Storm Surge Power: Higher baseline sea levels allow storms, hurricanes, and typhoons to push water much further inland.
