Global sea level rise and climate threats

Overview

The United Nations has issued warnings regarding rising sea levels driven by climate change, specifically noting that warming oceans and melting ice sheets are causing significant increases in global mean sea levels. Projections suggest that under high greenhouse gas emission scenarios, sea levels could rise by as much as two meters by 2100. These changes pose a threat to approximately 770 million people living in low-lying areas. Beyond coastal flooding, the rise threatens food and water security through the salinization of agricultural land and freshwater wells, while also risking critical infrastructure and human rights.

Recent data from the European Copernicus program indicates that global average sea levels have risen by approximately 11 centimeters since satellite measurements began in 1993, with the annual rate of rise doubling over the last decade compared to the late 1990s. Six major global cities—Alexandria, Egypt; Jakarta, Indonesia; Shanghai, China; Mumbai, India; Miami, United States; and Bangkok, Thailand—have been identified as being at high risk of submersion. In Alexandria, levels have risen by about 17 centimeters since 1993, while Jakarta has seen an 18-centimeter increase, a danger compounded by land subsidence.

At the 4th Climate Mobility Summit held during the 81st UN General Assembly in New York, leaders addressed these escalating threats. Max Puig of the Dominican Republic’s National Council for Climate Change and Carbon Market emphasized that no Caribbean nation can address these changes in isolation, calling for regional action and international financing. In New York, projections suggest up to 800,000 residents could live in high-risk flood zones by 2050, prompting officials to identify 86 priority zones for infrastructure investments like sewage upgrades and rain gardens.
