UN warns rising sea levels are accelerating, threatening 770 million people and potentially displacing 1.2 billion by 2050

The United Nations reports that the ocean is rising faster now than at any point in recorded history, with its impacts already being felt globally. Approximately 770 million people, or one in ten humans, live less than five meters above the high tide line, facing challenges such as saltwater intrusion into freshwater wells and farmland, damage to hospitals, schools, and sanitation systems, and increased exposure to waterborne diseases. Some projections suggest that up to 1.2 billion people could be displaced globally by 2050 due to rising sea levels, highlighting a growing humanitarian and economic crisis.
