If the studied cities, most of which are located in Asia, do not defend against the "unprecedented levels" of sea exposure, the researchers found, they could face "partial to near-total extant area losses." Roughly 50 major coastal cities will need to implement unprecedented adaptation measures to prevent rising seas from swallowing their most populated areas, a new study shows. The extreme emissions scenario of 4 degrees Celsius is projected to cause sea levels to rise a median of 8.9 meters (more than 21 feet) within 200 to 2,000 years. Researchers looked at 50 major cities worldwide to project how a range of global warming scenarios - from 1.1 to 4 degrees Celsius of warming - would impact their local sea levels in the coming centuries. Some of Australia’s most densely populated suburbs, major cities and crucial pieces of infrastructure, such as Sydney airport, could be underwater in just decades, according to an alarming new. If high carbon dioxide emissions continue, researchers with the nonprofit organization Climate Central found, land that is home to at least 10% of the global population could end up at least partially underwater. New images and research paint a grim picture of what the future may look like if the world fails to adequately address climate change.
