In the future, there could be major flooding along every coast. So says a new study that warns the world’s seas are rising.
Ever-warming oceans that are melting polar ice could raise sea levels 15 feet in the next 50 to 100 years, NASA’s former climate chief now says. That’s five times higher than previous predictions.
“This is the biggest threat the planet faces,” said James Hansen, the co-author of the new journal article raising that alarm scenario.
“If we get sea level rise of several meters, all coastal cities become dysfunctional,” he said. “The implications of this are just incalculable.”
