During Wednesday’s Democratic presidential debate, 2020 Democratic presidential candidate Senator Bernie Sanders (I-VT) stated that scientists are saying that “if we don’t get our act together within the next eight or nine years,” major cities will go underwater because of climate change.

Sanders said, “We don’t have decades. What the scientists are telling us, if we don’t get our act together within the next eight or nine years, we’re talking about cities all over the world, major cities going underwater. We’re talking about increased drought. We’re talking about increased extreme weather disturbances. The United Nations is telling us that in the years to come, there are going to be hundreds of millions of climate refugees causing national security issues all over the world.”
