"Miami South Beach is under water," Sam Champion of The Weather Channel says in the first "weather reports from the future." TV personalities from around the world, also including Jim Cantore from The Weather Channel, appear in the videos.

"Climate change is affecting the weather everywhere. It makes it more extreme and disturbs established patterns. That means more disasters; more uncertainty," the secretary-general said in a statement.

The 2013 U.N. Intergovernmental Panel on Climate Change report concluded that it's at least 95 percent probable that human activity, rather than natural variations in the climate, has been the main cause of global warming since 1950.
