More studies are out that show that sea levels across the world are rising due because of man-made global warming.
Currently, sea levels are rising several times faster than they have in the past 2800 years.
Before industrialization the fastest sea levels rose was about one to one and a half inches per century, but in the 1900s, sea levels rose five and a half inches.
If greenhouse gases continue to be emitted at the current rate, sea levels are projected to rise anywhere from 11 to 52 inches by 2100.
