A group of researchers from Harvard and Rutgers University found the yearly rate of increase from 1900 to 1990 was likely off by a fraction of a millimeter and was actually 1.2 millimeters per year, instead of 1.6 to 1.9 millimeters.
What that means is that instead of an estimated 6.7-inch increase in sea levels over those 90 years, the world actually saw a 4.2-inch increase, a difference of 2.5 inches.
