Unlike past projections, this set of potential scenarios affecting greenhouse gas emissions adds a “moderate” prediction. But even a more moderate analysis projects sea levels rising between 2 feet and 5.1 feet by the end of this century. And if the goals of the Paris climate accord are met, sea levels are still projected to rise from 1.7 feet to 3.9 feet over that time span.
“Up to 2050, sea level rise is going to be what it is,’’ agreed Jeanne Herb, executive director of the Environmental Analysis and Communications Group at Rutgers University’s School of Bloustein School of Planning and Public Policy.
