Sea Level Rise Could Look Much Worse by 2100
New research doubles previous predictions if greenhouse gas emissions go unchecked.
Sea level rise can be difficult to imagine concretely. It’s often discussed as a gradual phenomenon, a threat whose effects will only really be felt by far-distant generations.
But new research has made it impossible to continue in this line of thought. In an article published recently in the journal Nature, the scientists Robert DeConto and David Pollard double the prediction for sea level rise expected by the year 2100 from three feet to six feet, if the current rate of greenhouse gas emissions holds steady. By the year 2500, it could hit 50 feet.
