Scientists believe that melting ice is causing the ocean itself to sink in an alarming new study on climate change.
An incredible new report suggests that the ocean itself is sinking under the weight of glaciers that are melting. Previously, scientists had failed to account for how melting glaciers and ice sheets would warp the sea floor or how that would factor into sea level rises.
As a result, satellites may not be measuring the true rise of sea levels worldwide, and therefore don’t accurately reflect the global mean sea level rise. To come to their conclusions, researchers examined the total mass lost from glaciers in Greenland and Antarctica, as well as other factors, and then they calculated how much this increase in water had shoved the seabed downward.
They determined that the seabed and moved down by 0.13 millimeters per year, or 2.5 millimeters between 1993 and 2014. As a result, we may be underestimating sea level rise by as much as 8 percent.
