caption This is the Mertz Glacier in January 2017. source Alessandro Silvano Warm waters are pooling underneath Antarctic glaciers in a way that’s causing glaciers to melt more rapidly and preventing the formation of cool water beneath Antarctica, according to a new study. This could slow ocean currents and potentially lead to a rapid sea-level rise event known as a pulse. Such an event could be devastating, causing sea levels to rise by more than 10 feet by the end of the century. The worst-case climate scenario for coastal cities is known as a “pulse.” In that situation, abnormally warm water could cause the glaciers that hold back ice sheets on top of Antarctica and Greenland to collapse. That would cause massive quantities of ice to pour into the world’s oceans, which could lead to extremely rapid sea-level rise around the world. If such a scenario were to occur, current sea-level rise predictions for vulnerable cities like Miami would be far too low. Right now, scientists predict Miami will likely be surrounded by seas up to 7 or 8 feet higher than they were in 1900 by the end of this century. But in the case of a pulse, some… Read full this story
