Ice shelves in Antarctica surround about three-quarters of the continent. While ice shelf loss doesn't directly cause sea level rise, it can impact land ice loss by buttressing it and slowing its descent into the ocean.
"Antarctica has been losing sea ice, grounded ice, and floating ice shelf mass over the past few decades. Satellite analysis from NASA groups show trends of ice loss, and the same trends have been reported by independent research groups from around the world." - Chad Greene, Glaciologist at NASA's Jet Propulsion Laboratory
"The truth is, it is unclear if Antarctica is losing any ice on balance or if it's currently experiencing a net gain," the video's narrator inaccurately said, citing two scientific papers.
