Ice shelves form in areas where cold ocean water lies next to a large continental glacier or ice sheet that reaches the sea. Under cooling or cold conditions, the ice that reaches the sea will …

Because ice shelves are exposed to both the air above and the ocean below, ice shelves respond more quickly than ice sheets or glaciers to rising temperatures. Ice shelves do not contribute …
