A melting glacier does not cause the sea level to rise. I can’t believe people don’t understand this. If you have a cup of ice water and melt the ice, the water level stays constant.
One counterpoint, what about when that ice cube is part of a tray of ice that is melting into the cup? My understanding is these glacier sheets are resting on land and sliding into the water.
“ warning that the ice sheets on top of Greenland and Antarctica, which collectively store enough water to cause many more meters of global sea level rise, are already past tipping points”
The article specifically mentions the ice sheets on land.
