SpletMeanwhile, recent satellite images have also shown that unusually large areas of sea ice have been melting during the Arctic summer. Although sea level will not be affected by melting of the floating ice, there will be other important environmental changes. For example, ice sheets act like a mirror, reflecting sunlight and cooling the Earth.

SpletBy Archimedes’s principle, ice shelves floating on the water have already displaced their own weight, so their disintegration or melting won’t change the water level. Ice shelves do, however, regulate the speed of glaciers on Antarctica’s land. As shown in figure 1, ice shelves act to hold glaciers back. Splet11. apr. 2024 · The larger gyre brought warm water closer to the glaciers of West Antarctica, which spill out into the ocean as ice shelves and are vulnerable to melting from below. Within 30 years of its expansion, the gyre could warm the waters beneath the glaciers by 1°C, Valdivia says—an unprecedented heat wave that would accelerate erosion of the ice.
SpletThe issue for sea level rise is ice that is not floating, to simulate that it would be like placing the ice in a funnel above the glass of water. As that ice melts it will flow down the funnel and rise the level of water in the glass. So the problem for sea level rise is the melting of ice that is on land, of which there is a lot.
