Oxford [UK], October 17 (ANI): Sea levels are rising as a result of climate change due to ocean expansion and ice melting on land. Sea level rise in the near future will be influenced by a number of factors, some of which include how frequently glaciers calve. These happen when big chunks of ice break off from tidewater glaciers, or glaciers that finish in the ocean, and fall into coastal fjords as icebergs. The more ice enters the ocean as these glaciers move quicker across the land towards it, the faster the sea level rises.
