2. What Is it? It is the increase of the level of the sea due to the thawing of Antarctica and when the waters from such sources as melting ice of the glaciers flow into the ocean. It is the thermal expansion of the water of the oceans. As the temperature of the oceanic waters increases, the seas become less dense, occupying a surface of the planet. Increasing temperatures result in sea level rise by the thermal expansion of water and trough the addition of water to the oceans from the melting of continental ice sheets. Thermal expansion, which is well-quantified, is currently the primary contributor to sea level rise and is excepted to be the primary contributor over the course of the next century.
3. What produces such increase? This increase is fundamentally due to the thermal expansion and to the loss of mass of glaciers. It takes place fundamentally in Antarctica
