Is the melting of glaciers the only thing responsible for the rising sea level?
Only a small part of sea-level rise is a result of melting glaciers and polar ice caps. A far more significant problem is caused by “thermal expansion” of the water itself as it gets warmer. Most forms of matter (solids, liquids and gases) expand or get bigger as they heat up and seawater is no exception. Because the volume of the ocean is so enormous, even a small rise in temperature results in a measurable rise in sea level.
