Over time, glaciers advance and retreat, due to climate fluctuation. /* Archives 200x200 */ Melting glaciers, dwindling sea ice, rising global temperatures, and rising sea levels. Once in the atmosphere, these gases stay there for thousands of years, absorbing the heat that comes from the Earth and re-radiating it back to the surface, enhancing Earth’s natural greenhouse effect.
