The Antarctic ice sheet is growing at a rate of about 2 centimeters (0.8 inches) per year. This is due to the fact that more snow falls on the ice sheet than melts. The ice sheet is melting at a rate of about 1 centimeter (0.4 inches) per year. This is due to the fact that the oceans are warming, which is causing the ice sheet to melt from below.
The Antarctic ice sheet is an important part of the global climate system. It helps to regulate the Earth's temperature by reflecting sunlight back into space. The ice sheet also helps to store carbon dioxide, which is a greenhouse gas. If the Antarctic ice sheet were to melt, it would cause sea levels to rise by up to 60 meters (200 feet). This would have a devastating impact on coastal communities around the world.
