Greenhouse gases in the atmosphere keep it warmer than it would be without them. Heating from the Sun controls the average temperature of Earth. Increased temperatures melt ice sheets more quickly, moving more water into the sea, making sea levels rise. More sea ice melts in summer, but this does not add water to the sea or raise sea levels. Warmer oceans and seas expand, causing sea levels to rise.
