The author clearly confused the land ice/ice sheet with sea ice. Do you have evidence supporting your claim that "Melting sea ice can change sea levels by changing the density of the water in the ocean"? I'd be curious to know.

As it warms, the ice in the glass melts, but the total volume of water does not change. However, melting sea ice does contribute to climate change. That’s because white sea ice reflects the sun. So when it melts, the dark open ocean now absorbs sunlight and heats up, raising global temperatures, which in turn cause glaciers and ice sheets on land to melt further. Globally, sea levels have risen four to eight inches since the last century and will continue to rise as the ice melts, putting coastal communities worldwide at risk. http://www.yaleclimateconnections.org/2014/11/loss-of-land-ice-not-sea-ice-more-sea-level-rise/ http://www.yaleclimateconnections.org/2014/11/loss-of-land-i...
