I am always confused as to why they don't include a graphic that shows how a melting glacier or ice shelf translates into worldwide ocean level rise. The common intuition is that Earth's oceans are vast so any amount of above sea level mass going into them isn't going to change sea level that much. I haven't yet seen a graphic yet that explains the calculation, and I'm left cynically thinking that they are mistakenly using a Mercator projection when calculating the contribution for Greenland. https://en.wikipedia.org/wiki/Mercator_projection#/media/File:Worlds_animate.gif https://en.wikipedia.org/wiki/Mercator_projection#/media/Fil...
