The illustration seems misleading—showing increase in sea level starting right outside of a glacier. As discussed in the article, the area of diminishing sea level spans thousands of kilometers far from where a glacier used to be, depending on its mass.
The person interviewed claims that people usually don’t appreciate his points since they’re so counter-intuitive, well right there we have Nautilus not helping that at all.
- mikro2nd 6y agoMitrovica has some videos on YT that probably do a better job of explaining.
- fritzo 6y agoAs I understand it is gravity's inverse square law that makes the effect strongest closet to the glacier and tapering off over a couple thousand kilometers.
- strogonoff 6y agoMy understanding as well. The image, though, doesn't convey sea level dipping for many kilometers around former glacier edge and rising only further away (possibly in another hemisphere entirely)—instead it shows sea level rising immediately at the edge, which doesn't seem to track.
- dangirsh 6y agoI think the image is trying to convey that there's a rising immediately near the glacier due to the tectonic plate lifting up. Then there's a falling due to reduced gravitation. What's not shown would be (much further away) a rising due to increased water volume. I agree that the image is a bit confusing.
- strogonoff 6y agoI think the green line is the sea level after the melting, since it is labeled Final Sea Level. It does not show a fall, only a rise, next to the glacier.
