> Oddly, sea level will probably go down this far north. Earth is spinning, drawing water to the equator. More mass, more gravity pulling water to the equator, along with less mass at the poles to offset.
Can you provide a reference or show some workings which demonstrate that statement to be true? I've not heard this before, and it's not obvious that it should be true.
- jfoutz 9y agoHere's one. http://harvardmagazine.com/2010/05/gravity-of-glacial-melt http://harvardmagazine.com/2010/05/gravity-of-glacial-melt Wikipedia eqitorial bulge has some info as well.
- rripken 9y agoI'm unconvinced. I don't see anything in the harvardmagazine article that suggests sea level fall in Northern California. The wikipedia page explains that equatorial bulge has been decreasing. I'd expect ice-melt to add mass along the equator and further slow rotation which should further reduce equatorial bulge. I'm not saying you are wrong its just that your references don't explain your contention in a way that I can make sense of.
- jfoutz 9y agoI'm wrong. edited the main comment with more references.
- calebsurfs 9y agoCalifornia isn't an area where sea level will go down, ironically it will go down near Greenland and Antarctica due to less gravity from ice sheets. There are some nice maps towards the bottom of this article: http://onlinelibrary.wiley.com/doi/10.1029/2012GL053000/full http://onlinelibrary.wiley.com/doi/10.1029/2012GL053000/full Since Florida is near the equator, facing the same ocean as Greenland, and has subsiding land, it will likely experience more effects of sea level rise.
