If Angus is right, my house will be underwater at one point. I live on the Intracoastal, after all.
Well, who knows? I'm just quoting others, by the way.
The IPCC published in 2013 a prediction of 0.15 to 0.35 meters by 2100. These predictions assumed a certain rate of mass loss from glaciers and the Greenland and Antarctic ice sheets. In 2014, the National Climate Assessment predicted 1 to 4 feet by 2100 and the RPC45 model predicted up to 1.3 meters by 2100. One model predicts up to 12 meters, although that one makes some extreme assumptions. I like the five-foot number for city planning, even though it is sort on the high side.
There are lots of interactive maps you can play with to see what the coastline looks like for various sea level increases. Here's one from NOAA that lets you go up to five feet. There are others that let you take it up to 21 meters.
Of course, if all the ice on the globe melts, then here's what North America looks like:
I don't think any models are predicting this scenario.
And if the sun expands to 3x its current size we all die as well.
Thats about on the same level as 'all ice melting'
Once we get back into a -AMO regime you'll see a recover in Atlantic side Arctic ice like the PDO did with the bering straight. Antarctic ice had another runaway year and positive feedback loops will begin to reinforce thickness down there as well.
Continue on though about how florida is going to be completely underwater soon (although im sure no one would be upset anyway)
