More maps from the same series

so bummed to find out the little poky house I grew up in would have a shoreline lot on the Isle of Skyway what an investment

this is very cool. thanks for posting!! Glad to see that the Isle of Wedgwood survives and that I won't be treading water ( at least for a while...)

I will be willing to sell you some waterfront in Issaquah and Port Orchard

240' of rise if all the sheet ice melts? something seems off with that....

like i said, 240' vs. 216' = big difference in volume. thanks sluggo

The snark aspect of the let me google that for you link was aimed at the maker of the map. Some of the other maps in the series are based on 250 ft, or 260 ft.

it's all good

Near as I can tell from looking at various maps and a GPS is that the 250 contour line passes through our living room. I think we're good.

One thing those maps don't account for is changes in land levels due to removal of the weight of ice from the land. Probably not a big factor around Seattle, but could be more significant in northern BC, SE Alaska -- nothing in Florida. I recall reading about some discoveries of ancient villages now deep underwater -- much deeper than the rise in sea levels from the melting of ice sheets during the last ice age. It seems that the weight of ice on the continent caused the land along the BC coast to be pushed up. LINK I think a whole bunch of other stuff will happen if trends continue and more and more ice melts. I think the understanding of the mechanisms of ice age / warm period cycles is imperfectly understood -- one hypothesis I've read supposes that at some tipping point during a warming period prevailing wind currents reverse (e.g. the winds that generally circulate counter-clockwise in the Pacific basin would circulate clockwise) and being a new ice age cycle. Under that scenario downtown Seattle might receive as much or more snowfall as Paradise on Mt Rainier does currently. Adding more CO2 into the mix will accelerate the current warming trend (warming since 15,000 ago) and how it will affect civilization is unpredicatable -- but perhaps flooding Florida and drowning millions of retirees is part of a plan for keeping the Social Security trust fund intact without raising the income limit by conservative lawmakers.

Here's a neat idea: Instead of letting all those skyscrapers go to waste, lets fill their first 20 floors with concrete, raising the level of the floor as the sea level rises. Outside we build floating sidewalks with bridges between streets, and turn Seattle into the new Venice!
