"If sea level rose 7 metres (20ft)" Topic

Following is a link to a website that has interactive maps that show what would happen if sea level rose by 7 metres. It uses NASA data and Google Earth. There are maps for the whole globe.

Please no comments re global warming, if you want, take it to the CA board, this post is just for interest only.

Interesting, but it is a static model only taking elevation into consideration.

With a rising sea level you'd have way graver tidal effects along the coasts than now, further eating away land.
You'd also have serious effects on tidal waves moving up rivers more often than is the case nowadays, whereas the maps here ignore rivers mostly in that context.

Cool! 7m would put my parents house two streets away from the Thames. If it went up to 10m then they would have a nice riverside property. Unfortunately at the expense of their garden :)

Looks like we would still have to drive up the M18 to get to the nearest sea, but stopping just the other side of Doncaster now. How disappointing, I hoped it would at least wash Rotherham away…

You can't wash Rotherham away!

This troubled world of ours needs The Chuckle Brothers!

Anybody interested in a nice four bedroom terraced house, only 20 km off shore? The chimney is visible, except at high tide.

I live on a hill thats about 1.5km away from a major river – water levels need to rise by 200m to get my feet wet.

Yeah but how you going to get to the shops :)

In my home town, a lot of expensive infrastructure would need work but the city would not exatly be an island. My own house is over 200ft elevation.

At 14m, the province would be an island.

I'm sure that many more serious problems would be going on at that point.

Chick,

Very, very nice!

It is definitely a far cry (and more realistic, I might add)from what I had researched on the subject last couple of times I approached the subject:

Thank you for sharing. I will bookmark the site for future reference.

Houseboats are going to be a HUGE growth industry in the future

I guess that if it only rises 20 feet, I will still be high and dry. However, I'm sure that folks in Galveston and other Texas costal areas will try to encroach.

I hope that increases my property value!

Interesting that the Black Sea, Caspian Sea and Hudson Bay are all modeled for the effects, but the Great Lakes remain utterly static. It'd be nice if the effects could be shown for those – I've never seen them in any sea level change map.

NVDoyle,

Does this help at all?

I think it covers most of the life of the lakes, from the Ice Age to past melts of all North American glaciers.

But, as Schwab says about its investments, "Past performance is not an indication of future results." :)

I'm fine up to 14 meters. If by "fine" you mean "not immediately underwater but still suffering for having a hot, stagnant body of water nearby full of toxic chemicals leached from the submerged heavy industry in Dundalk."

NYC Apartment – OK
Catskills – way OK
Long Island Land – that much closer to beach property

What's Global Warming?

Didn't Al Gore invent that?

Still no beach front!!!!!! Let me know when the 'tide' goes goes up above 20ft…….maybe 5200 ft or so. then maybe fun at the beach.

Cool, no problem and I'm in Galveston County Texas.

I find it amazing how various artificial ponds will have their water level increase.

"Interesting that the Black Sea, Caspian Sea and Hudson Bay are all modeled for the effects, but the Great Lakes remain utterly static. It'd be nice if the effects could be shown for those – I've never seen them in any sea level change map."

I'm not sure modelling the Caspian is terribly valid. The model goes up the St Laurence to Montreal -- I expect much above Lachine you are over 14m above sea level anyway.

At 21 meters my area will be an interesting spot for divers although the slag lagoon toxins from the nearby steelworks may offer a more colourful attraction. The Flintshire bridge will still be visible but the roads on either side will be gone.

Cool I am in Michigan…no impact as it will still suck.

The Great Lakes are all at least 74 metres above sea level (at least, the surfaces are – you can probably knock a dozen or so metres off for the depth of the St Lawrence river):

ghetto edit: Therefore, a 7m rise in sea level will get nowhere near the Lakes.

My "shore" house is 4 ft above sea level.
Not so much if the sea rises by 20!

Well, heck. Learn something new every day.

I was kind of hoping for Chicago to flood, and for northern Indiana to become (more) beachfront.

It looks my house that is 4 blocks from the Atlantic is done. Anyone interested in buying, I'll give you a really good deal.

Tom

Kansas. Nobody here will notice.

I will be 5 meters underwater.. it's touch and go with some spring tides now… :)

I can't see how the Caspian is accurate as I thought it was no link to the oceanic system. It is entirely land locked and fed by rivers. Bloody interesting otherwise though.

Nice find

Tricks

Well… seems I would be living on an island just off the coast of what remains of the Netherlands… Still, keeping my feet dry, unless there's lots of wind… (Noordwijk aan Zee)

Interestingly for the East of England around Lincolnshire and Cambridgeshire thats just about back to where the coastline was in Iron Age/Roman times.

Tricks

Thats a fantastic tool for archaeology you know. Flooding the Witham valley to the east of Lincoln you can see exactly why settlements appeared in certain places alongside the flooded valley. Bardney and Woodall Spa particularly.

Tricks

Duuuuude … El Centro will be under water, and San Diego will be cut off from Arizona. (Sadly, you'll still be able to drive to L.A.)

And my parent's house will be flooded, too.

Oh, man … Sacramento's GONE.

Does a nice job of cleaning up Cape Cod.

I check out other cities I have been to as well as my own (my land is safe), I noticed Sacramento, Vancouver is also going to have a really hard time.

Groovy – looks like my place is good up to 12M. I am, however, going to need a boat at anything over 10M if I want to get to the Dairy Queen for a sundae.

Doug

Cool -- I would live on a groovy island!

Charlestown, MA

And at 14M -- I'm waterfront baby!

Bring on that global warming loving!

Hmm. ZERO meters sea level rise, and my house is still in the blue. Should have stayed in my old house, only floods after TWO meters sea level rise.

"Oh, man … Sacramento's GONE."

Until you climb towards Citrus Heights and Roseville, yup. Of course, Sacramento wouldn't be alone. Most of Solano, and Yolo Counties and big chunks of Sacramento and San Joaquin Counties get submerged as well (not that Stockton would be any great loss). You could probably add significant bits of Sutter and Yuba Counties to the list as well.

Of course, Sacramento used to flood regularly. That's what all that canal and levy between Sacramanto and Davis was built to prevent.
