I know you cut off the data at +14m to save (expensive) disk space. But lots of us are now discussing rises of more than 14m. Greenland’s ice is melting fast enough to water London already, and its ice would add 7m. The West Antarctic Ice Sheet would add 5m. But the entire Antarctic melting would add not 5m, but 61m. That’s 68m of predictable (if not actually inevitable) rise, on average. Plus tides differ globally, so the bigger range would cover tidal additions, too.

Disk space is a lot cheaper since you published this excellent tool a couple of years ago. Do you think you could add back the missing data now?

FWIW, did you think to delete just all the elevation data that’s farther than, say, 500Km from a coastline, or surrounded by elevations larger than 100m? That might save some space from data that represents land that can’t be flooded. And also data for the seas themselves, which are already flooded. Maybe you have, but maybe that would help minimize to accommodate greater elevations along the coasts.

Thanks again for the great tool.

By the way, thankyou very much for creating this sight. Ive had 10 weeks to complete this Geography project on sea level rse in spain, and this is the last week and i havent even started it yet. Thanks to this sight I can!

But, I do hope that this anticipated world flood will make you rich, or whatever. I know of several domestic companies working hard to develop a tool just like yours, but you obviously beat them to it. The result of your hard work is an eye opener, a time machine and damned good entertainment. May we all live to witness Gaias revenge - It’ll be the greatest spectacle in 55,5 million years. We should all consume more to contribute to the greenhouse effect and thereby speed up the melting process. That way we could better evaluate the quality of this ingenious piece of programming.

Private jets and SUV’s for everyone!

Peace X-)

I am new to this issue and I have a problem. Can some one direct me to data that is direct measurements? This must be a really difficult measurement to make. The constant movement of the tides must make this difficult at best.

I am sure NASA is measuring this but I cannot find a reference.

Thanks

Thanks, chaps, for an intriguing and thought-provoking discussion. Quite relieved I don’t live in Bristol, but that has nothing to do with the potential to flood……… only kidding.

Anyway, the discussion is really useful too - thanks everyone. Weird that so many of us are from the Bristol area though. I notice that with high enough rises, W-S-M becomes an island - I wonder if it’s possible to apply for shipping rights in advance?

Joking aside, I do hope you’ll do more with this - get some press, then get some commercial help (maybe you can protect your work and license it? Usually IP firms will give you a 1/2 hour interview for free). It would be worth making this more robust, with worldwide coverage, more server power etc etc, keeping it free (like Google) but making it commercially viable with ads and / or donations, and making it much better known - everyone should see it!

All these things take money, but you should really seriously consider going for it. Have a look at metcheck.com - I have nothing to do with them, apart from being a user of their service, but they’re a neat example of some guys with brains who managed to make a business from their hobby - and of course they have brought us all better weather forecasting, for free.

Good luck!

Certainly the tides will have a great impact I should imagine, particularly in the Bristol Channel, currently at Clevedon I have noted the water over the top of the landing stage on the pier on a high spring tide, what would be amazing (but would probably take forever) is if there were a way to include coastal erosion as a factor i.e. different types of rock take differnt periods of time to erode.

As this has the 2nd highest range in the world.
