Some background and caveats first…

Now we think that those nice people at the Environment Agency are a bit shy with their flood maps so we went in search of something that sums up what we’ve been saying on our Flooding and Portsmouth pages – but without the insomnia factor.

We found this site generated by quite a clever person which crosses Google mapping with some lovely NASA orbiter holiday snaps and comes up with something really rather useful and er…worrying.

Now the map ignores the presence of sea defences but then again the sea levels are median tide (that’s midway between high and low to you and us). As you probably know Portsmouth has quite a tidal range thus in many areas these two variables may well cancel each other out.

If you want to know more nuts and bolts about the map you can click the “about” link when you get there. You can also go anywhere in the world on the map, zoom in and out and save your co-ordinates.

Finally we’ve set the default link at 7m – that’s the 5m rise that some scientists predict may well occur within a century if we don’t get to grips with carbon emissions fast (and we mean FAST) plus 2m for tide/storm. Now that covers most of Portsmouth in water. We know that may seem upsetting and alarmist and you’ve just had your dinner etc but climate change is very serious. Why beat around the bush?

Finally finally…its not our site so we’re not responsible for the content, the value of sea levels can go up and down and past performance is not necessarily (but quite probably) a guide to the future…

Ready?

Ok here it is…
