Good on them. But what a sorry state to be in, when global warming and sea level rise related problems already are a reality in Miami or - of all places - Norfolk's naval base.
Unless I'm thinking of another coastal Virginia city. Anyone from VA know?
The crater is classified as a complex crater and as a result of the impact, the asteroid left a "W" imprint in the surface. The land on the outskirts of the crater(The "W") is unstable and is most likely what is calling the region around Norfolk to sink.
Someone with more geology knowledge might have more to say about it however :)
B) It's a constant problem in Miami where high tide is now above the level of many roads so they've had to jack the roads up several feet more.
C) Venice, Italy is routinely flooded because of sea-level rise and it's only getting worse.
one thing that I don't fully understand yet: there were always storm surges above 2m (?) how come that 50cm sea-rise without any storm surges are already causing problems?
New York recovered from Sandy, but the city would need massive changes if that water level became routine.
No, it isn't. It's a problem during king tides. Yes, king tide flooding is getting worse, but "constant problem" is an exaggeration.
Or you can stubbornly deny this.
Old: ok so 10cm global sea rise + 15cm tide fluctuation, which might well reverse.
I can't believe some cities are built so close to the water when storm surges and natural tide fluctuation over decades is over 50 cm (20'') as seen in Alaska etc. ^^ This statement still holds somewhat.
