Climate Change: rising sea levels
This issue is already being faced in many of the world’s cites....
Should we protect them?
Should we stop allowing new construction in these areas?
Any thought or ideas?

A huge #2. Where will the millions in Bangladesh go as the water level rises?

@StarvingArtist Immigration policies don’t stop invading armies.
People need to be aware of the risks posed by climate and geology when they buy or build, and I don't think that taxpayer money should go into obviating that risk even though that may make private insurance prohibitively expensive for many.
For many sites, public interest in leaving spaces in their natural states is a factor. Perhaps buffer zones should be public property the way most beaches are.
There are probably some areas where it is technically and economically feasible to augment the geology to protect existing infrastructure, but that I think it unwise to do that without consulting the appropriate experts about the long range effectiveness of the solutions in question.
New construction in areas that are likely to be inundated in the foreseeable future should not be supported with public money.

I have been advocating for the cessation of coastal structures since the 70s. It is a burden on those of us with enough sense to realize that nature doesn't respect property built in her way. Instead we have gov't insurance that allows building in flood zones as long as you have enough money. The cost far exceeds the benefit, buy them out or let them drown, but allow nature to take its course rather than trying to stop her rampage. Go after the cause, not the effect.

The Thames barrier was built years ago and is being used more frequently now

@StarvingArtist And the south of England is sinking while Scotland is slowly rising. The effect of millions of tonnes of ice being removed after the last ice age.
i've lived on vancouver isle for 44 yrs & have yet to witness rising sea levels.

@StarvingArtist ,
i don't think sea levels can rise around the world & we're the exception.
@StarvingArtist ,
no.
Your personal anecdotal evidence pales in comparison to the scientific evidence for sea level rise.
Multiple factors contribute to the varying rates of sea level change around the world. Cold water is denser than hot water. Also salinity, the Coriolis effect, wind and ocean currents, etc. Some areas can actually experience a decrease in sea levels, but the overall global net gain is increase.
@SandBKnox ,
google sea level rise in new orleans.
Yeah,,,,,,BUILD A WALL THERE!....... sorry,,,,,,,,,,,

@StarvingArtist I'll try not to yell next time. I'm just frustrated. At least I didn't swear........
@StarvingArtist And would'nt it be great if they could incorporate some wave generators in the wall?
Many of the major cities around the world will have to move up from the current shoreline or riverbank. Planning now seems sensible

Miami is installing check valves on sewer lines and installing pumps to pump water back into Biscayne Bay.

@StarvingArtist to save florida the ground level will need building up by several feet - and that is a lot of rubble
@StarvingArtist We probably should have done that in New Orleans quite a while ago.
Miami has trillions of dollars in buildings and homes. If they don't hold back the water it will be an expensive disaster. @StarvingArtist
Florida has serious problems. They have to decide to spend big bucks to try and protect the cities or take a huge loss by abandoning under water cities. @ShadowAmicus
If they decide to abandon areas to the sea, there will be millions of people who will need to be relocated. Many will be financially ruined if they lose their homes. @StarvingArtist
@StarvingArtist, @Trajan61 New Orleans should have done what Galveston did in 1900. Galveston raised the entire Island by 12 feet, much more fill than New Orleans would take.
@StarvingArtist, @Trajan61, @nicknotes Baytown Texas tried the dikes, pumps, and some fill, finally the Feds and state offered a buyout at the value before the subsidence began. High up front cost, but long term savings. It will be far more expensive to allow the people to stay.
REAL flood insurance premiums...at "cost", NO subsidies...

I agree...if I decide to live in a low lying area that might be flooded, I should pay higher premiums...unfortunately, there are many in lower incomes that can't...I am thinking of the many barrios along the coasts of Miami and other ocean communities...where will people live?
@thinktwice inland
@StarvingArtist Japan is already preparing a 30 year plan to deal with rising waters on their coastline...they have a lot of experience in housing large populations in modern and safe buildings but they will take time to build so they are starting now...we can't even get a frigging pothole fixed so I am sure we will not be prepared in this country.
@bobwjr Easily said but hard to implement...look at what happened on our coast...families who have lived for generations along the coasts of Louisiana and Mississippi lost their family plots and received little help in relocating...relocating is for the rich...it is the same reason a lot of elderly stay in their homes even if they can profit: they can sell but they can't find affordable housing to buy! Inland is the answer pragmatically, but not financially...unless they want to relocate to...omg...South Dakota...
@StarvingArtist We are so great that we have the "duck and cover" preparation from the Cold War...
@StarvingArtist lol sorry...I tend to use sarcasm a lot and forget my winky emoji...but you seem to know that already! 
@thinktwice A gov't buyout is the best answer for a comperable property along with moving expenses. It solves several problems at once as well as defering costs associated with rescue and rebuilding.
I think many cities are curbing new construction...I know FEMA is not going to help out if people try to go back to the same problem area...
We could use newer technology like they have in the Netherlands and Denmark to help cities retain their historic and cultural buildings...but to keep building when we know it is a problem is a big financial drain on all us..

@StarvingArtist I mostly watch BBC or National Geographic...I enjoy documentaries on new technology and international solutions to global problems...I don't like watching network news as I prefer to formulate my own opinion and not cloud it with bias...I hate trump and his policies independent of the news...lol
