How much sea level rise?



"Up to 5.3 metres / 17 feet."

From the article:

"West Antarctica is already the continent’s largest contributor to global sea level rise and has enough ice to raise sea levels by an average of 5.3 meters, or more than 17 feet. It’s home to the Thwaites Glacier, also known as the “Doomsday glacier,” because its collapse could raise sea levels by several feet, forcing coastal communities and low-lying island nations to either build around sea level rise or abandon these places"


And it's worth noting, something like 450,000,000 people live within 5m of sea level. This would be absolutely catastrophic for the entire world. A significant contributing factor to European political strife over the past decade has been the arrival of refugees from other regions; and Europe is currently home to about 22 million refugees[0]. It's hard to imagine how wealthier regions will cope with the influx of 450,000,000 refugees (admittedly, many will be staying within their home regions -- but many will likely not).

I saw that, but it doesn't say how much of that is at risk for now or how fast it would happen. The paper has some rates of melting but doesn't translate that into rate of sea level rise.


Northern Europe: (Likely) neutral to negative, due to land rise (from the latest ice age).


But the uplift is a lot slower than sea rise, yes ?


In most of Sweden (except the very south) the uplift is faster than the current projected sea rise.


But it can't be so for the long term, can it?, if projected sea rise is like over ten meters.


As an example: 10k years ago during the last major ice age, Stockholm was 150 meters below the current sea level. The land is springy...

(https://sv.wikipedia.org/wiki/Landh%C3%B6jningen_i_Stockholm - use Google Translate.)

In 2009 a dock needed to lowered by 0.5 meters to keep up with the land rise.


AFAIK there's not the same phenomena in Helsinki. Is it so much less springy across the gulf ?


Seems odd...


where do you get that from? i dont see that in the cnn report nor in the study.


This is a good place to start learning about the phenomenon:

Postglacial land uplift

(https://en.wikipedia.org/wiki/Lantm%C3%A4teriet

Lantmäteriet (The Swedish Mapping, Cadastral and Land Registration Authority) is a government agency in Sweden that provides information on Swedish geography and property.

...

Lantmäteriet was founded in 1628, when Swedish general mathematician Anders Bureus was tasked with systematically mapping out the Swedish Empire and educating new land surveyors under directions from the Swedish King Gustaf II Adolf)
