Thanks.
I have problems imagining how #sealevel rising by a few centimetres can be a problem for societies.
Yes, by now I know that corrosive saltwater is bad for built infrastructure and drinking water pipes and such, and that soil inundated by saltwater becomes unusable at some stage for growing veggies.
But how bad is this? What's the scale, what's the temporary tech fix, if any?
I have no idea.

Now I saw someone doing this simple equation:
50cm (global) #sealevelrise on a beach with 30° angle means 86cm less beach.
A beach with a 15° angle loses 186.6cm.
Don't know whether this is correct.
But our beach where I live is very shallow before it gets into higher, steeper dune landscape. I guess, 50cm from an AMOC collapse basically vanishes the beach within 150years.

That is, if the global 50cm rise were be the same at our beach! ... can't imagine how this would play out for real...

"To protect the low-lying areas in Changi and the Greater Southern Waterfront from flooding, a study has proposed building coastal protection structures to form a “continuous line of defence”, with construction set to begin in the 2030s, national water agency PUB said on Saturday (Aug 30)."

Coastal barriers, shoreline upgrades among proposed moves to shield southeast Singapore against rising seas

The proposed coastal protection measures will complement the previously announced Long Island at East Coast to provide a continuous line of defence, said national water agency PUB.

Wenn ich es gestern richtig verstanden habe, ist die Zukunft des Sealevels ab Oktober ungeklärt. Es ist ein wirklich großartiger Ort mitten in der Stadt. Stimmt mit euren Füßen ab und guckt mal dort vorbei!

Study finds #sealevel projections from the 1990s were spot on
A new era of monitoring global sea-level change took off when #satellites were launched in the early 1990s to measure the height of the ocean surface. This showed that the rate of global #sealevelrise since that time has averaged about one eighth of an inch per year. Only more recently, it became possible for #NASA researchers to detect that the rate of global sea-level rise is accelerating.

Polar ice sheets vulnerable: +1.5°C warming risks meters of sea-level rise. Current +1.2°C already a threat. #Climate #IceSheets #SeaLevel

Warming of +1.5 °C is too high for polar ice sheets - Communications Earth & Environment

Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level rise, meaning that only a return to +1 °C or lower will avoid extensive loss and damage to coastal populations, according to a synthesis of recent evidence.
