Do people building as close to the Mersey and in the and in the docks as possible understand that their lower stories will very likely be underwater in 100 years?
Liverpool One. built largely on the original pool seems vulnerable and Everton's new stadium will be looking pretty soggy too.

Do you think modern buildings last 100 years? There are plenty that have come and gone in my lifetime yet many temporary structures built during WW2 and Victorian properties are still solid.
Embankments will be built if necessary, they may choose to dam the Mersey as that would also protect Garston, Ellesmere Port, Widnes, Halewood, Mickle Trafford, Little Stanney, Stanlow, Sutton Weaver etc which are also reported as high risk before 100 years. There isn't much River Flow down the Mersey so that could be pumped out.
The bigger problem than sea levels is wave heights which are much harder to defend in immediate vicinity to the coast.
There are still a lot of things going on that are not understood, the experts are changing theorems on a regular basis, which they should, but it would be good if at least one theorem stuck around for a while.
I see the Liverpool City Region environmental plan relies quite heavily on encouraging salt marshes as a means of carbon capture to achieve Net Zero in a remarkedly short time, I can't wait to see how that pans out into reality.

The dam plans are all located around rock Ferry/New Ferry and won't do anything to protect Liverpool.
I think its coming a lot quicker than anyone thinks. A tide Gauge in Savannah recently showed a 7" rise since 2010. This is the biggest but all gauges on the East coast of the USA are showing comparable rises. The rise is not uniform, for a variety of reasons. Liverpool might be lucky, but equally it might not.
I can't see Embankments doing much to help. A back of an envelope calculation of how much the sea level will rise if all land ice goes shows a rise of 70 to 100 metres. I can't see much of Liverpool being visible if that's the case. I don't think the Canute policy has a snowflake in Hell's chance of working.

Stats on ice are often greatly obfuscated eg using area not volume, segregating sea ice and land ice etc, it makes it difficult to form an opinion at to what is exaggeration or misleading.
There are additional complex factors such as the land bounce-back when sea levels rise, the partial flotation reduces pressure.
There is also very little information on the effects of tectonic movement on sea level.
I know the predictions are struggling but of course air pressure, air movement, salt movement and gravitational changes of other bodies etc all affect the distribution of water and its only relatively recently we have figures that could truly be called mean sea levels.
I think it fascinating that we have huge tidal range differences within the UK, Bristol and Liverpool are huge, Mull of Kintyre is tiny. From a basic map the reasons are not obvious and over time you'd expect scouring/deposition to have levelled depth and hence ranges.
