re: The Welsh village condemned to disappear due to climate change

Aren't NOLA and Manhattan supposed to have been underwater for 20 years now?

With NOLA, it may have been more wishful thinking than anything.

Google Earth is a wonderful app. It allows anyone to look back in time. For instance, this village, in 1985 looks similar to 2020 in terms of water level.

I would have expected some drastic water level changes between then and 2020. But what do I know.

If true,the Dutch probably had solutions for this, but they are currently being starved to death.

It started as an outpost and was developed as a port on a marsh and is now subsiding, just like New Orleans.

So claiming it will be under water in 2054 is dishonest. If not for that wall and system of levees, it would have been under water in the 19th century. Again - just like New Orleans.

+1. Subsidence does not equal "climate change".

My favorite part of these climate doomsayers is how easily they place the date JUST far enough into the future to be close enough to feel like you ought to worry about it, but far enough out that when the date approaches and frick all has happened they can adjust it out another 20 or so years and the last group who bought the fear will have forgotten/died and a new crop will bite the the new shiny hook.

I think they may have learned this from religious end of the world types who always managed to find some new text lying around that made their last prediction but has super confirmed the newest one...so get ready!!!!

This.

Subsidence is a localized phenomenon. Unconsolidated soils, usually made of manmade fill (i.e. garbage), or alluvium (delta silt which has since become cut off from annual floods) without a solid shallow bedrock will compress over time as gravity squeezes the water content out of the soil, causing it to shrink, and thus, sink. Places with more bedrock or more dense soil will not sink (or sink more slowly) than areas with unconsolidated soils. Places where rivers are continually depositing new soil will actually rise and create more land. Subsidence can also happen in environments with limestone bedrock and dropping water tables. The water table erodes the limestone over time, leaving underground voids. When the water table drops, these voids fill with air, which can no longer support the sediment above the voids, causing them to collapse into sinkholes. This is a huge problem in Florida, particularly.

Climate Change is predicting that melting terrestrial ice sheets will cause sea levels to rise uniformly everywhere by so many inches or feet, inundating low-lying areas first. In this scenario, the sea level is roughly the same everywhere, so while tides may make some differences, the rise is even across the board.

Both of these different threats have different causes and different mitigating measures.

With subsidence, it is a local issue which can be combatted via restoring delta sediment deposition, building flood walls, or through rehydrating underground soils. That last one is interesting as it has been proven that endemic water main leaks in the New Orleans sewage and water system have actually forestalled subsidence in many neighborhoods because the leaks are replacing water that gravity would otherwise be squeezing out.

With climate change, the issue is one of preventing extreme global cycles in temperature that would cause large amounts of land ice to melt. The main way governments have scene to do this is via regulating greenhouse gas emissions, but this is a complex and global problem (assuming it can even be effectively curbed via human behavior at all).

The earth will always change and we have to get use to it. We could all make a living flying around the world on private jets, going to UN meetings to blow hot air up everybody’s b&tt, and contribute to more carbon footprint doing this.
