Tuvalu is sinking

Teaky aside......

Pacific Islands sink.
All these sorts of islands are volcanic in nature.
Volcano erupts forming a china cap.
Coral fringe reef forms around china cap. 
China cap settles or sinks back into the magma chamber.
Lagoon forms or appears between sinking china cap and fringe reef.
Eventually the china cap completely sinks down enough that the island formed by that volcano no longer exists.
Fringe reef and sand associated with that fringe reef erodes away.
They will all sink eventually to be replaced by new volcanos.

It isn't exactly caused by sea level rise or climate changes.

Thisse wase alle covered in epissode of Gilligans Islande.                                  :)

They also move...........if you look at the very old charts and compare to modern GPS positioning.

Every earthquake moves the Islands as the Earth's tectonic plates move.

This slowly....very slowly moves the Island off the volcano that formed it so it eventually sinks.

The problem isn't rising sea levels from global warming but that we have people wanting to live in places that used to be uninhabitated. Don't forget that everyone living there emigrated there.....including the ancestors of the pacific islanders.

This goes for every coastal settlement in the America's, Europe, Asia or Oceania.

There are no native species on Hawaii.

Just thought I'd add a bit of obvious to the discussion.....

Is that from the documentary on Netflix called "The Island President"? If so, that sinking island was in The Maldives.

It likely doesn't matter too much the cause ... climate change may be a contributing factor along with natural island making processes. The problem is that these people in Tuvalu, Maldives, Kiribati, etc. tend to be impoverished because the global client-state economy often bypasses them.  In some cases, the poverty is thrust on American citizens in Saipan, Tinnian, Guam, Puerto Rico, USVI and American Samoa due to long-standing and profoundly racist laws like The Jones Act. I assume that Britain, Australia, Indonesia and New Zealand have similar problems with their own island possessions. In the USA we have actually (shamefully) removed U.S. citizenship from the families of Americans who have fought and contributed selflessly in the U.S. military. https://www.aclu.org/news/voting-rights/nationals-but-not-citizens-how-the-u-s-denies-citizenship-to-american-samoans/

The debate as to why these people suffer isn't all that important in my opinion, rather that they deserve some level of economic protection that they do not currently receive. Workers in Saipan often aren't even protected by U.S. worker safety and wage laws!

Whatever it takes to put this on the radar.

Well yes, they move. But a good deal of the error has to do with the original surveys themselves as not being 100% accurate. Most charts of the Pacific are from hundreds of years old Dutch surveys. Taking a series of fixes and plotting say the entrance channel to Bora Bora's lagoon, you are lucky if you are within a half mile, let alone spot on relative to WGS 84.

I mentioned this in another thread but Admiralty charts actually give you the coordinates offset....sometimes. DMA charts give you a warning that the channel entrance is knowing to be wrong..... sometimes they might tell you by how much and in what direction.

Ya, like those early surveys that showed all the containers as 1 big plate

Just an error caused by solar storms on tracking instruments

This gentleman is from Tuvalu. I believe he is the foreign minister, who decided not to attend Cop26 because of Covid, so instead held this press conference. This picture was in the news a couple of days ago.

just for info: coral growth could keep up with the slow subsiding of the volcanic edifice for millions of years. In Moruroa atoll, when drilling down, they basalt >1mile below the lagoon.

I guess coral growth could keep up with SLOWLY rising sealevels too (slowly!), as long as high water temperatures do not kill the coral

Unfortunately the ocean acidity is also rising due to increased atmospheric CO2. A bit difficult to leave an exoskeleton in carbolic acid.☹️

Takuu or Mortlock Islands (nasa photo). The dark patches on the right are dry land. The remainder is submersed, the 2 navigable entrances to the lagoon are on the left. The lagoon is 5-8 metres deep and roughly 8km across. 30 metres off you're in a 100 metres of water. It's not sinking or sliding. It's eroding.

Yeah, I read fufkin's response, duplication unnecessary. 

This was the original publicity stunt from Mohammed Nasheed in the Maldives ...

Tuvalu has actually gained land mass by some 2.9% in the last 40-50 years.  But most will never hear that from the mendacious mandarins of the wannabe ruling class.

What's interesting is that most (74%) of Tuvalu's islands/atolls have gained area through coral accretion but 26% have lost area due to erosion.  Also interesting is that local sea level rise is about twice that of the global average.

Here's some recent peer reviewed science.
