Australia throws life preserver to Tuvalu's future climate refugees

If the country disappears under the waves, do they get to keep their internet suffix (“.tv”) and the revenue from it?

Low-lying atolls are pretty good at adapting to sea level rise. Studies have shown that most of them have increased in area over the decades. For example (Funafuti is the capital of Tuvalu):

Coral islands defy sea-level rise over the past century: Records from a central Pacific atoll

Abstract:

The geological stability and existence of low-lying atoll nations is threatened by sea-level rise and climate change. Funafuti Atoll, in the tropical Pacific Ocean, has experienced some of the highest rates of sea-level rise (∼5.1 ± 0.7 mm/yr), totaling ∼0.30 ± 0.04 m over the past 60 yr. We analyzed six time slices of shoreline position over the past 118 yr at 29 islands of Funafuti Atoll to determine their physical response to recent sea-level rise. Despite the magnitude of this rise, no islands have been lost, the majority have enlarged, and there has been a 7.3% increase in net island area over the past century (A.D. 1897–2013). There is no evidence of heightened erosion over the past half-century as sea-level rise accelerated. Reef islands in Funafuti continually adjust their size, shape, and position in response to variations in boundary conditions, including storms, sediment supply, as well as sea level. Results suggest a more optimistic prognosis for the habitability of atoll nations and demonstrate the importance of resolving recent rates and styles of island change to inform adaptation strategies.

It is pretty easy to be sanguine about sea level rise when you’re sitting high and dry.

It’s like building your house in a flood plain. Might be beautiful area but sooner or later the dice will roll snake eyes.

From the article.

Dr Kench said in areas where coral reefs were healthy, enough sediment was being produced to cause islands to grow.

The first linked article noted that the sediment being deposited is a mixture of coral, sand and gravel. Storms and tropical cyclones (typhoons) in particular generate new gravel deposits.
