"Of over 13,000 islands examined, approximately 12% experienced significant shifts in shoreline positions. The total shoreline length of these islands approaches 200,000 km, with 7.57% showing signs of landward erosion and 6.05% expanding seaward. Human activities, particularly reclamation and land filling, were identified as primary drivers of local shoreline transformations, while natural factors have a comparatively minor impact. "
It's very likely that we're already beyond some of the tipping points, and others are very close[0]. We're basically going into the mitigation phase now by my understanding.
If we lower the CO2 levels (carbon sequestering) and cool the planet by reflecting more sunlight (SO2 injection in the stratosphere), I'm sure these alleged tipping points will be tipped back again, given some time.
It's good to be aware that doom sells, and the incentive to publish doom predictions for the money they make is very high. Of course, they can still be true...
And in 1000 years it will be different again. What’s your point? The fact it has and will always change doesn’t change anything about what’s happening now.
We can choose to mitigate the change or make it worse for ourselves.

The island is certainly in the risk zone, but I think that is also unknowable.
My guess is that by carbon sequestering and/or SO2 injection in the stratosphere, the climate change will be controllable within a few decades.

I'm quite skeptical.
If we lower the CO2 levels (carbon sequestering) and cool the planet by reflecting more sunlight (SO2 injection in the stratosphere), I'm sure these alleged tipping points will be tipped back again, given some time.

We'll see how it goes :)

We know from studying when volcanoes spew SO₂ to the stratosphere that is breaks down by itself over 1-2 years.
So if it somehow causes some unforeseen bad effect, we just have to wait a while as it goes away.
And in 299 years the climate may have changed again, as it is wont to do (and has always done).
And 65 million years ago an asteroid detonated with the power of all of the world’s nukes combined, so there is no need to worry about nuclear war.
And timespans are like that for climate too, millions of years not 299
The little ice age lasted from 1300 to 1850 [0], so 299 years is not orders of magnitudes off.

Is that a subtle attempt to argue that climate is changing on it's own, and not by human agency? Say it if you mean it.
