>Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.

>According to the IPCC, sea level rise caused by climate change will increase coastal erosion worldwide, significantly changing the coasts and low-lying coastal areas.

Interesting.

Yes, one of the causes of coastal erosion can be the effects of climate change. But what is the likelihood that the cause, or even partial cause, of this particular coastal erosion is climate change? I could be wrong, but I doubt that that causation is readily provable in this case. Hence some people that value a strong, empirical case for things like this will tend to take it more as theater than science. I personally think that stunts like this hurt rather than help the cause. But that's just my two cents.

When the sea levels rise a significant amount, sure. How much additional coastal erosion does IPCC think we’re getting now, with sea levels up like 4 inches?

My point is that there’s no reason to think that the land Tuvalu has lost has anything to do with climate change. Pretending otherwise is pure theater.
