Coral islands defy sea level rise

The uncertainty of science: Despite having some of the highest rates of sea level rise in the past century, the 29 islands of Funafuti Atoll in the Pacific show no signs of sinking.

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.

Be aware as well that the cause of the rise in sea level here is not clearly understood. It could be the global warming we have seen since the end of the Little Ice Age of the 1600s, or other more complex factors.
