Despite a rapid local sea level rise rate nearly 3 times the global mean (1.8 mm/yr), 15 of 28 studied atoll islands in the southwest Pacific increased in shoreline area during 2005 to 2015 according to a new study (Hisabayashi et al., 2018). For the 3 islands that experienced extreme shoreline erosion – with one atoll island even “disappearing” – a Category 5 cyclone was identified as the most likely causal factor.
Consequently, the authors conclude that “the dramatic impacts of climate change felt on coastlines and people across the Pacific are still anecdotal”.

What’s wrong with comparing Super Storm Sandy’s devastation with projected sea level rise? They are two different things! One is a storm surge, the other an incremental change in either sea level or land subsidence (sinking) or both. For one we can evacuate the immediate area where landfall is forecast to hit in order to save lives. For the other, we have the time to build dikes and barriers like those in England and Holland, or flood-proof, or move. Super Storm Sandy is not unprecedented, and neither are extremely stormy and erratic periods of climate with catastrophic storms, like the Grote Mandrenke — The Great Drowning of Men — of the Little Ice Age. Let me set some perspective.
