I´ve seen various posts on social media from Puerto Rico where the ocean seems to be swallowing up beaches. What´s going on? It doesn´t seem to be limited to one spot or another, either...I saw pictures from Ocean Park, Dorado, Rincón, Aguada...it was always the same story...some buildings are now literally on the water.

I do remember later in the year being high surf season, like a lot of seasonal surfers would come down around November-December-January.

Anyone know what´s happening at the moment?

Whether or not the waters of the Earth ARE actually 'rising' (due to climate-change) there is literally NOTHING at all, we humans can actually....'do' about it.

Perhaps the only thing at this point (going forward) is for no further-rebuilding or new-construction of any kind, on coastal areas, worldwide.

Looks as if we're all in for a helluva 'ride', from now-on, till Mother-Earth or 'whoever' ('whatever' ? ?) originally put everything in motion, finds a way to put everything into balance again.

One thing for certain, if I were the CEO of a property/life insurance-company, I'd be looking at getting OUT of that business right about now...I cannot see any way in which any of those company's could possibly KEEP UP with all the incoming-claims, which are sure to be rolling-in.

Head to the high-ground, I guess ? ? But then with the increase of tectonic-activity worldwide, I can't see that the mountains/high-deserts will serve as much of a sanctuary either.

I recently read that building too close to the beach causes erosion since the ocean has a natural rhythm where the waves deposit sand, if that's interrupted, that doesn't occur. in many beach towns around the world things like jetties also disrupt distribution of sand preventing beaches from being replenished.

Mitigation efforts, which will take some time, could include reconstructing dunes, planting vegetation and re-injecting sand to replenish the beach. Barreto and her team are wary of constructing barriers because they said it could have a further negative impact on the ecosystem.

CRES "is returning the beach to its natural state. This is what a beach used to be … then it was flattened and that's how we got Ocean Park," she said. "Sand will keep moving. It's going to be constant."

Many in the scientific and planning communities are calling for a moratorium on shoreline construction. Responding to these voices and the problems encountered in the aftermath of hurricanes Irma and Maria, Sen. Juan Dalmau (PIP-at large) introduced Senate Bill 1122 to establish a 20-year moratorium on shoreline construction....Planner and environmental scientist Luis Jorge Rivera Herrera explained that “[climate change] is a determinant factor, but what has worsened or deepened the situation is that throughout the various government administrations, they have allowed construction close to the [island’s] littoral, or nearshore, knowing that the littoral and the coasts have dynamic extensions.”

Rivera Herrera, who won the Goldman Environmental prize, explained that waves need room to dissipate their energy, but when a wave hits a hard surface, such as a concrete wall, it returns to the sea with a lot of strength, which in turn does not allow the sand to settle on the sea floor. This causes the loss of beach or erosion.
