The Tide Is High - NOT!



Here we go again,  Volcanic islands do subside.  They also rise just before they go bang.

In the meantime, in Vancouver on the Salish Sea by the Global Ocean, absolutely nothing has changed.

We built a high tide sea wall around the city, starting back in the 1930s  It was largely completed when i arrived in the early 70's but still been built.  We thought it such a good idea that we never quit.  We also build protective dikes for delta region of the Fraser river to block natural flooding of the tidal zone.

My point is that we have tens of miles of evidence showing that the sea level has not changed.  I even lived on a bank of glacial till that dropped to the beach zone that was surely 10,000 years old.  That beach zone was sea level so you could see.

The sea level has not changed in geological terms since the Northern Hemisphere lost most of its ice, several thousands of years ago.


The Tide Is High


Young inhabitants of a tiny Colombian island are trying to save their homeland from the rising sea.

The five hundred inhabitants of Punta Soldado, an island off the west coast of Colombia, have had to relocate their houses three times over the last thirty years thanks to rising sea levels. They have become accustomed to building their wooden houses on five-foot-high posts to protect them from flooding, and so that it’s easier to move them further inland. In the last decade they have lost over six hundred yards of shoreline and 198 acres of mangrove. Because of this, extreme weather poses a much greater risk.

“For centuries, they have known how to survive. We are learning from them how to preserve the island from rising sea levels,” explains Ballantyne Puin, an environmental engineer at Cornell University. Puin has been working with the local communities of Punta Soldado to protect the island from the consequences of the climate crisis. Inspired by a similar project in Indonesia, and with the help of young people (40 percent of the population), they have recently built a permeable six-foot-high barrier to conserve soil and help mangroves grow. With the hope of receiving government funding, they plan to eventually expand the project to build a larger barrier.

Today, young people are constantly monitoring the rising sea level, documenting its effects on the soil and the ecosystem, and planting new mangrove barriers to replace those lost to the sea. It’s a matter of survival, as the climate crisis has meant fewer fish and mollusks, endangering the fishing industry. Many are turning to ecotourism as an economic alternative so they won’t be forced to migrate to the nearest big city, Buenaventura, known for its drug trade and crimes.



High tide in Punta Soldado. In September 2023, according to residents, the sea reached its highest level since 2019.


Visitors are shown the "mangrove cemetery," a group of ancient trees that once protected the shoreline, now dead due to coastal erosion.
