Miami, the great world city, is drowning while the powers that be look away

Robin McKie in the Guardian (UK): ... "There has been a rise of about 10 inches in sea levels since the 19th century – brought about by humanity's heating of the planet through its industrial practices – and that is now bringing chaos to Miami Beach by regularly flooding places like Alton Road," says Harold Wanless, a geology professor at the University of Miami. "And it is going to get worse. By the end of this century we could easily have a rise of six feet, possibly 10 feet. Nothing much will survive that. Most of the land here is less than 10 feet above sea level."

What makes Miami exceptionally vulnerable to climate change is its unique geology. The city – and its satellite towns and resorts – is built on a dome of porous limestone which is soaking up the rising seawater, slowly filling up the city's foundations and then bubbling up through drains and pipes. Sewage is being forced upwards and fresh water polluted. Miami's low topography only adds to these problems. There is little land out here that rises more than six feet above sea level. Many condos and apartment blocks open straight on the edge of the sea. Of the total of 4.2 million US citizens who live at an elevation of four feet or less, 2.4 million of them live in south Florida.

...Miami and its surroundings are facing a calamity worthy of the Old Testament. It is an astonishing story. Despite its vast wealth, the city might soon be consumed by the waves, for even if all emissions of carbon dioxide were halted tomorrow – a very unlikely event given their consistent rise over the decades – there is probably enough of the gas in the atmosphere to continue to warm our planet, heat and expand our seas, and melt polar ice. In short, there seems there is nothing that can stop the waters washing over Miami completely.

It a devastating scenario. But what really surprises visitors and observers is the city's response, or to be more accurate, its almost total lack of reaction. The local population is steadily increasing; land prices continue to surge; and building is progressing at a generous pace. During my visit last month, signs of construction – new shopping malls, cranes towering over new condominiums and scaffolding enclosing freshly built apartment blocks – could be seen across the city, its backers apparently oblivious of scientists' warnings that the foundations of their buildings may be awash very soon....
