Cities of the World Sinking


The University of Durham looked at levels of land uplift and subsidence in the British isles since the Ice Age. As the ice retreated 20,000 years ago the release of the enormous weight meant the north slowly tilted up while the south sank down. Scotland is still experiencing this "springboard" effect while southern Ireland, Wales and England continues to sink.

The new study shows that land levels could rise by up to 10cm in some areas of Scotland over the next century, offsetting the effects of sea level rise caused by global warming. But in parts of England, where the land is set to sink by up to 5cm over the next century, it could add between 10 to 33 per cent on sea level rises.

If you've never seen the Statue of Liberty or been dazzled by the lights of Times Square, now's the time. Much like its Thai comrade, America’s most densely populated city is doomed to suffer the effects of global warming. Sitting at the mouth of the Hudson River where it flows into the Atlantic Ocean, this concrete jungle will soon be at a much higher risk of damage from rising sea levels and imposing tropical storms. And unlike the ones bobbing around in a barrel on Halloween, this Big Apple will not float.

Science Daily reports that the sea levels in the New York City area are expected to rise about twice as quickly as sea levels around the world, meaning that Gotham will take the plunge well before the rest of the United States. However, Science Daily says that flooding is just one of the symptoms New York will suffer: "The submersion of low-lying land, erosion of beaches, conversion of wetlands to open water and increase in the salinity of estuaries all can affect ecosystems and damage existing coastal development." Not only will the Empire City be transformed into a wading pool, but it will slowly be washed out to sea.
