Our dynamic planet has an apparent paradox: the more ice melts from landlocked glaciers, the lower the sea level gets in nearby areas. How does this happen? Through the physics of isostatic rebound, when the surface of the planet acts as an elastic sheet dimpling and rebounding under changing loads.
Rising sea-levels will someday put several American cities completely, or partially, underwater. Here are the U.S. cities that could be submerged by sea-levels in approximately 200 years—and what you can expect for your own city in the future.
If we burned all the coal, oil and gas that’s left in the ground, we’d melt Antarctica and global sea levels would rise as much as 60 meters (200 feet) over the next ten thousand years. Coastal cities from New York to Shanghai would wind up deep underwater.
There are about 330 million cubic miles of water in the world oceans today, 97% of all the water on the planet. Early in our planet’s 4.5 billion year history, water from the atmosphere and from the interior of the Earth gradually collected in the low areas on the planet’s surface to form the ocean basins,…
Most of us have probably never given a second thought as to how sea level is determined. It's basically where the ocean starts, right? Not even close. It turns out there are countless factors that have to be taken into account because the oceans simply aren't at the same level all around the world.
The Intergovernmental Panel on Climate Change has this morning a landmark report which places the blame for climate change squarely at the feet of humankind.
As sea levels rise, an extraordinary population shift will place immense stress on cities around the world. Where will global warming refugees go? One design team envisions an "Embassy of the Drowned Nations" to provide asylum, and a fresh start.
