On Shishmaref Island in Alaska, homes are being washed into the sea. In the South Pacific, small island nations face annihilation by encroaching waters. In coastal Louisiana, an area the size of a football field disappears every day. For these communities, sea level rise isn't a distant, abstract fear: it's happening now and it's threatening their way of life. In The Rising Sea, Orrin H. Pilkey and Rob Young warn that many other coastal areas may be close behind. Prominent scientists predict that the oceans may rise by as much as seven feet in the next hundred years. That means coastal cities will be forced to construct dikes and seawalls or to move buildings, roads, pipelines, and railroads to avert inundation and destruction. The question is no longer whether climate change is causing the oceans to swell, but by how much and how quickly. Pilkey and Young deftly guide readers through the science, explaining the facts and debunking the claims of industry-sponsored "skeptics." They also explore the consequences for fish, wildlife--and people. While rising seas are now inevitable, we are far from helpless. By making hard choices--including uprooting citizens, changing where and how we build, and developing a coordinated national response--we can save property, and ultimately lives. With unassailable research and practical insights, The Rising Sea is a critical first step in understanding the threat and keeping our heads above water.… (mais)
A shortish (200 pages) look at the problem of rising sea levels. It raised a lot of interesting points that I hadn't thought of. The causes and scope of rising sea levels were covered well, but the authors barely touched on the consequences for large urban areas like New York, Tokyo, and Singapore. They strongly advocate "strategic relocation of infrastructure" (moving inland), instead of barriers and beach replenishment, which are extremely expensive and resource intensive, are not sustainable, and cause more problems in the surrounding areas.

The Rising Sea distinguishes itself amid the recent outpouring of climate change books with its tight focus, which is on the human consequences as oceans levels climb. Geologists Pilkey and Young forecast an "inevitable" rise in the global sea level of as much as 7 feet over the next 100 years.
Careful descriptions throughout the book of how rising seas are likely to affect particular locales give the predictions a human dimension and illustrate some of the attendant threats that will have to be considered, among them shoreline retreat, salinization of water supplies, and storm surges that could force the abandonment of entire island nations, such as the Maldives.

During the past 2.5 millions years, massive continental ice sheets advanced and retreated many times across planet Earth's northern hemisphere. With each advance, the amount of water bound in ice increased, and the level of the sea dropped. With each retreat of the ice sheets, meltwater was released, and the level of the sea rose. Over this tie, ocean level has fluctuated across a range of more than 500 feet (150 m.), and shorelines have moved landward or seaward tens of miles as a result. In fact, sea level change has been a constant part of earth history as there has been an ocean. -Preface
A rising sea is not something that may happen in the future. It is already upon us. Planners turned down construction of a large residential development on the York Península, South Australia, because it would be flooded by rising seas. In England, regulators declared six small villages on the Norfolk Broads northeast of London will need to be abandoned as sea level rises. To avoid the rising sea, the 580 Inupiat Eskimo inhabitants of Shishmaref, Alaska, will likely be moved to the mainland at a cost of several hundred thousand dollars per resident. On barrier islands along the Pacific Coast of Columbia where the sea level is rising with particular rapidity (because the land is also sinking), moving buildings and entire villages to higher ground is already a routine matter. In rural Cape Town, South Africa, a "blue line" may be established seaward of which nothing can be built because it would lie within an expected flood zone from sea level rise. Plans to abandon many Pacific atolls are now on the drawing board because they will soon be flooded by the expanding oceans. And in South Carolina, retreat from the shoreline is response to the sea level rise is now official state policy. -Chapter 1, Living on the Edge

"maybe people who insist on building adjacent to eroding shorelines facing the open ocean should be considered fools rather than victims?"
