21 FEET is a bunch of B.S. You are the one thats appears anti-science and prone to hysteria. Future sea level rise Tide gauges and satellite altimetry suggest an increase in sea level of 1.5-3 mm/yr over the past 100 years. The IPCC predicts that by 2100, global warming will lead to a sea level rise of 110 to 880 mm (details below). en.wikipedia.org 17. Over the last 100 years, the global sea level has risen by about 10 to 25 cm. Sea level change is difficult to measure. Relative sea level changes have been derived mainly from tide-gauge data. In the conventional tide-gauge system, the sea level is measured relative to a land-based tide-gauge benchmark. The major problem is that the land experiences vertical movements (e.g. from isostatic effects, neotectonism, and sedimentation), and these get incorporated into the measurements. However, improved methods of filtering out the effects of long-term vertical land movements, as well as a greater reliance on the longest tide-gauge records for estimating trends, have provided greater confidence that the volume of ocean water has indeed been increasing, causing the sea level to rise within the given range. It is likely that much of the rise in sea level has been related to the concurrent rise in global temperature over the last 100 years. On this time scale, the warming and the consequent thermal expansion of the oceans may account for about 2-7 cm of the observed sea level rise, while the observed retreat of glaciers and ice caps may account for about 2-5 cm. Other factors are more difficult to quantify. The rate of observed sea level rise suggests that there has been a net positive contribution from the huge ice sheets of Greenland and Antarctica, but observations of the ice sheets do not yet allow meaningful quantitative estimates of their separate contributions. The ice sheets remain a major source of uncertainty in accounting for past changes in sea level because of insufficient data about these ice sheets over the last 100 years. grida.no

sounds like now might not be the best time to invest in island beach front.

Concord, MA — Declare Energy Independence Just as the famous "shot heard round the world" that marked the start of the American Revolutionary War was fired in Concord, Massachusetts, we may again look back to the Commonwealth as the beginning of a revolution in attitudes on global warming. For it is Massachusetts's challenge to the federal government's incomprehensible policy on global warming that will be heard by the U.S. Supreme Court which may change forever the way we look at global warming pollution. In defiance of the clear meaning of the Clean Air Act, the U.S. Environmental Protection Agency has refused to regulate carbon dioxide and other heat-trapping gases that are the cause of our current climate crisis. It is the Bush Administration's position that these gases that spew from the tailpipes of cars as well as power plants and industry, are not pollutants despite the overwhelming scientific evidence that they are the cause of global warming and the bizarre weather that's just beginning to take its toll. On the same day the Supreme Court accepted this court case, a bizarre tropical weather system drenched the nation's capital, backing up traffic, closing federal buildings and toppling a 100-year old elm tree on the White House lawn. Why the heavy rains? Warmer temperatures mean more evaporation and more humidity that gets released in form of torrential rain. In the spirit of 1776, Massachusetts and 10 other states bravely took it upon themselves to stop this pollution by requiring car manufacturers to producer cleaner cars that are more efficient and cheaper to operate. That's when the federal government stepped in and told them they had no legal authority, setting up the court case that will be heard ‘round the world. Exactly 230 years ago, we declared our independence from British rule. It was self-evident then that there was a better way: Life, Liberty and the Pursuit of Happiness. Today, brave Americans like you are standing up and saying there's a better way: Renewable Energy, Conservation and the Pursuit of a Safe Climate. stopglobalwarming.org
