But just think of the new beach front properties!

The rise in sea level could be doubling its speed.

Der Spiegel:
"A special report prepared earlier this year by the German Federal Scientific Advisory Committee on Global Climate Change (WBGU), found that "a sea level rise is part of the inescapable physical consequences of global warming." Some of the key points made in the report include:

  • At the peak of the last ice age some 20,000 years ago, the sea level was roughly 120 meters lower than it is today; the global climate was colder by four to seven degrees Celsius.
  • During the last warm period, the Eemian interglacial era of 120,000 years ago, the world was roughly one degree warmer than it is today; the sea level was approximately two to six meters higher.
  • Three million years ago in the Pliocene era, when the earth was two to three degrees warmer than it is today, sea levels were 25 to 30 meters higher.

We are still far away from anything close to a 30-meter increase in the water line. But on the flipside, there is a considerably greater danger of storms and floods in London, New York and other cities in the coastal regions of the North Atlantic. Some coastal cities could even sink completely this century, a study found early in March this year."
