Jul 8, 2005 - NASA has taken detailed measurements of global sea levels, and confirmed that they're rising. Not only that, the rate is increasing. During the last 50 years sea levels have risen .18 cm (.07 inches) a year, but during the last 12 years, that rate is .3 cm (.12 inches) a year. Part of this rise is due to the expansion of water as it warms up, and part of it is from increased ice cap and glacier melt. It's estimated that 100 million people around the world will be affected by a one-metre (3.3 foot) rise in sea levels.

There was a time when we had two opposite conditions here in Chicago. The beaches at one time were huge, due to the fact of the low water level, then a short time later we almost lost our beaches to high levels of Lake Michigan.
Gee, the people around the New Orleans area are gonna get it rough.
The project in Al's backyard looks like an observational pier, but in reality, it's an ark in disguise.
I call window seat!
