Catastrophic Sea Level Rise
Posted by greg2213 on January 8, 2011
One of the things that might be an issue in guestimates of sea-level rise is the fact that tides change over the years.
CORVALLIS, Ore. – The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately accounted for in most evaluations of prehistoric sea level changes.
Due to phenomena such as ice ages, plate tectonics, land uplift, erosion and sedimentation, tides have changed dramatically over thousands of years and may change again in the future, a new study concludes.
The rest: The tides, they are a changin!
Just to put things in persepctive… (click to enlarge)
A subtle change of about 120 meters (almost 400 feet.) Right side is the present and this goes back 32,000 years. I think Al Gore & Co. are about 16,000 years off with their predictions.
