Yet, there is tremendous force, applied without rest.

Not in all cases.

On the other hand, the sea walls at Sendai and Mirimasu(sp) were piled
up like a bunch of children's blocks. You also have the problem of
scouring eating out from below such walls, as was seen in Katrina. The
difference between a tsunami wave and a storm surge is that the
tsunami waves are fewer, larger, and more powerful.

There has been a sea rise of something like 9 cm in the 20th century.
Whether man caused or not is up for debate. Whether this is the normal
breathing of the planet, who knows. Our records don't go back far
enough to really know.

There is increasing evidence that a tipping point could be reached
where things could shift rapidly. The big problem is Antarctica and

The bogus part, IMHO, is the proposed solutions. Let's send money to
Africa to combat global warming. That's silly. Let's open an exchange
to buy and sell the right to pollute. Garbage. If it's a real issue,
then let's work on carbon dioxide sequestration. That's nature's
solution. It's called fossil fuels.
Now, the degree of the problem is politically amplified to an extreme
degree. Interestingly, the first person to take political advantage of
global warming was the very conservative Margaret Thatcher. Go figure.
