Now let us consider the question of warming: If it is occurring — and I believe it is, based not on disputable temperature measurements but on sea levels, which have risen two inches in two decades —...

I hate to rain on this guy's parade but that's baloney.

Claim That Sea Level Is Rising Is a Total Fraud

Sea levels began to rise 18k years ago at the end of the last glacial period. They have risen about 135 meters since then which is an average of 7.5 millimeters per year. That is an average of 750 mm per century (29.5 inches) which is far more than the average over the last century.

From 1880 to 2000 sea level rose about 20 cm or just under 8 inches. Far far less than the nearly 30 inches per century average over the last 18,000 years.

That is less than 3/4" per decade over the last century. More importantly that is a significantly slower rate of rise than the average for the last 18 millennium.

TE I really like it when people more knowlegeable than I contribute to threads I start. Pretty much everyone. So let us assume that we aren’t getting warmer. That means, excluding Zubrins “earth is warming” opinion, we still enjoy the benefits of more CO2. I don’t get my beachfront property though dammit.

Great post!

Let me add a factoid. Often the other side will tell you
that sea level is accelerating, you know, it's rising faster
and faster every year. And then they run the home page for
Colorado University's Sea Level Research Group as proof
with this graph:



And if you follow the link CU gives you for the data, you
can plot it out for yourself in Excel, but if you use a
polynomial trend line instead of the linear trend supplied
it looks like this:



As you can see, sea level is not accelerating. In fact
there's a little bit of deceleration going on. The other
side doesn't want to talk about that very much.
