I just want to applaud your patience (after reading the responses to one of your other posts). :-) I've decided to start throwing questions back on people; seeing as the legitimate science is on the side of climate change, let those who disbelieve Show me the facts!! (to paraphrase Cuba Gooding Jr.)
All the best...Brian

Thanks, Brian! Patience is an effective tactic, though I have been known to lose it ;)

A question to ask is how much of the sea level rise in the other parts of the world is due to declining sea levels in the Arctic?
Secondly, how much variance between sea levels around the world is normal? Or possible?

That is an interesting question. I think local sea levels can vary as much as a metre from the average. The wiki article on sea level is very interesting.
http://en.wikipedia.org/wiki/Sea_level
Actually it says "The location-dependent, but persistent in time, separation between mean sea level and the geoid is referred to as (stationary) sea surface topography. It varies globally in a range of +/- 2 m."

Sea levels are not more than persistent, as is 'Climate' in observed 'overall' behavior.
There is nothing to be made for 'unnatural' climate change by watching 'relative sea levels', especially in humanistic time frames.

So what is the big mystery about the Arctic ocean level falling ?
Since that is exactly what is predicted by the laws of physics (high school physics even); I don't see why all these high falutin climatologists can't figure it out.
Look in "Physics Today" for January 2005 Letters section; where it was predicted that that is exactly what is supposed to happen when floating sea ice melts.
If you ever got out of a hot shower and felt chilly; then you already know why the arctic ocean level is supposed to fall when the floating sea ice melts.

Hi George,
I am confident you meant this letter, which appears to be your own?
The laws of physics are truly beautiful, universal and simple. However, the way they interact with each other in the real world can often be messy, surprising and complicated. It is a grave error to extrapolate from a simple thought experiment about an ice cube melting in a glass to a prediction of the behaviour of a vast and interconnected system like the arctic ocean.
Having read your letter, all I can suggest is that you try to become a little more familar with all the fine work that climate scientists have accomplished over the decades before assuming that a little physics and some common sense can so easily do so much better.
In particular, you could start with my articles on how we know that the CO2 rise is anthropogenic and why the GHG/temperature record in the Vostok ice cores does not imply that CO2 doesn't drive temperature.
Did you follow up on the references Spencer Weart provided?

Notice how the Global Warmists (neo-coms) don't believe anything unless it is peer-reviewed by another neo-com.

Okay... So I'm going to cherry pick... does this in any way what-so-ever support the Expanding Earth theory...
I am not a geologist or physics guy... I am just curious...

Knowing nothing about the Expanding Earth theory beyond what it's name suggests, I am not sure what one would expect in terms of sea level.
Some questions that arise: against what are the satelitte measurments calibrated? Distance form the center of the earth? (that seems the most likely). In an expanding earth situation sea levels would lower because of spreading out as well as rise as the crust rises, but what is the net effect?
