Actually climate models are *not* 'teh suck'. They have problems just like any other piece of incredibly complex software, but they allow us to learn about things that we otherwise could not study. As for hurricanes, that comment shows a general lack of understanding of climate, weather, and climate models. There is scientific consensus that there is no (know yet) link between climate change and hurricane FREQUENCY. Due to the scientific method being what it is, this may change. That does not mean we are now wrong or teh suck, merely that the scientific method works. There is a known link between hurricane STRENGTH and LONGEVITY and ocean temperatures.
The climate model I work with (EdGCM) doesn't have a dynamic ocean, but that is because it needs to be simple enough so you can download it and run it on your laptop. It does have a 9 layer atmosphere and is in general agreement with the ensemble runs of most of the other GCMs out there.
The EdGCM project has wrapped a NASA global climate model (GCM) in a GUI (OS X and Win). You can add CO2 or turn the sun down by a few percent all with a checkbox and a slider. Supercomputers and advanced FORTRAN programmers are no longer necessary to run your own GCM.
If you want to geek out and track the lifespan of the various Mars missions, you can do so on your Palm with MarsClock. If you want the desktop version check out Mars24. Both should be updated for Pheonix sometime this year.
ENSO is the El Nino Southern Oscillation. If you'd like to simulate global warming and El Nino / La Nina cycles yourself you can do some of the experiments discussed in the article.

False. Ocean water and sea ice have different densities and salinity, and therefore melting sea ice *does* contribute (a very small amount) to the sea level. For an in-depth discussion of this check out the EdGCM forums here: http://forums.edgcm.columbia.edu/showthread.php?p= 954#post954

Unfortunately the ice sheets are not fully dynamic in this model for land ice, but you can see ocean ice retreat significantly.

There are plenty of GCMs that run on Linux, but none that I know of have a GUI interface. We have it on our ToDo list, but I expect it'll take a few years at a minimum to get the Linux port, because it'll require a complete rewrite of the interface.

If you'd like to track the (global) location and the time of the Mars rovers, or the time for any location on Mars, you can do so on your Palm Pilot with MarsClock, written 100% (coded, compiled, debuged) on my Palm with OnBoardC.
The storms are *way* more than this. The last big storm (2000?) had 1 to 10 per second = thousands per hour. The numbers listed here might be more than a normal leonid, but are less than a peak storm event.
Has any GCM ever been validated in your definition? If so, then yes, this one has too. If it is an impossible task to validate a GCM, then your trick question got me, and no, this one is not.
If you'd like to run a global climate model (GCM) yourself, you can now do so. The NASA GISS Model II GCM has been ported to run on Mac/Win computers and wrapped in a point-and-click interface. GISS, the Goddard Institute of Space Studies, is the lab that Hansen (mentioned in the summary) runs.
The EdGCM project provides this free GCM wrapped in a GUI. If you want to add CO2 or turn down the sun or whatever, you may now do so with some checkboxes and sliders.

You can use the values for paleo-climate to get CO2, N2O, and other greenhouse gasses from pre-industrial and pre-human times. You can set up trends (changes in inputs) for the future. You can take modern values and then at the year 2010 have everything drop to pre-human values. Run the model for a few hundred years (a day or two on a modern computer), and you'll see how long until the Earth reaches equilibrium.
It is for Win 2K, XP, and OS X 10.3+. I'm not sure what HT means. Yes, I think it would run on your hardware if you have the right OS, but not extremely fast. CPU is much more important that RAM for the GCM.
Turning the sun down was just 1 example. You can do a huge number of experiments, paleo-climate to modern or future, trends for all the greenhouse gasses, orbital variation, etc.
We don't have animals in our climate model, but if you'd like to see how orbit effects climate, you can do so yourself.

Humans do the same thing. The term is "microsleep", lasting from 2 to 30 seconds or so, often with eyes open. A quick search returns hundreds of PDFs on the phenomenon.

Yes, sea ice reduction is a positive feedback, meaning it will probably accelerate. To what extent? I'm not sure of the magnitude of the acceleration, as there are a lot of other feedbacks going on at the same time.

This is great. According to the Gore film An Inconvienent Truth the auto makers were suing California over emission standards. Counter-suing for once seems like a good idea.

Yes, sea ice reduction is a positive feedback, meaning it will probably
accelerate. To what extent? I'm not sure of the magnitude of the acceleration,
as there are a lot of other feedbacks going on at the same time.
