A fair comment, but the point of the example was to show that so long as the polar regions remain cold, there is no reason to suggest this will decrease the amount of ice built up.
The earth does have an external cooling device. We radiate heat out into space constantly. If we didnt, our temperature would be increasing dramatically.
You do realize that just a little bit of the polar ice caps are technically on "dry land", right
Yes, hence my comment about the ice on the Antarctic continent itself. Various models have been performed, and the results are by no means clear. Some suggest that ice will melt also, but it is my understanding that most do not. The increased atmospheric moisture seems to increase the rate of ice build up over the antarctic land. There is the *possibility* of the earth over compensating for global warming, what with more clouds reflecting more sunshine. These are the poorly understood areas of climate modelling, to which nobody has an answer.
When the polar ice caps melt, the ocean level does not rise. Why? because as ice they displace the same amount of space as they would if they were water. It is achimedes' principle. It is what keeps ships afloat, what makes submarines work. Consequently, melt ALL the polar ice caps and our friends in The Netherlands wont notice a thing.
This came from a piece of mistaken research earlier last century by the EPA, where they forgot this. It was an honest mistake, since owned up to, but that has not stopped it entering the public mind, and assorted do-gooders still using it for shock value.
One thing that can get us is if the ice on the Antarctic continent melts. This is possible, but highly unlikely. Ever opened your freezer on a hot day? Do you get more or less ice? That is probably not a concern.
So what are the possible problems? is the ocean level rising? Yes, it is. It rises naturally over time due to sedimentation processes, about 20cm/century, IIRC. The thermal expansion of water due to global warming (supposedly, see the ATOC project for more info) is likely to add a similar amount.
One hopes to disillusion one more person every day....
How long till they have an audio and a video tab? One that you can hum a little tune into? or that you can describe a scene and it gives you an mpeg snippet?
One of the best features we found during an evaluation of IDEs at work was the ability to browse a CVS repository, a la SourceSafe. For those of us who are used to this model of source control, this made a huge difference.
We found there were a number of foibles with the CVS integration, but nothing terminal. The thing that really ratted it for us was (or have they fixed this?)
No SourceSafe integration
The editor just... wasnt that nice. Too many keyboard shortcuts that we're used to, things like ctrl-backspace, didnt work.
The code completion is nothing compared to the smart code completion offered in IntelliJ IDEA.
We couldnt work out how to make multiple run configurations, Unit tests be here, Main class(es) be here..
We really felt like in a version or so, it would be a very usable and competitive IDE, but for our purposes (Web application development with SourceSafe source control), didnt seem to quite be there yet.
You're falling into an extremely common trap: 80% of the users use only 20% of the features, therefore you only need to implement 20% of the features and you can take 80% of the market. It doesnt work like that! everyone uses a different 20%, and you also restrict yourself from ever using any of the new features.
You still have to implement all the features of competing systems to be successful.

IIRC, the terminal velocity of a rocket is (to a first approximation) the product of the logarithm of the ratios of the total mass (including fuel) and the payload mass, and the exhaust velocity. This means you nead TONS of fuel to boost a small payload, especially given Earth's escape velocity of 11 km/sec.
The advantage here would be that you dont need to burn fuel to make the fuel move. You dont need to add extra weight to get started. Im not an expert, but i assume that the basic idea would be gather speed (not even necessarily vertically to begin with), and then launch it vertically. It needs to be vertical to escape the drag of the atmosphere as quickly as possible.

As was evidenced by my interaction with vast amounts of rain half way up a local volcano last weekend. Erk. :-)

oohhh baby.
Gee, you'd think this would be all common knowledge, after all, it isnt exactly rocket science (oh wait....)

Wellington (captial of NZ, for our American readers) changed its name to Middle-Earth during the launch of FOTR.
