Let me explain what I mean by terraforming. Let's say we want Antarctica to be like Scandinavia or Finland. People from all over the Earth would colonize it and build the "United States of Antarctica" or something similar. It would basically become a next-generation USA.
I know that a lot of ice will melt on the continent, and the ocean level will increase. This can be a serious problem for the rest of the planet, but let's say we (or aliens, for example) have the technology to "suck" this water and use it for some industrial purposes (that's irrelevant). I know, however, that changes in temperature may lead to some serious problems in our world. It may disrupt the temperatures around other places, et cetera.
Now for the question:
Is it possible to change Antarctica to resemble Northern Europe (temperature) without harming the rest of the globe?
The best answer will contain:
Is it possible at all to "terraform" the frozen continent (see what I mean by terraforming)
how can we not harm our planet by doing so
HOW would that be possible? Exotic technologies of the far future:enabled !
