Scientists are saying that it will not be too long before the polar ice-caps melts and submerge much of the earth's land. Millions and millions of people will be displaced and this will eventually result in a "survival of the fittest syndrom". But do you think that humans are capable to evolve into sea living mammals?

No, because the whole Earth will not be submerged, and humans are far too spread out and interlinked with each other to evolve any further from where they currently are. The only way humans will ever evolve again is by selective breeding / genetic engineering, rather than natural selection.
The stories about most of the Earth's land being submerged are in all likelihood fiction and hysteria. Sure, some people will be displaced, but that's our own fault for building near the coasts (although, back then we weren't to know that the Earth doesn't have a stable climate).
My source is a graph of sea level change over the last 24,000 years. Humans survived that without any problem, we can definitely survive a few meters here and there, if the worst comes to the worst.

No, although some scientists think dolphins may have evolved from land animals in the distant past.
By the way, no scientist says that melting polar ice will submerge much of the earth's land. If ALL polar ice melted it would submerge only a SMALL percentage of the Earth's land.

No. If worse came to worse we'd die off quickly. Evolution takes a very long time and if the ice caps melt, it will most likely be much quicker than a decendant of humans can keep up with.
Evolution is a long process, I guess it's possible if a gilled person gets with another and makes a gilled baby but that's not really abundant at the time. Dolphins are already capable of that so they'd kill us before we got the chance.

Sorry to correct you, but there is no such scientific idea as "survival of the fittest"
Darwin's evolutionary theory stated: Survival of the fitter, which makes a big difference.
I wouldn't call it impossible, but from a theoretical standpoint it doesn't look too likely. I say this because evolution occurs over large periods of time, and if in fact we were to be placed underwater - we would all die before ever being able to evolve. If we were only semi underwater through all of this time, we would have no need to evolve because we could still breath above the water.
Evolutionary theory calls for large periods of time, and motivation. Here, these two do not coexist.

No, I don't think so. Humans can't evolve into anything. They never did and they never will.

no we can vent the ocean into space and get our land back
