I don't think we now have the capacity to kill each other completely anymore. A few hundred thousand could survive a nuclear war, and no it would probably be nothing like Fallout because we really underestimate plant and animal life's capacity to adapt.
If it came down to it and we knew for sure bad stuff was going down with global warning to the point where it posed an immediate and imminent threat (solid evidence that changes would take place within the current generation's life time; which we don't yet have.) I am absolutely sure we could muster up some type of adaptation to it. If it came down to it I think give us 50 years and we could make a viable push to space. We already know how to grow food and completely recycle water. I say 50 years because the growing food part is still in it's infancy (soil-less plant growing) and our current technologies accommodate a small crew, and are not made for extended stays of large populations. Perhaps a more viable method though, is underground. And we don't really need ALL that many people to restore our population.
You're right, re: the urgency of technology. Scientists have discussed it before - they're disappointed that space funding is cut because there is no problem right NOW with the earth, but there is every chance that something COULD happen.
To support your argument re: 50 years, the greatest advances in technology in human history have strangely been during World War 1 and World War 2.. the helicopter (I think) came out of Vietnam.
