I believe that with current technoloies and systems aimed at spotting things that may collide with earth we would have plenty of time not only to watch weather guy/girl announce it, but also make some debates, polls, protests and many others things pror to impact

yep and no matter what they say were still going to get pummeled by a rock. humanity had no chance

Actually, I think that whether or not humanity would have a chance, would depend on a couple of things: mainly, how long before the impact you detect the comet, how large it is, and its composition. If you have years of advance notice, you can try to tug it out of harm's way (https://en.wikipedia.org/wiki/Gravity_tractor) - that would be the best bet at the moment, I guess. Less than that, you could try more direct approaches (destroy, deflect, etc.), but chances might be good that we would still get it, if not by the comet itself, by the debris.
