In the film, tornadoes whip through Los Angeles and New York is buried by a storm surge of Biblical proportions – all in a matter of days. Could an eco-Armageddon really happen so quickly with these effects?
No. When scientists refer to abrupt changes in the earth's climate, they are generally referring to changes that occur over a 10- to 20-year time horizon, not a week to 10 days. According to the National Research Council, "Greenhouse warming and other human alterations of the earth system may increase the possibility of large, abrupt, and unwelcome regional or global climatic events … Future abrupt changes cannot be predicted with confidence, and climate surprises are to be expected."
The movie depicts a massive freeze sweeping across Europe and then striking the northern half of the United States , forcing a mass migration to Mexico for survival. Is this how global warming will shake down?
No. First of all, the ocean's role in the North Atlantic is very important, but it is not the only influence on Europe ’s climate. In addition, weather systems in the Northeastern U.S. are mostly controlled by Canadian air masses, not the North Atlantic . So it is not clear what impact a disturbance in the North Atlantic would have upon the U.S.

what kind of signs would we be expecting a month before it actually happens.
It bears a very shocking resemblance to what happend when everything froze in Day After tomorrow!
Things in the movie that have happened in the last year:
I didn't think the science in the movie was convincing at all

From what I undestand, climatologists were wary of the movie because it had bad science, and then were really wary of it because people saw the movie and figured that thats what the climatologists were talking about, which was absurd enough that it needn't be heeded.
How realistic is this movie?
It has a kernel of truth, although it has been "Hollywoodized." There is evidence that abrupt climate change has happened a couple of times in the last 13,000 years, but it's never happened in a few days, as it does in the movie. That's completely impossible.
