This is a science fiction novel, not a fantasy novel. Science fiction is something that can happen whereas fantasy cannot. The story is one of the millions of possible scenarios that could originate from where we are today in respect to global warming. This scenario begins at our present time and continues through the year 2202. The best argument against the danger of global warming is that the human race will probably annihilate itself over other issues long before global warming runs its course. This may well be the case, but like most things you can't count on it. It may be prudent for the countries of the world to try to prevent both.
