We admit that our critical examination of rapid-climate change disaster flick The Day After Tomorrow contained a fair measure of glittery Hollywood flair. But it doesn't take a paleoclimatologist to realize that abrupt climate change can't really happen in a week, and our writer Matthew Teague didn't actually climb a mountain of skulls in Africa to find that out. Even though we indulged in a measure of dramatic exaggeration, the original source material shocks the reader with plausible conjecture. Peruse the cruel truth in the Pentagon report--authored by the Oracle of the Future (a.k.a. futurist Peter Schwartz)--which outlines the global impact, such as sudden food and water shortages, that rapid climate change could provoke.
