Europe and the USA will soon be covered by thick ice, according to the scientific report section of "Dark Visitor." The primary author is a Harvard educated astronomer and one of the other two has a Ph.D. in climatology and worked for NOAA, so this report must be taken seriously. Recent astronomical observations indicate that a black hole is approaching our solar system. Although the black hole will pass more distant than the orbit of Saturn, its gravity will slightly change the Earth's orbit. The year will become 378 days long. During winter it will be 6% closer to the sun and during summer, 11% farther away. The resulting milder winter and cooler summers are a curse, not a blessing. Heavy "spring snows" will fall all winter long and not entirely melt in the colder following summer. Mathematical proofs of these facts are included in the scientific report section and appendix.
The approaching black hole will never be visible in telescopes, but its trajectory is now known from observations of small perturbations in Pluto's orbit. If the authors' predictions are true, the global catastrophe that will begin in 2007 will be far worse than any that has ever occurred before.
