The only problem with this theory is that much worse disasters have happened in the past.
1. Black Plague. Not only did this disease kill of 25% of asia and europe, but it was made worse by terrible weather that ruined some growing seasons. Both disease and famine were commmon. No second coming.
2. Supervolcanoes. The last big supervolcanoe to erupt was Toba. There was a mass extinction associated with event. In fact, the human population was thought to have been shrunk to a few thousand. No natural disaster, with respect to the human population, has ever equalled this event. A smaller supervolcanoe totally destroyed the civilization on the island of Thera. The island just blew up, presumably killing everyone on the island. This would have killed thousands, dwarfing the death toll of other modern day eruptions such as Mt. St. Helens. Don't forget about Pompei either.
3. Tsunamis. This latest tsunami is not that bad compared to other tsunamis that have occured in the time that humans have been on this earth. For instance, a giant landslide caused a mega-tsunami that ravaged stone age civilizations in the northern part of England. This tsunami dwarfs the most recent tsunami in the Indian ocean.
These are but a few examples of worse disasters that have occured in man's lifetime. Recent changes in weather, disease, and natural disasters are not any worse than have occurred in the past. The problem is the memory span of humans. We often forget, even in our own lifetimes, how things were in the past. For instance, current winters always feel much colder than previous winters, even if the current season is warmer than those in the past. Diseases have killed off many more people in the past. Natural disasters have been far more severe and far reaching in the past than they are now. It is just human nature to overemphasize the present and tone down past events.
