It is a scientific fact that the moon gets farther and farther away from the earth each year. And it is also a fact that the moon's orbit has a direct correlation to the tides and weather patterns. I think that the increasing intensity of the weather over the past decade or so is just a taste, the beginning of the end. I think that as the moon continues to drift farther and farther from the Earth, the weather is going to get more and more intense, the tornadoes and earthquakes growing in number and in size, causing more destruction and loss of life (think similar to the movie The Day After Tomorrow). I think that is going to cause changes in the tides and shorelines, but the climate will gradually become uninhabitable by man. There will be some species that will evolve and survive in the "new world" but I don't think the human race will be among them. But again, I think it's going to be a gradual thing as the human population dwindles and ultimately dies out. I don't think there's going to be a specific date when the world will end like some theories out there...
