Killer tornadoes. Violent tropical storms. Devastating temperatures. Are these just the prelude to an unprecedented environmental disaster in our near future?

Two of America's leading investigators of unexplained phenomena -- Art Bell, the top-rated late-night radio talk-show host, and Whitley Strieber, No. 1 "New York Times" bestselling author of "Communion" and the legendary "Nature's End" -- have made a shocking discovery based on years of research with top scientists and archaeologists from around the world. Now, they reveal what powerful interests are trying to keep hidden: rapid changes in the atmosphere caused by greenhouse gases have set humanity on an incredibly dangerous course toward a catastrophic change in climate in the immediate future. It will begin with a massive, unprecedented storm that will devastate the Northern Hemisphere. This will be followed by floods unlike anything ever seen before -- or perhaps a new Ice Age. They also unearth evidence that this has happened inthe past -- in fact, that it has occurred regularly throughout geologic history, but so infrequently that our only record of the last such storm
