Earth in Flames : How an Asteroid Killed the Dinosaurs and How We Can Avoid a Similar Fate From Nuclear Winter

Sixty-six million years ago an asteroid as large as Mt.Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet.Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires.This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.The major culprits in these extinctions are loss of sunlight due to absorption by the smoke and decade-long ice age temperatures.A nuclear war with just a few hundred of the world's 12,000 nuclear weapons targeted on densely populated cities could plunge Earth into the same types of conditions that the dinosaurs experienced.Even a war between India and Pakistan could kill 1 to 3 billion people from st
