About this book
Sixty-six million years ago, an asteroid as large as Mt. Everest hit what is now the Yucatán 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 starvation due to agricultural failure, while 6 billion people might starve following a war involving Russia, NATO, and the U.S.
The book describes how the dinosaurs died, and how their deaths parallel what might happen to people after a nuclear war. The book reflects on the odds of future asteroid impacts, how to stop them, and ends with what the readers personally and together can do to prevent a nuclear war, so that humans don't end up like the dinosaurs.

Biography
Owen Brian Toon is a Professor in the Department of Atmospheric and Oceanic Sciences and the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder. He is a Fellow of the American Meteorological Society, the American Geophysical Union and the American Association for the Advancement of Science, and winner of AGU's Roger Revelle Medal and AMS's Carl-Gustaf Rossby Research Medal. He was recognised by the United Nations Environmental Program for contributing to the U.N.'s 2007 Nobel Peace Prize for Climate Studies, and co-won the Future of Life Institute Award in 2022 for the discovery of Nuclear Winter.
Alan Robock is a Distinguished Professor of climate science in the Department of Environmental Sciences at Rutgers University. He graduated from the University of Wisconsin, Madison, in 1970 with a B.A. in Meteorology, and from the Massachusetts Institute of Technology with an S.M. in 1974 and Ph.D. in 1977, both in Meteorology. Before graduate school, he served as a Peace Corps Volunteer in the Philippines. He was a professor at the University of Maryland, 1977-1997, and the State Climatologist of Maryland, 1991-1997, before coming to Rutgers in 1998. Prof. Robock was a Lead Author of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change.
