Extinction
Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on...

Contact with Alien Civilizations
This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.
From Meteorite Impact to Constellation City
From Meteorite Impact to Constellation City is a historical geography of the City of Greater Sudbury. The story that began billions of years ago encompasses dramatic physical and human events. Among them are volcanic eruptions, two meteorite impacts, the ebb and flow of continental glaciers, Aboriginal occupancy, exploration and mapping by Europeans, exploitation by fur traders and Canadian lumbermen and American entrepreneurs, the rise of global mining giants, unionism, pollution and re-greening, and the creation of a unique constellation city of 160,000.
