Becoming Dinosaurs offers a focused analysis of climate change in the context of numerous catastrophic changes the Earth has undergone. The author is a paleontologist who has taken on the task of separating the claims of climate change deniers and hysterical doomsayers to arrive at a rational set of conclusions about how humans might mitigate the effects of inevitable global warming.

The author cites long-term data to demonstrate that we are, apart from human activity, in a warming period. Industry and agriculture, he asserts, have the potential to accelerate warming to a disastrously rapid rate. Trexler notes that people will probably adapt to a gradually changing climate and will most likely deal with increasingly extreme weather, some ocean acidification, and a steady, slow rise in sea level. However, if these events are hastened by unnaturally rapid temperature increases worldwide, a prospect that Trexler finds avoidable but disturbingly likely, it will be "game over" for humanity. The culprit will be the release of methane ice, or clathrates, now trapped beneath ice and cold ocean water. If methane clathrate deposits were to warm to the point that they turn to gas and enter the atmosphere, temperatures around the world would rise so quickly that many life forms would die in a scenario similar to the mass extinctions at the end of the Permian period.

Trexler explains that the current view of the Cretaceous-Tertiary (K-T) extinction, caused by the well-documented impact occurrence 65 million years ago, has been misrepresented as the key event in the extinction of dinosaurs. …
