Although animals have evolved over geologic time to Earth's constantly changing environments and the extinctions of certain species are normal, in no other time in the planet's history has the extinction rate climbed as high as it is today. Causes of this include destruction of wildlife habitat, pollution, overfishing, and poaching. Animals illustrates these urgent issues.

Earth has always exhibited patterns of heating up and cooling down. This title focuses on the mechanisms that caused past climate changes, putting the Earth repeatedly into and out of ice ages. It compares natural cycles with today's rapid global warming, caused principally by the behavior of humans.

Climate scientists have repeatedly told us that the 1990s had the warmest temperatures ever recorded since records were consistently kept in the mid-1800s. This title presents an overview of significant climatic periods of the Earth's past and introduces the concept of climate proxies, or natural indicators that can be used to infer past climate.
