Abstract
Climate change represents an unprecedented threat to animal life on Earth, brought about by a single species: humanity. It is well-known that humans will suffer greatly as a result of continued climate change over the coming decades and centuries, but the calamitous effects on other animals are often downplayed. Here, the origins and potential scope of climate change are explored and the implications for the whole animal kingdom are summarized. It is argued that humans, as part of this kingdom, have both a responsibility and an imperative to take immediate steps to avert climate change for the sake of all animal life.
