Requiem for a Species: Why We Resist the Truth about Climate Change is a 2010 non-fiction book by Australian academic Clive Hamilton which explores climate change denial and its implications. It argues that climate change will bring about large-scale, harmful consequences for habitability for life on Earth including humans, which it is too late to prevent. Hamilton explores why politicians, corporations and the public deny or refuse to act on this reality. He invokes a variety of explanations, including wishful thinking, ideology, consumer culture and active lobbying by the fossil fuel industry. The book builds on the author's fifteen-year prior history of writing about these subjects, with previous books including Growth Fetish and Scorcher: The Dirty Politics of Climate Change.
