AN Adelaide professor says climate change is unavoidable - but that humans are not the cause of it.
University of Adelaide Professor of Mining Geology Ian Plimer this week launches his seventh book, Heaven and Earth, Global Warming: The Missing Science, which aims to refute every scientific argument that humans are responsible for global warming.
Professor Plimer embarked on the project after being incensed by increasing public acceptance of the idea that humans have caused global warming.

Many scientists worldwide agree that high levels of carbon dioxide in the atmosphere have caused global temperatures to rise.
Professor Plimer said his book would "knock out every single argument we hear about climate change", to prove that global warming is a cycle of the Earth.
"It's got nothing to do with the atmosphere, it's about what happens in the galaxy.
"You've got to look at the whole solar system and, most importantly, we look back in time.
"There's a lot of talk out there that there isn't any science that supports my view, but I have 2111 scientific references in this book."
Professor Plimer has been awarded two Eureka prizes, for science promotion and best science book, and a Centenary Medal for his geological contribution to Australian society.
He said the planet has endured constant climate change and rapid changes had occurred in the past.
"Not one has been driven by carbon dioxide," he said.
The book outlines how climate is driven by the sun, the Earth's orbit and plate tectonics.
It will be released in Britain and U.S. after its Australian launch.
