Ian Plimer is a professor of Mining Geology at the University of Adelaide, South Australia, and Emeritus Professor of Earth Sciences at the University of Melbourne.

Plimer has two climate science denial books. The first, which has been referred to as the “denier's bible,” was Heaven and Earth. The second, published in late 2011, was called How To Get Expelled From School: A guide to climate change for pupils, parents and punters.

Plimer has been a director of numerous mining companies including Ivanhoe Australia, a subsidiary of Bob Friedland's Ivanhoe Mines, CBH Resources, Kefi Minerals, Silver City Minerals, Ormil Energy Ltd, TNT Mines, Niuminco Group and Lakes Oil.

Plimer was appointed to the boards of Roy Hill Holdings and Queensland Coal Investments by mining magnate and climate skeptic promoter Gina Rinehart on January 25, 2012. [3]

As non-executive Director and Deputy Chairman of Kefi, he owns 3.6 million shares which would be worth hundreds of thousands of dollars in today's market. 

In an article titled “Why I'd put global warming on ice,” Plimer claims that his commercial interest in mining “does not colour his arguments, which he says are based on pure science” and “does not affect the independence of his beliefs.” [4]

Stance on Climate Change

According to a presentation by Plimer with the Friends of Science: [5]

”- [The] Earth['s climate] always changes
- Climate change is normal
- Climate change occurred well before humans were on Earth
- The rate of climate change today is no different from thousands, millions or billions of years ago
- >80% [of the] time, Earth has been warmer and wetter than at present
- Ice is rare
- Just because [climate] change occurs in our lifetime does not mean that we humans are driving the change”

Key Quotes

“Climate has always changed. It always has and always will. Sea level has always changed. Ice sheets come and go. Life always changes. Extinctions of life are normal. Planet Earth is dynamic and evolving. Climate changes are cyclical and random. Through the eyes of a geologist, I would be really concerned if there were no change to Earth over time. In the light of large rapid natural climate changes, just how much do humans really change climate?”

“There is no problem with global warming. It stopped in 1998. The last two years of global cooling have erased nearly thirty years of temperature increase.” [6]

Key Deeds

December 12, 2011

Plimer published the “anti-warmist manual,” How to Get Expelled From School: A guide to climate change for pupils, parents and punters, which was reviewed by numerous sources and found to be scientifically inaccurate, containing flawed or undocumented diagrams, and sloppily edited. [7], [8], [9]

The book has been billed as the “anti-warmist manual for the younger reader” [10] and was launched by free-market think tank Institute of Public Affairs. Former Australian Prime Minister John Howard launched the book in Sydney.

The Australian Government responded with “Accurate Answers to Professor Plimer’s 101 Climate Change Science Questions” (PDF), saying the questions posed in Plimer's book are “misleading and are based on inaccurate or selective interpretation of the science.”

The Government report was created to “provide clear and accurate answers to Professor Plimer's questions. The answers are based on up-to-date peer reviewed science, and have been reviewed by a number of Australian climate scientists.” [11]

July 2011

Plimer spoke at a private luncheon hosted by billionnaire mining magnate Gina Rinehart. Crikey reported that in the audience were several high-powered politicians and diplomats, including Western Australian Premier Colin Barnett, the state's environment minister Bill Marmion, former Japanese Prime Minister Yasuo Fukuda and Chinese Ambassador Chen Yuming. Rinehart described Plimer as “one of the leading sources of reasoned and factual information in Australia on global warming and climate change”.

May, 2010

Plimer was a speaker at the Heartland Institute's 2010 International Conference on Climate Change. [12]

DeSmogBlog found that the sponsors for Heartland's 2009 International Conference on Climate Change had collectively received over $47 million from oil companies and right-wing foundations.


Plimer Published Heaven and Earth in 2009. The book asserts that the temperature changes we have observed in the 20th century are within the “normal range of variability,” that significant global warming is not happening and that there is negligible human impact on warming.

His book was received critically, having been debunked numerous times by scientists. [13], [14]

Some critics have even accused Plimer of plagiarism. [15]

In his review of Heaven and Earth for The Australian, astronomer Michael Ashley wrote: [16]

“Plimer probably didn't expect an astronomer to review his book. I couldn't help noticing on page 120 an almost word-for-word reproduction of the abstract from a well-known loony paper…[that] argues that the sun isn't composed of 98 per cent hydrogen and helium, as astronomers have confirmed through a century of observation and theory, but is instead similar in composition to a meteorite.

“It is hard to understate the depth of scientific ignorance that the inclusion of this information demonstrates. It is comparable to a biologist claiming that plants obtain energy from magnetism rather than photosynthesis.”

The Guardian's George Monbiot criticized Plimer's book, saying “Since its publication in Australia it has been ridiculed for a hilarious series of schoolboy errors, and its fudging and manipulation of the data.” Plimer responded by challenging Monbiot to a public debate. [17]

Monbiot then challenged Plimer to give a set of “precise and specific responses” to his critics' points. Plimer rejected this challenge. [18]

Monbiot called Plimer “a grandstander, who wants nothing more than to make as much noise as possible in the hope that it will drown out the precise refutations published by his book's reviewers.” Plimer subsequently reversed his earlier refusal, saying he would answer the questions in return for a live debate. [19]

Instead of answering the questions that Monbiot posed, Plimer responded with his own set of questions. No official debate was actually held. [20]  

The two did debate, however, on ABC's Lateline in December, 2009. Monbiot concluded that Plimer had “used evasion and distraction when faced with straight questions,” and that the overall view was that “Plimer had been soundly thrashed.” [21]

December, 2009

During the United Nations Climate Change Conference 2009 (COP15), Plimer spoke at a rival conference in Copenhagen called the Copenhagen Climate Challenge, which was organized by the climate change skeptic group Committee for a Constructive Tomorrow (CFACT). [22]

Among Plimer's arguments at the conference is how carbon dioxide is “not a pollutant, it is plant food.” See footage of Plimer here. [23]

While the UN's conference attracted 33,200, the skeptics attracted only 60 people. “They’ve got us outnumbered, but we've got them outgunned, and that’s with the truth,” Plimer said at the conclusion.



According to a search of 22,000 academic journals, Plimer has published more than 40 research articles in peer-reviewed journals, mainly on the subject of ore deposits.
