Plimer has two books questioning the existance of man-made climate change including Heaven and Earth, and a second titled How To Get Expelled From School: A guide to climate change for pupils, parents and punters, descibed by some as the “anti-Warmist manual for the younger reader.” 
Energy & Mining Industry Connections
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.
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.” 
Stance on Climate Change
“What is now regarded as human-induced climate change, any scientist will say well that's just normal variability. Climate varies, temperatures vary, sea levels go up and down like a yo yo.”
”- [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”
“There is no problem with global warming. It stopped in 1998. The last two years of global cooling have erased nearly 30 years of temperature increase.” 
The following are some notable quotes from Ian Plimer's interview with Steve Johnson on BBS Radio:
“Greens don't read book. That's evident from their perpetual ignorance.” 
“To be a green is to be anti-environmental.” 
“Just give a green a sniff of a few dollars and they change very quickly.” 
“The Green Movement is in effect attacking western civilization.” 
“If we look back in just the last 10,000 years, we're living in quite cool times. For people that claim we've had the hottest year ever, it's just absolute codswallop. We have had about 8,000 years where it's been much hotter than now.” 
“Temperature hasn't really changed for about 20 years. Yet the models are saying the temperature […] is going to increase extraordinarily. So what has been done, is the primary data has been changed to fit the model. That is fraud.” 
“The weather always changes. And weather over 30 years, you then start to call climate. Just because you've got one hot year doesn't mean you have climate change. The weather always changes. If you move from say Helsinki to Florida, then you have a temperature change of about 30 degrees Celsius upwards. You do not die from that temperature change.” 
“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.”

Plimer was a guest on Andrew Bolt's Bolt Report where he discussed the release of his new book to be launched on October 5 titled The Climate Change Delusion and the Great Electricity Ripoff. During his interview, Plimer asserts that climate models have been “doctored” and promote a “fallacy based on fraud promoted by fools.” 
“To think we can do something is the ultimate of narcissism,” Plimer said. “And it's all based on a failed fundamental: The fundamental is that it is the human emissions of carbon dioxide that drive global warming. That has never been shown. 99% of emissions are natural. “
[…] the 2nd thing is that we have to cur our emissions. Cut this plant food that we're putting into the atmosphere. Now, to cut that, we build wind industrial complexes and solar complexes. Now, the amount of toxins that we release, the amount of carbon dioxide to build them, and to maintain them, to transport the products, doesn't save anything.”

Ian Plimer was listed as a contributor to Climate Change: The Facts 2017, a book released by the Institute for Public Affairs (IPA) and edited by Jennifer Marohasy. While investigating the authors, DeSmog noted that one of the IPA's listed “leading experts” involved in the book is New Zealand’s Ken Ring, who in addition to being a described “long range weather forecaster” has written “two, possibly three, books about cats” including Pawmistry: How to Read Your Cat’s Paws in 1998. , 
“[O]ur understanding of how the climate operates is incomplete and it is critically important to challenge the view that the planet is facing a global warming catastrophe.”
“Climate Change: The Facts 2017 brings together contributions on the latest climate science from some of the world’s leading experts in the field including John Abbot, Sallie Baliunas, Paul Driessen, Tony Heller, Craig Idso, Clive James, Pat Michaels, Jo Nova, Ian Plimer, Tom Quirk, Peter Ridd, Ken Ring, Nicola Scafetta, Willie Soon, Roy Spencer, and Anthony Watts.
Before posing this question, Plimer claims that “it has yet to be shown that human emissions of CO2 drive global warming.” He adds that “Australia has far greater economic priorities than to change a whole economy, increase energy costs, decrease employment and decrease international competiveness because of one poor lonely molecule of plant food in 6.6 million other atmospheric molecules. 
The argument, that CO2 is just a trace gas compared to others in the atmosphere, is a common “climate myth” that has been debunked at Skeptical Science. While CO2 may be a small percentage of the atmosphere, that doesn't change the large effects it can have on climate. Plimer also touts the “greening” of CO2 (debunked here):
“Satellite measurements show that there has been a greening of the planet over the last few decades, thanks to a slight increase in traces of plant food in the atmosphere.” Plimer adds that, “Without CO2, there would be no plants and without plants, there would be no animals.” 
He also claims that it hasn't warmed in two decades: (further debunked)
“The planet has not warmed for two decades despite a massive increase in CO2 emissions during the industrialisation of Asia. “ 
Ian Plimer is listed as a “Founding Member” of group named Climate Exit (Clexit) led by climate change denier Christopher Monckton. According to Clexit's founding statement (PDF), “The world must abandon this suicidal Global Warming crusade. Man does not and cannot control the climate.” , 
Desmog reports on how the group grew in the wake of the UK's decision to leave the EU. A key member of Clexit's “60 well-informed science, business and economic leaders” is Hugh Morgan, a former board member of the Reserve Bank of Australia and former CEO of Western Mining Corporation with close ties to Australia's Liberal party. , 
According to Clexit's founding statement:
“If the Paris climate accord is ratified, or enforced locally by compliant governments, it will strangle the leading economies of the world with pointless carbon taxes and costly climate and energy policies, all with no sound basis in evidence or science […]” 
August 29, 2016
Ian Plimer spoke at the Far Northern branch of the Australasian Institute of Mining and Metallurgy (AusIMM). Cairn Post writes that AusIMM Far Northern branch chairman Brett Duck described Prof Plimer as Australia’s best-known geologist. 
Plimer was brought in to discuss the Great Barrier Reef. Brett Duck downplayed the impact of climate change: 
“There’s been that many climate changes in the past, and it’s survived in the past,” Duck said. “The reefs will come and go. The sea level will rise and the sea level will fall.” 
January 26, 2016
Ian Plimer went on BBS Radio with Steve Johnson to discuss his two new books, Not for Greens (2014) and Heaven and Hell.
Plimer spends much of the earlier interview criticizing the green movement. According to Plimer, “To be a green is to be anti-environmental.” He also contends that “The Green Movement is in effect attacking western civilization,” and that they are easily corrupted by money. Video below. 
Ian Plimer is a contributor to the book Climate Change: The Facts published by the Institute of Public Affairs and featuring “22 essays on the science, politics and economics of the climate change debate.” The Institute of Public Affairs, while not revealing most of its funders, is known to have received funding from mining magnate Gina Rinehart and at least one major tobacco company. 
The book includes essays and articles from a range of climate change skeptics, with contributors including the following:
- Alan Moran
- Andrew Bolt
- Anthony Watts
- Bernard Lewin
- Christopher Essex
- Donna Laframboise
- Garth W. Paltridge
- Ian Plimer
- J. Scott Armstrong
- James Delingpole
- Jennifer Marohasy

- Kesten Green
- Mark Steyn
- Nigel Lawson
- Patrick J. Michaels
- Richard S. Lindzen
- Robert M. Carter
- Ross McKitrick
- Rupert Darwall
- Stewart Franks
- Willie Soon
According to Editor Alan Moran in a post at Catallaxy Files blog on Climate Change: the facts 2014, Ian Plimer “examines the politics behind the pseudo-science. He notes that many Western governments have a politically popular ideology involving human emission increases in carbon dioxide (CO2) bringing warming, possible catastrophic ‘tipping points’ and a need to phase out fossil fuels as the only means of stopping this. He dismisses the possibility of the catastrophic consequences, drawing from geological history and points to the adverse economic outcomes of attempts to drastically reduce fossil fuel based energy usage.”

Ian Plimer published, “Not For Greens: He who sups with the Devil should have a long spoon,” through Connor Court Publishing. A summary on the publisher's website, describes the book as follows:
“The processes required to make a humble stainless steel teaspoon are remarkably complicated and every stage involves risk, coal, energy, capital, international trade and finance. Stainless steel cutlery has taken thousands of years of experimentation and knowledge to evolve and the end result is that we can eat without killing ourselves with bacteria. We are in the best times to have ever lived on planet Earth and the future will only be better. All this we take for granted.
Greens may have started as genuine environmentalists. Much of the green movement has now morphed into an unelected extremist political pressure group accountable to no one. Greens create problems, many of which are concocted, and provide no solutions because of a lack of basic knowledge. This book examines green policies in the light of established knowledge and shows that they are unrealistic.
Policies by greens adopted by supine governments have resulted in rising costs, increased taxes, political instability, energy poverty, decreased longevity and environmental degradation and they don’t achieve their ideological aims. Wind, solar and biomass energy emit more carbon dioxide than they save and reduction of carbon dioxide emissions does nothing to change climate and only empties the pocket. No stainless steel teaspoon could be made using green “alternative energy”.
This book argues that unless the greens live sustainably in caves in the forest and use no trappings of the modern world, then they should be regarded as hypocrites and treated with the disdain they deserve.” 
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. , , 
The book has been billed as the “anti-warmist manual for the younger reader” 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.” 
Crikey notes that the government subsequently deleted the online version of their document. “We knew it would happen eventually,” they write. 
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.” 
Ian 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.” 
Plimer was a speaker at the Heartland Institute's 2010 International Conference on Climate Change. 
February 1, 2009
Ian Plimer accompanied Lord Christopher Monckton who spoke at a luncheon lecture titled “Apocalypse? NO! ‘Global Warming’ is not a Global Crisis” co-hosted by the Australian Climate Science Coalition and the Institute for Private Enterprise. 
Ian Plimer Published Heaven and Earth. 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.
“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. 
Monbiot then challenged Plimer to give a set of “precise and specific responses” to his critics' points. Plimer rejected this challenge. 
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. 
Instead of answering the questions that Monbiot posed, Plimer responded with his own set of questions. No official debate was actually held. 
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.” 
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). 
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.
