William Kininmonth is a retired meteorologist and headed the Australian Bureau of Meteorology's national climate center for 12 years, although the bureau has pointed out that the center did not actually research climate change during his tenure. He is an adviser to several climate science denial groups.
Kininmonth is the director of an organization called the “Australasian Climate Research Institute.” Kinimonth's “Climate Research Institute” appears to be run out of his home in Australia, as the mailing address for the Institute is the same as Kinimonth's residence.
Stance on Climate Change
“In a spirited defence of his integrity, Tim Flannery (Insight, 8/10) repeats his misunderstanding of how the climate system works: Greenhouse gases emit more radiation than they absorb and their direct impact is to cool the atmosphere. More greenhouse gases will not cause the atmosphere to warm, as Flannery states in his book.” 
“Reducing emissions of CO2, as proposed under the Kyoto Protocol, will not avert climate change.” 
“Fundamental science has always identified that it is quixotic to attempt regulation of climate through management of carbon dioxide emissions. The pity is that community leaders have been beguiled by the mystery of powerful computers and have failed to critically assess the predictions within the context of Earth's history.”

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
Kininmonth was a lead author of the first chapter of a report from the Nongovernmental Panel on Climate Change, a project funded through the Chicago-based Heartland Institute and which concluded that any global warming caused by human emissions of greenhouse gases would cause “no net harm” to human societies.
Kininmonth was a co-author of the book Taxing Air: Facts & Falacies About Climate Change. The two main authors were Bob Carter and cartoonist John Spooner, alongside fellow sceptics Martin Feil, Stewart Franks and Bryan Leyland. The Institute of Public Affairs sent copies of the book to Australian Members of Parliament and hosted a launch event. Australian mathematical physicist Ian Enting, author of the Australian Mathematical Scences Institute book Twisted: The distorted mathematics of greenhouse denial, has analysed the book, describing it as being characterised by “half-truths and slanted misrepresentation” and “appalling hypocrisy”.

A total of sixteen “scientists” are signatories including Claude Allègre, J. Scott Armstrong, Jan Breslow, William Happer, Richard Lindzen, James McGrath, Rodney Nichols, Burt Rutan, Harrison H. Schmitt, Nir Shaviv, Edward David, Michael Kelly, Henk Tennekes, Roger Cohen, and Antonino Zichichi.
Media transparency, who found that the article had misrepresented the position of Yale economist William Nordhaus, also reported on the opinion piece. Skeptical Science did a comprehensive examination of the signatories. , 
In the WSJ op-ed, Kininmonth was described as the “former head of climate research at the Australian Bureau of Meteorology”. The bureau later released a statement clarifying that Kininmonth had been the head of National Climate Center (NCC) from 14 November 1985 to 8 January 1998, but this center was not researching human-caused climate change. Instead, the NCC's activities had “mainly centred on climate database management and climate monitoring activities”, the statement said.

Kininmonth was a speaker (PDF) at the Heartland Institute's annual International Conference on Climate Change (2010).
His speech was titled “Natural Responses Limiting Anthropogenic Climate Forcing.” 
March 8 - 10, 2009
DeSmog investigated sponsors behind the conference and found that they had collectively received over $47 million from oil companies and right-wing foundations.
William Kininmonth, “Science Advisor” to the ACSC, spoke about “Climate Change and how he believes it is just a cycle - based on historical facts.” View the five-part video series, via YouTube, below: 
Kininmonth was on the “writing team” for the Fraser Institute's 2007 independent summary for policymakers (ISPM).
The ISPM's conclusion is that “there will remain an unavoidable element of uncertainty as to the extent that humans are contributing to future climate change, and indeed whether or not such change is a good or bad thing.”

Kininmonth signed an open letter to the UN Secretary-General Ban Ki-Moon that describes global warming as a natural phenomenon.
The letter describes carbon dioxide as a “non-polluting gas that is essential to plant photosynthesis,” and claims that the IPCC's reports are “inadequate as justification” for implementing climate change policy. 
Kininmonth was one of the signatories of a 2006 open letter to Prime Minister Stephen Harper titled “Open Kyoto to Debate” which denied the existence of man-made global warming and encouraged inaction on climate policy.

According to a search of 22,000 academic journals, Kininmonth has not published any research in a peer-reviewed journal on the subject of climate change.
There is one study published in 1972 by “Kininmon, WR” on the subject of rain-grown rice in Northern Australia.
In November 2004, the Lavoisier Group helped launch Kininmonth's book Climate Change; a natural hazard.
