David John Karoly FAA (born 1955) is an Australian atmospheric scientist, currently based at CSIRO.
In the early 1970s David Karoly enrolled in applied mathematics at Monash University, Melbourne, but later became interested in meteorology. [1] In 1980 he was awarded a doctorate in meteorology from the University of Reading in Reading, England. [2]
After returning to Australia, from 1995 to 2000 Karoly became Director of the Cooperative Research Centre for Southern Hemisphere Meteorology at Monash University. Between 2003 and 2007 he was Professor of Meteorology in the School of Meteorology at the University of Oklahoma (OU). [3] In May 2007 he joined the School of Earth Sciences at the University of Melbourne as a Federation Professor. [1] In 2017 he became Leader of the Earth Systems and Climate Change Hub in the Australian Government's National Environmental Science Program.
He is an expert in climate change, stratospheric ozone depletion, and climate variations due to the El Niño-Southern Oscillation (ENSO). [4]
Karoly has served as a lead author for the Intergovernmental Panel on Climate Change (IPCC) Working Group 2 (on societal impacts) and he is a member of the faculty of the School of Earth Sciences at the University of Melbourne. His work, along with that of the many other lead authors and review editors, contributed to the award of the 2007 Nobel Peace Prize, which was won jointly by the IPCC and Al Gore. [3] He is member of the board of the Climate Change Authority. [5]
In the Australian scene, Karoly is credited with standing up to Alan Jones, a conservative and climate change denying Sydney radio commentator with the largest daily audience in that city of ca.150,000.[ citation needed ]
In doing so Karoly, originally a sceptic (1980), has earned the reputation of being a climate scientist communicator with the ability to explain the complexities of his research to the general public. On The Australian Broadcasting Corporation’s high ranking television program QndA wherein audience members can ask direct questions of experts, Karoly claimed his authority by stating in regard to his nemesis, “I am a climate scientist and Alan Jones is wrong.” [6] [7]
Karoly pointed out that one hundred years ago carbon dioxide in the atmosphere was 280 parts per million whereas now it is 400 parts per million, an increase of 40% which he asserted was unquestionably caused by human activity. He also admonished Australians for producing 1.5% of the world's greenhouse gases when they were only 0.3% of the world's population. On the population issue Karoly sounded a warning, saying, "climate scientists in Europe have said that the long-term sustainable population of people on the Earth is about 1 billion people in 2100 – not the foreshadowed United Nations population estimates of about 10 to 12 billion people. That’s not good news." [8]
The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view, though a few organizations with members in extractive industries hold non-committal positions, and some have tried to persuade the public that climate change is not happening, or if the climate is changing it is not because of human influence, attempting to sow doubt in the scientific consensus.
John William Zillman AO is an Australian meteorologist, and former President of the World Meteorological Organization and the Australian Academy of Technological Sciences and Engineering (ATSE). He was born and was educated in Brisbane, Queensland. Through his leadership in professional organizations and advisory groups, Zillman has contributed to shaping science and innovation policy in Australia. More widely, he has contributed to raising awareness to the consequences of global climate change through involvement in the Intergovernmental Panel on Climate Change (IPCC).
Dennis Geoffrey Jensen is a former Australian politician. He was elected to the House of Representatives at the 2004 federal election, winning the Division of Tangney for the Liberal Party. Jensen lost Liberal preselection for the 2016 federal election, and subsequently resigned from the party to stand as an independent. In August 2017 he joined the fledgling Australian Conservatives party. Jensen has a PhD in materials science from Monash University, and before entering politics worked as a CSIRO researcher. He is known for questioning the anthropogenic causation of climate change.
Alan Belford Jones AO is an Australian former radio broadcaster. He is a former coach of the Australia national rugby union team and rugby league coach and administrator. He has worked as a school teacher, a speech writer in the office of the Prime Minister Malcolm Fraser, and in musical theatre. He has a Bachelor of Arts from the University of Queensland, and completed a one-year teaching diploma at Worcester College, Oxford. He has received civil and industry awards.

Robert Merlin "Bob" Carter was an English palaeontologist, stratigrapher and marine geologist. He was professor and head of the School of Earth Sciences at James Cook University in Australia from 1981 to 1998, and was prominent in promoting climate change denial.
The Great Global Warming Swindle is a 2007 British polemical documentary film directed by Martin Durkin. The film denies the scientific consensus about the reality and causes of climate change, justifying this by suggesting that climatology is influenced by funding and political factors. The program was formally criticised by Ofcom, the UK broadcasting regulatory agency, which ruled the film failed to uphold due impartiality and upheld complaints of misrepresentation made by David King, who appeared in the film.
Alan Simon Finkel is an Australian neuroscientist, inventor, researcher, entrepreneur, educator, policy advisor, and philanthropist. He was Australia’s Chief Scientist from 2016 to 2020. Prior to his appointment, his career included Chancellor of Monash University, President of the Australian Academy of Technology and Engineering (ATSE), and CEO and founder of Axon Instruments, and CTO for the electric car start-up Better Place Australia.

Tom Michael Lampe Wigley is a climate scientist at the University of Adelaide. He is also affiliated with the University Corporation for Atmospheric Research (UCAR). He was named a fellow of the American Association for the Advancement of Science (AAAS) for his major contributions to climate and carbon cycle modeling and to climate data analysis, and because he is "one of the world's foremost experts on climate change and one of the most highly cited scientists in the discipline." His h-index is 107, one of the highest in the discipline. He contributed to many of the reports published by the Intergovernmental Panel on Climate Change.
Heaven and Earth: Global Warming – The Missing Science is a popular science book published in 2009 and written by Australian geologist, professor of mining geology at Adelaide University, and mining company director Ian Plimer. It disputes the scientific consensus on climate change, including the view that global warming is "very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations" and asserts that the debate is being driven by what the author regards as irrational and unscientific elements.
The Climatic Research Unit email controversy began in November 2009 with the hacking of a server at the Climatic Research Unit (CRU) at the University of East Anglia (UEA) by an external attacker, copying thousands of emails and computer files to various internet locations several weeks before the Copenhagen Summit on climate change.

The contributions of women in climate change have received increasing attention in the early 21st century. Feedback from women and the issues faced by women have been described as "imperative" by the United Nations and "critical" by the Population Reference Bureau. A report by the World Health Organization concluded that incorporating gender-based analysis would "provide more effective climate change mitigation and adaptation."
Lisa Victoria Alexander is an international expert on heatwaves. She received the Dorothy Hill Medal for her research on climate extremes, the frequency and intensity of heatwaves, and has provided evidence that the frequency and intensity of heatwaves will be influenced by the quantity of anthropogenic greenhouse gas emissions, in particular carbon dioxide. She was a contributing author to the Intergovernmental Panel on Climate Change (IPCC) reports, including the fifth assessment report.
