Michael Evan Mann is an American climatologist and geophysicist. He is the director of the Center for Science, Sustainability & the Media at the University of Pennsylvania. Mann has contributed to the scientific understanding of historic climate change based on the temperature record of the past thousand years. He has pioneered techniques to find patterns in past climate change and to isolate climate signals from noisy data.
The Climatic Research Unit (CRU) is a component of the University of East Anglia and is one of the leading institutions concerned with the study of natural and anthropogenic climate change.
Stephen McIntyre is a Canadian mining exploration company director, a former minerals prospector and semi-retired mining consultant whose work has included statistical analysis. He is the founder and editor of Climate Audit, a blog which analyses and discusses climate data. He is a critic of the temperature record of the past 1000 years and the data quality of NASA's Goddard Institute for Space Studies. He has made statistical critiques, with economist Ross McKitrick, of the hockey stick graph which shows that the increase in late 20th century global temperatures is unprecedented in the past 1,000 years.
Gavin A. Schmidt is a British climatologist, climate modeler and Director of the NASA Goddard Institute for Space Studies (GISS) in New York, and co-founder of the climate science blog RealClimate.
Climate Audit is a blog founded in 2005 by Steve McIntyre.
James Mark Court Delingpole is an English writer, journalist, and columnist who has written for a number of publications, including the Daily Mail, the Daily Express, The Times, The Daily Telegraph, and The Spectator. He is a former executive editor for Breitbart London, and has published several novels and four political books. He describes himself as a libertarian conservative. He has frequently published articles promoting climate change denial and expressing opposition to wind power.
Climate change denial is a form of science denial characterized by rejecting, refusing to acknowledge, disputing, or fighting the scientific consensus on climate change. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Climate change denial includes unreasonable doubts about the extent to which climate change is caused by humans, its effects on nature and human society, and the potential of adaptation to global warming by human actions. To a lesser extent, climate change denial can also be implicit when people accept the science but fail to reconcile it with their belief or action. Several studies have analyzed these positions as forms of denialism, pseudoscience, or propaganda.
Willard Anthony Watts is an American blogger who runs Watts Up With That?, a climate change denial blog that opposes the scientific consensus on climate change. A former television meteorologist and current radio meteorologist, he is also founder of the Surface Stations project, a volunteer initiative to document the condition of U.S. weather stations. The Heartland Institute helped fund some of Watts' projects, including publishing a report on the Surface Stations project, and invited him to be a paid speaker at its International Conference on Climate Change from 2008 to 2014.
Vincent Richard Gray was a New Zealand chemist, and a founder of the climate change denial organization New Zealand Climate Science Coalition.
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 Global Warming Policy Foundation (GWPF) is a charitable organisation in the United Kingdom whose aims are to challenge what it calls "extremely damaging and harmful policies" envisaged by governments to mitigate anthropogenic global warming. The GWPF, and some of its prominent members individually, have been characterised as practising and promoting climate change denial.
The Real Global Warming Disaster is a 2009 book by English journalist and author Christopher Booker in which he asserts that global warming cannot be attributed to humans, and then alleges how the scientific opinion on climate change was formulated.
Climatic Research Unit documents including thousands of e-mails and other computer files were stolen from a server at the Climatic Research Unit of the University of East Anglia in a hacking incident in November 2009. The documents were redistributed first through several blogs of global warming deniers, who alleged that the documents indicated misconduct by leading climate scientists. A series of investigations rejected these allegations, while concluding that CRU scientists should have been more open with distributing data and methods on request. Precisely six committees investigated the allegations and published reports, finding no evidence of fraud or scientific misconduct. The scientific consensus that global warming is occurring as a result of human activity remained unchanged by the end of the investigations.
Judith A. Curry is an American climatologist and former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. Her research interests include hurricanes, remote sensing, atmospheric modeling, polar climates, air-sea interactions, climate models, and the use of unmanned aerial vehicles for atmospheric research. She was a member of the National Research Council's Climate Research Committee, published over a hundred scientific papers, and co-edited several major works. Curry retired from academia in 2017 at age 63, coinciding with her public climate change skepticism.
Andrew William Montford is a British writer and editor who is the owner of the Bishop Hill blog. He is the author of The Hockey Stick Illusion (2010).
The Hockey Stick Illusion: Climategate and the Corruption of Science is a book written by Andrew Montford and published by Stacey International in 2010, which promotes climate change denial.
Berkeley Earth is a Berkeley, California-based independent 501(c)(3) non-profit focused on land temperature data analysis for climate science. Berkeley Earth was founded in early 2010 to address the major concerns from outside the scientific community regarding global warming and the instrumental temperature record. The project's stated aim was a "transparent approach, based on data analysis." In February 2013, Berkeley Earth became an independent non-profit. In August 2013, Berkeley Earth was granted 501(c)(3) tax-exempt status by the US government. The primary product is air temperatures over land, but they also produce a global dataset resulting from a merge of their land data with HadSST.
Marc Morano is a former Republican political aide who founded and runs the website ClimateDepot.com. ClimateDepot is a project of the Committee for a Constructive Tomorrow (CFACT), a US non-profit organisation that promotes climate change denial.
The history of climate change policy and politics refers to the continuing history of political actions, policies, trends, controversies and activist efforts as they pertain to the issue of climate change. Climate change emerged as a political issue in the 1970s, when activist and formal efforts sought to address environmental crises on a global scale. International policy regarding climate change has focused on cooperation and the establishment of international guidelines to address global warming. The United Nations Framework Convention on Climate Change (UNFCCC) is a largely accepted international agreement that has continuously developed to meet new challenges. Domestic policy on climate change has focused on both establishing internal measures to reduce greenhouse gas emissions and incorporating international guidelines into domestic law.
