The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) set up the IPCC in 1988. The United Nations endorsed the creation of the IPCC later that year. It has a secretariat in Geneva, Switzerland, hosted by the WMO. It has 195 member states who govern the IPCC. The member states elect a bureau of scientists to serve through an assessment cycle. A cycle is usually six to seven years. The bureau selects experts in their fields to prepare IPCC reports. There is a formal nomination process by governments and observer organizations to find these experts. The IPCC has three working groups and a task force, which carry out its scientific work.
Bert Rickard Johannes Bolin was a Swedish meteorologist who served as the first chairman of the Intergovernmental Panel on Climate Change (IPCC), from 1988 to 1997. He was professor of meteorology at Stockholm University from 1961 until his retirement in 1990.
Rajendra Kumar Pachauri was the chairman of the Intergovernmental Panel on Climate Change (IPCC) from 2002 to 2015, during the fourth and fifth assessment cycles. Under his leadership the IPCC was awarded the Nobel Peace Prize in 2007 and delivered the Fifth Assessment Report, the scientific foundation of the Paris Agreement. He held the post from 2002 until his resignation in February 2015 after facing multiple allegations of sexual harassment. In March 2022, he was exonerated of the sexual harassment allegations. He was succeeded by Hoesung Lee. Pachauri assumed his responsibilities as the Chief Executive of The Energy and Resources Institute in 1981 and led the institute for more than three decades and demitted office as Executive Vice Chairman of TERI in 2016. Pachauri, universally known as Patchy, was an internationally recognized voice on environmental and policy issues, and his leadership of the IPCC contributed to the issue of human-caused climate change becoming recognized as a matter of vital global concern.
Jonathan Michael Gregory is a climate modeller working on mechanisms of global and large-scale change in climate and sea level on multidecadal and longer timescales at the Met Office and the University of Reading.
Gary Wynn Yohe is the Huffington Foundation Professor of Economics and Environmental Studies at Wesleyan University, Middletown, Connecticut. He holds a PhD from Yale University.
Mohan Munasinghe is a Sri Lankan physicist, engineer and economist with a focus on energy, water resources, sustainable development and climate change. He was the 2021 Blue Planet Prize Laureate, and Vice-Chair of the Intergovernmental Panel on Climate Change (IPCC), which shared the 2007 Nobel Peace Prize with former Vice-President of the United States Al Gore. Munasinghe is the Founder Chairman of the Munasinghe Institute for Development. He has also served as an honorary senior advisor to the government of Sri Lanka since 1980.
Dork Sahagian is an Armenian American climate scientist. He is the Director of the Environmental Initiative at Lehigh University in Bethlehem, Pennsylvania. He invented a technique for calculating the Earth's air pressure in the past, based on the difference in the size of the bubbles in cooled volcanic lava. He received Nobel Peace Prize in 2007 as a part of IPCC.
The 2007 Nobel Peace Prize was shared, in two equal parts, between the Intergovernmental Panel on Climate Change (IPCC) and United States former vice president, Al Gore "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change".
Arturo Villavicencio is an Ecuadorian environmental researcher. He was nominated by Denmark in 1995 for the Intergovernmental Panel on Climate Change (IPCC) and contributed to its fourth assessment report. The work of the IPCC, including the contributions of many scientists, was recognised by the joint award of the 2007 Nobel Peace Prize to the IPCC and Al Gore.
William R. Moomaw is the Professor Emeritus of International Environmental Policy at the Fletcher School, Tufts University. Moomaw has worked at the intersection of science and policy, advocating for international sustainable development. His activities have included being a long-time contributor to the Intergovernmental Panel on Climate Change and an author on the seminal "Perspective" paper on proforestation.
Venkatachalam Ramaswamy is the Director of the Geophysical Fluid Dynamics Laboratory of the National Oceanic and Atmospheric Administration (NOAA) Office of Oceanic and Atmospheric Research (OAR), studying climate modeling and climate change. "A leading climate scientist", his work is cited as supporting evidence for significant stratospheric climate change. He focuses in particular on radiative transfer models and the hydrologic cycle in the atmosphere. He has actively supported the development of supercomputing approaches that enable researchers to achieve higher resolution and greater complexity in climate models. As a lead author involved in the Intergovernmental Panel on Climate Change (IPCC), Ramaswamy's contributions was recognised by the joint award of the 2007 Nobel Peace Prize to the IPCC.
Raymond Ward Arritt was an American agronomist whose research focused on agricultural meteorology. He taught at Iowa State University from 1993 until his death in 2018. At Iowa State, he was responsible for operating the meteorological data repository Iowa Environmental Mesonet. He was one of three Iowa State faculty who contributed to the fourth (AR4) Intergovernmental Panel on Climate Change (IPCC) assessment report, which led to the IPCC sharing the 2007 Nobel Peace Prize with Al Gore.
Lučka Kajfež Bogataj is a Slovenian climatologist, specialist in agricultural meteorology.
Wei-Min Hao is a Taiwanese-American atmospheric chemist, climatologist, and currently works in the United States Department of Agriculture. His work directly contributed to the reason for awarding the 2007 Nobel Peace Prize. He is a member of the United States Agency for International Development (USAID) and an author of the Intergovernmental Panel on Climate Change (IPCC).
Richard Samson Odingo was a Kenyan scientist who was the vice chairman of the Intergovernmental Panel on Climate Change (IPCC) when it was awarded the Nobel Peace prize in 2007 with Al Gore. He had held this position for more than 20 years prior. He was awarded full Professorship at the University of Nairobi in Geography in 1987. He has been a consultant of several international agencies including multiple United Nations Agencies and has taught for many years at the University of Nairobi.
Opha Pauline Dube is a Botswanan environmental scientist and Associate Professor in the Department of Environmental Science at the University of Botswana.
