He retired from the Lawrence Livermore National Laboratory in 2021 and is now a Distinguished Scholar in Residence at Woods Hole Oceanographic Institution. He also worked at the Max Planck Institute for Meteorology from 1987 to 1992. He specializes mainly in statistical analysis of climate data sets, and detection/attribution of climate change forcings.
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 American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people. AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C.
Kevin Edward Trenberth worked as a climate scientist in the Climate Analysis Section at the US National Center for Atmospheric Research (NCAR). He was a lead author of the 1995, 2001 and 2007 IPCC assessment reports. He also played major roles in the World Climate Research Programme (WCRP), for example in its Tropical Oceans Global Atmosphere program (TOGA), the Climate Variability and Predictability (CLIVAR) program, and the Global Energy and Water Exchanges (GEWEX) project.
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.
The IPCC Third Assessment Report (TAR), Climate Change 2001, is an assessment of available scientific and socio-economic information on climate change by the IPCC. Statements of the IPCC or information from the TAR were often used as a reference showing a scientific consensus on the subject of global warming. The Third Assessment Report (TAR) was completed in 2001 and consists of four reports, three of them from its Working Groups: Working Group I: The Scientific Basis; Working Group II: Impacts, Adaptation and Vulnerability; Working Group III: Mitigation; Synthesis Report. A number of the TAR's conclusions are given quantitative estimates of how probable it is that they are correct, e.g., greater than 66% probability of being correct. These are "Bayesian" probabilities, which are based on an expert assessment of all the available evidence.
Naomi Oreskes is an American historian of science. She became Professor of the History of Science and Affiliated Professor of Earth and Planetary Sciences at Harvard University in 2013, after 15 years as Professor of History and Science Studies at the University of California, San Diego.
Susan Solomon is an American atmospheric chemist, working for most of her career at the National Oceanic and Atmospheric Administration (NOAA). In 2011, Solomon joined the faculty at the Massachusetts Institute of Technology, where she serves as the Ellen Swallow Richards Professor of Atmospheric Chemistry & Climate Science. Solomon, with her colleagues, was the first to propose the chlorofluorocarbon free radical reaction mechanism that is the cause of the Antarctic ozone hole.
Kenneth Caldeira is an American atmospheric scientist. His areas of research include ocean acidification, climate effects of trees, intentional climate modification, interactions in the global carbon cycle/climate system, and sustainable energy.
Lynne Talley is a physical oceanographer at Scripps Institution of Oceanography known for her research into the large-scale circulation of water masses in the global ocean.
Richard Chapin James Somerville is an American climate scientist who is a Distinguished Professor Emeritus at Scripps Institution of Oceanography at the University of California, San Diego, where he has been a professor since 1979.
Katharine Anne Scott Hayhoe is a Canadian atmospheric scientist. She is a Paul Whitfield Horn Distinguished Professor and an Endowed Chair in Public Policy and Public Law at the Texas Tech University Department of Political Science. In 2021, Hayhoe joined the Nature Conservancy as Chief Scientist.
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."
Tamsin Edwards is a British climate scientist and Professor at King's College London. She is a popular science communicator and writes for the Public Library of Science (PLOS).
Kate Marvel is a climate scientist and science writer based in New York City. She is a senior scientist at Project Drawdown and was formerly an associate research scientist at NASA Goddard Institute for Space Studies and Columbia Engineering's Department of Applied Physics and Mathematics.
Rafe Pomerance is an American environmentalist. He is a Distinguished Senior Arctic Policy Fellow of the Woodwell Climate Research Center. Since the late 1970s, he has played a key role in raising awareness of the risks of climate change for United States policy-makers. His role during the period 1979 to 1989 is detailed in the book Losing Earth, by Nathaniel Rich.
Elisabeth Holland is an American climate scientist who focuses on how the carbon and nitrogen cycles interact with earth systems. She has become a key player in the international climate debate. She is currently a professor of climate change at the University of the South Pacific. She is also the director of the Pacific Center for Environmental and Sustainable Development.
Lai-yung Ruby Leung is an atmospheric scientist internationally recognized in the field of Earth Systems modeling and hydrologic processes. She is known for her contributions to the development of local climate models, and for her understanding of the consequences of climate change. Her interests are diverse across mountain hydrometeorology, aerosol-cloud interactions, orographic precipitation and climate extremes.
Maura E. Hagan is a Professor of Physics and Dean of the College of Science at Utah State University. She is a Fellow of both the American Meteorological Society and the American Geophysical Union, and was elected a member of the National Academy of Sciences in 2019.
Climate communication or climate change communication is a field of environmental communication and science communication focused on discussing the causes, nature and effects of anthropogenic climate change.
