Advancing Earth and Space Science for over 100 Years

AGU, founded in 1919, is the world’s largest Earth and space science association. Our global community of a half million researchers, policymakers, neighborhood leaders, and members of the science-supporting public are committed to advancing discovery in the geosciences and its benefits for humanity and the environment.

Science is critical to combating climate change. A delegation from AGU attended 2022 United Nations Climate Change Conference (COP27), as provisional observers. At COP27, which was held 6-14 November in Sharm El Sheikh, Egypt, AGU sought opportunities to collaborate with other organizations to demonstrate the crucial role of science in just-solutions, policy, and research.

AGU’s Ethical Framework for Climate Intervention

AGU is facilitating the development of an ethical framework to guide the research and possible deployment of climate change intervention measures. The framework is a collaborative effort that builds on the work of authoritative scientific and ethics bodies. 

We are convening a diverse panel of international advisors to take part in designing an ethical framework that will guide decisions about the potential use of intervention technologies. AGU is not taking a position about any specific methods. 

Our position on climate change is clear: immediate and coordinated actions to reduce greenhouse gas emissions and build resilience should be prioritized to protect human health, biodiversity, economic well-being, and global security. The ethical framework for climate intervention is a critical part of these actions.

Meet AGU’s COP27 Delegation

Susan Lozier, AGU President

Susan Lozier is Dean of the College of Sciences at Georgia Institute of Technology and the Betsy Middleton and John Clark Sutherland Chair. She received a bachelor’s degree in chemical engineering from Purdue University, completed a master’s degree in chemical engineering and a Ph.D. in physical oceanography, both from the University of Washington. Following postdoctoral studies at the Woods Hole Oceanographic Institution, Lozier joined the faculty of Duke University in 1992. In 2019 she assumed the deanship at Georgia Tech, where she is also a professor in the School of Earth and Atmospheric Sciences.

Susan is a physical oceanographer with an interest in large-scale ocean circulation. Overall, her research focuses on the ocean’s role in climate variability and climate change. She studies the meridional overturning circulation of the ocean and how that circulation impacts the transfer of heat and fresh water from one part of the ocean to another. Her research also focuses on understanding the physical controls on marine productivity. Lozier is the international lead for the Overturning in the Subpolar North Atlantic Program (OSNAP) observing system. OSNAP uses data from moored instruments, satellites, ocean gliders, and floats to provide estimates of the ocean's velocity, temperature and salinity fields. The project is providing much-needed data to understand the role of ocean circulation in the present and future climate and will help improve climate models that are used in the assessments by the International Panel on Climate Change.

Susan was the recipient of an NSF Early Career Award in 1996, was awarded a Bass Chair for Excellence in Research and Teaching in 2000, received a Duke University Award for Excellence in Mentoring in 2007, was named an American Meteorological Society Fellow in 2008, a Distinguished Professor at Duke in 2012, and a Fellow of the American Association for the Advancement of Science in 2015. She was named an American Geophysical Union (AGU) Fellow in 2014, received the AGU Ambassador Award in 2016 for leadership in the ocean sciences, and was elected to the American Academy of Arts and Sciences in 2020.

Susan has been serving as AGU President since January of 2021. The scientific organization of more than 60,000 members in 137 countries is a leading voice for science toward a sustainable future. She served as president of The Oceanography Society from 2014 to 2016.

Motivated by a commitment to diversity, she has contributed to the community through her mentoring efforts for students and early career scientists. She initiated and, for over a decade, led the Mentoring Physical Oceanography to Increase Retention (MPOWIR) program, which has served as a model for other mentoring efforts in earth and space science. In recognition of this work, she received the Outstanding Educator Award from the American Association of Women Geoscientists in 2010, and in 2017, was awarded the Joanne Simpson Mentorship Award from the American Meteorological Society for leadership in establishing a nationwide mentoring program for early-career female physical oceanographers and serving as a mentoring role model for the community.

Lisa Graumlich

Lisa Graumlich earned her undergraduate in botany and her master’s in geography from the University of Wisconsin at Madison, and her doctorate at the UW in Forest Resources. She has held faculty and leadership positions at the University of California at Los Angeles, the University of Arizona and Montana State University. Lisa is a fellow of the American Association for the Advancement of Science, the Ecological Society of America and the Aldo Leopold Leadership Program.


Her primary research interests are in paleoecology, and the ways that ecosystems and human societies adapt to climate change, with a special focus on severe and persistent drought. She pioneered the use of tree-ring data to understand long-term trends in climate, focusing on the mountains of western North America.


She has an interdisciplinary focus and a career-long interest in global climate change, especially with regard to how to best manage natural and human resources in an uncertain future, and she speaks frequently on climate change impacts and adaptation. Recently, she testified before the U.S. House of Representative Select Committee on Energy Independence and Global Warming on long-term climate variability.


Throughout her career she has demonstrated a strong commitment to increasing diversity, equity, and inclusion in science, technology, engineering, and mathematics (STEM). Graumlich is the first openly LGBTQ+ president-elect of AGU.

Ligia Pérez-CruzLigia Pérez-Cruz is a Senior Researcher at the National University of Mexico (UNAM) In Mexico City, and Chair of the Oceanographic Platforms Division that operates the Research Vessels “Justo Sierra” and “El Puma” of UNAM. The vessels have navigated and conduct oceanography and marine geophysics expeditions in the Eastern Pacific Ocean, the Gulf of California, the Gulf of Mexico and Caribbean Sea.


Perez-Cruz received a bachelor’s degree in Biology and a MSc degree in Marine Sciences from National University, with Suma Cum Laude. She spent two years as a micropaleontologist and Chair of the Scanning Electron Microscopy and Microanalysis Laboratory at the Mexican Institute of Petroleum (IMP). Afterwards, she got a Ph.D. in Marine Geology at UNAM, with Suma cum Laude. For four years she was a researcher for the Geophysical Exploration Division in the IMP, involved in the Drilling and MetOcean projects in the Gulf of Mexico.


Her research focuses on paleoclimate reconstructions marine surveys in the Gulf of California, the Chicxulub Impact Crater in Yucatan Peninsula and the Paleocene-Eocene Thermal Maximum and other hyperthermal events during the Cenozoic. She has participated in more than 40 oceanographic expeditions, including two International Ocean Discovery Program (IODP) expeditions 364 and 385, in the Drillship L/B Myrtle, and the JOIDES Resolution, respectively.


She has been navigating and studying the Gulf of California, investigating paleoclimate and ocean variability, mechanisms and teleconnections. Her research is inter- and multidisciplinary, using different tools of micropaleontology, geochemistry, isotopes, sedimentology and magnetic properties. Her research focuses on the marginal and axial Gulf basins, drilling and coring, looking at the water column, ocean currents and doing multibeam bathymetric surveys.


The Chicxulub crater studies cover a wide range of themes, including impact effects, extinctions, climate, the Paleocene-Eocene Thermal Maximum and other hyperthermal events during the Cenozoic Era. The significance of these studies is to understand how the life recovered after the mass extinction and consequences of global warming.


She is the past president of the Mexican Geophysical Union (UGM). In this position she contributed to promote the geosciences in Mexico and the Americas. The UGM Annual Meeting is the largest in Latin America with more than 1000 participants. She served as vice-president (president-elect) of UGM (2016 2017), Outreach Secretary of UGM (2012-2015).
