Dorthe Dahl-Jensen's research has focused on the reconstruction of past climates from deep ice cores drilled on the Greenland ice sheet. She has led several deep drilling efforts in Greenland, including the NEEM and EGRIP projects and participated in the EPICA project in Antarctica. The ice core data have yielded detailed knowledge on climate conditions during past glacial and interglacial periods and Dorthe's group has intensively studied periods of rapid warming during the last glacial period, the Dansgaard-Oeschger events. Dorthe has also used borehole thermometry to reconstruct past temperature changes and developed ice-flow models used in the dating of ice cores. She studies the mechanical properties of ice, the development of anisotropy in ice sheets and the flow behaviour of ice streams. As research chair at the University of Manitoba, Dorthe focuses on the effects of freshwater input to the ocean due to increased melting of the ice in Greenland and Arctic Canada.
Valerie Masson-Delmotte's research has evolved around documenting past climate variability using natural archives (ice cores, tree rings) and stable isotope tools. She has studied the climate variability of the last centuries, abrupt climate changes during the last glacial period and the glacial-interglacial cycles. She has worked on projects in Greenland, Antarctica, Tibet, and Europe. She has also used climate models to simulate past changes on different spatial and temporal scales. Valerie has a long-term involvement in the sharing of results from climate science with stakeholders, children and the general public. She has also been involved in multi-disciplinary research projects and committee work with scientists from the life, health, and social sciences on topics related to water, climate-change impacts, perception, adaptation and mitigation strategies.
Eric Rignot studies the interactions of ice and climate, in particular to determine how the ice sheets in Antarctica and Greenland will respond to climate change in the coming century and how they affect global sea level. His research groups at UC Irvine and JPL combine satellite remote sensing techniques (imaging radar interferometry, laser altimetry, optical imagery), airborne geophysical surveys (gravity, radar depth sounder), shipborne surveys (multi-beam echo sounding, conductivity-temperature-depth profiles, robotic devices), and field surveys (ground penetrating radars, ground portable radar interferometer, GPS) and numerical modeling (ice sheet models ISSM, and ocean models MITgcm). The group's work is about the causes and effects of climate change on ice sheets, but also connects with solutions to climate change and adaptation and mitigation strategies.

His research interests include atmosphere–sea-ice interactions, synoptic climatology, boundary-layer problems, and climate change. He has conducted field work in the Canadian Arctic on sea ice and ice caps, and on the Alaskan tundra. Efforts over the past ten years have increasingly focused on trying to make sense of the rapid environmental changes being observed in the Arctic. Mark is a leading authority on Arctic climate and his books include the award-winning textbook The Arctic Climate System (2005) and Brave New Arctic: The Untold Story of the Melting North, which has received critical acclaim for its impact on audiences beyond academia.
Julia Boike's passion is the multidisciplinary science of permafrost – understanding the the frozen Earth and how it is tied to our global climate system. She has travelled to Arctic field sites every year for more than 25 years and observed the on-going changes at remote places, such as Arctic Canada, Alaska, Eastern Siberia, and Svalbard. She uses innovative instruments that allow her to observe these changes at different scales, from the microscopic structure of snow and permafrost to the landscape-sized distribution of patterned ground. Together with her research group she undertakes long-term studies to find out more about how permafrost affects the exchange of energy and water between the ground and the air. Working together with climate modellers, her data provide the basis for including permafrost in models of the Earth’s climate system.
Olga Makarieva's scientific interests are cold region hydrology with focus on river flow-permafrost interactions and their changes in a non-stationary environment. She has worked on the development and enhancement of a process-oriented, robust, hydrological model, which can be applied in different permafrost landscapes with the ability to use observable characteristics of watersheds as parameters. Her research is focused on the impact of climate and landscape changes on the hydrological regime, engineering calculations of runoff, remote sensing data, the transformation of the hydrological regime, groundwater, the influence of the active layer of permafrost on runoff formation and mountain hydrology.

Peter Bijl's research interests can be summarized in the theme: Climatic and environmental evolution of Antarctica and the Southern Ocean. He uses sedimentary archives from drilling programs now known as the International Ocean Discovery Program (IODP). He has worked on the reconstruction of the climatological evolution of Antarctica and the Southern Ocean in the Cenozoic transition from the hot early Eocene to the middle- and late Eocene cooling and the Oligocene-Neogene icehouse. He has also studied the consequences of the formation of the Antarctic Ice Sheet for ecosystems, sea level and ocean current systems. He currently leads the research project OceaNice, funded by the European Research Council, focussing on the role of ocean conditions on the melt of Antarctic ice sheets during past warm climates. In 2014, Peter recieved the EGU Arne Richter Award for outstanding young scientists and in 2018 the Heineken Young Scientist Award from the Royal Netherlands Society of Sciences.
Robert DeConto studies past and future Antarctic climate, the history of the Antarctic ice sheet and its potential instability due to climatic warming. He pioneered a data-model integration strategy that was key to the success of the ANDRILL programme, central to the SCAR Antarctic Climate Evolution (ACE) and Past Antarctic Ice Sheet Evolution (PAIS) scientific research programmes, and eventually adapted by the International Ocean Drilling Program’s (IODP) science plan with an emphasis on the role of the South Polar region in climate evolution and sea level history. Over the last decade, Rob has worked with colleagues to build on this basic methodology in a series of influential papers, incorporating new and significant ice loss processes that provide improved comparisons between model results and geological data, with recent models predicting a doubling in the amount of sea level rise by the end of the century and beyond.
Tandong Yao’s research addresses how the cryosphere in the Third Pole is changing and how its change is interacting with the hydrosphere and atmosphere and impacting the functioning of the Asian Water Towers. His focus is largely on the cryosphere changes recorded by glacier mass balance and ice core climate parameters in the Third Pole region. His research reveals the north-south contrast pattern of glacier fluctuations in the Third Pole under influence of the westerly and Indian monsoon interaction. He has been co-chairing the Third Pole Environment program since 2009. This international program is focusing not only on Third Pole environment change, but also on knowledge transfers to raise public awareness of climate changes and to enhance human adaptation to the changing environment. Prof. Tandong Yao is a member of the Chinese Academy of Sciences.
