Paleoclimatology is the scientific study of climates predating the invention of meteorological instruments, when no direct measurement data were available. As instrumental records only span a tiny part of Earth's history, the reconstruction of ancient climate is important to understand natural variation and the evolution of the current climate.
In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history. Reliable global records of climate only began in the 1880s, and proxies provide the only means for scientists to determine climatic patterns before record-keeping began.
Paleolimnology is a scientific sub-discipline closely related to both limnology and paleoecology. Paleolimnological studies focus on reconstructing the past environments of inland waters using the geologic record, especially with regard to events such as climatic change, eutrophication, acidification, and internal ontogenic processes.

She specialized in environmental phenomena and more specifically the study of lacustrine sediments from ancient lakes in Africa and Asia region. F. Gasse had special impact in starting the first research projects that aim at rebuilding paleoclimatic variations and Quaternary paleoenvironments in different regions and precisely: the Sahara and the Sahel, East Africa and Madagascar, Western (Caspian) and Southern (Tibet), and in the Middle East (Lebanon). She was a member of PAGES / The International Geosphere-Biosphere Programme.
Amy Leventer is an American Antarctic researcher specialising in micropaleontology, with specific research interests in marine geology, marine biology, and climate change. Leventer has made over a dozen journeys to the Antarctic, which began at the age of 24 and led to the pursuit of her PhD.
Herbert Edgar Wright Jr. was an American Quaternary scientist. He contributed to the understanding of landscape history and environmental changes over the past 100,000 years in many parts of the world. He studied arid-region geomorphology and landscape evolution, as well as glacial geology and climate history. His study of these topics led him to the study of vegetation development and environmental history and allowed him to define the timing and mechanisms of climate-driven vegetational shifts in North America during the last 18,000 years and to recognize the role of natural fire in the dynamics of northern coniferous forests. He applied these insights to wilderness conservation and landscape management. He covered many other aspects of paleoecology including lake development and paleolimnology, and the history and development of the vast patterned peatlands of Minnesota and elsewhere in the Northern Hemisphere. Although his work was concentrated in Minnesota, he was also involved in a major synthesis of global paleoclimatology. Beyond Minnesota and the Great Lakes region, Wright studied a wide range of research questions elsewhere in North America, and in the Near East, Europe, Asia, Latin America, and Antarctica. He advised over 75 graduate students and mentored many more students, visitors, and colleagues worldwide.

Amelia E. Shevenell is an American marine geologist who specializes in high-latitude paleoclimatology and paleoceanography. She is currently a Professor in the College of Marine Science at the University of South Florida. She has made notable contributions to understanding the history of the Antarctic ice sheets and published in high-impact journals and, as a result, was awarded full membership of Sigma Xi. She has a long record of participation in international ocean drilling programs and has served in leadership positions of these organizations. Shevenell served as the elected Geological Oceanography Council Member for The Oceanography Society (2019-2021).
Paleohydrology, or palaeohydrology, is the scientific study of the movement, distribution, and quality of water on Earth during previous periods of its history. The discipline uses indirect evidence to infer changes in deposition rates, the existence of flooding, changes in sea levels, changes in groundwater levels and the erosion of rocks. It also deals with alterations in the floral and faunal assemblages which have come about in previous periods because of changes in hydrology.
