John Imbrie was an American paleoceanographer who significantly advanced the understanding of Earth's climate history. He co-developed the orbital theory of ice ages, providing empirical evidence that variations in Earth's orbit, known as Milankovitch cycles, drive long-term climate shifts. Imbrie w...

James Hays is an American paleoclimatologist and oceanographer known for his research on deep-sea sediment cores. He was a co-author, alongside John Imbrie and Nicholas Shackleton, of the 1976 paper 'Variations in the Earth's Orbit: Pacemaker of the Ice Ages,' which analyzed Indian and Pacific Ocean...

Willi Dansgaard (1922–2011) was a Danish paleoclimatologist who pioneered the use of oxygen isotope analysis in ice cores to reconstruct historical climate data. His research demonstrated that the ratio of oxygen-18 to oxygen-16 in ice could be used to determine past atmospheric temperatures. Workin...

Roger Revelle (1909–1991) was a prominent American oceanographer who served as the director of the Scripps Institution of Oceanography. He was a pioneer in the study of global warming, co-authoring a landmark 1957 paper with Hans Suess that predicted atmospheric carbon dioxide accumulation from foss...

Eunice Newton Foote was an American scientist whose 1856 experiments examined how gases respond to solar heating. Using glass cylinders containing gases including carbon dioxide, oxygen, hydrogen, and air, she found that carbon dioxide warmed more and retained heat longer, then argued that changes i...

James Kennett is a New Zealand-born marine geologist widely recognized for helping to establish the field of paleoceanography. He utilized deep-sea sediment cores to study the history of the Earth's oceans, documenting major climatic shifts throughout the Cenozoic era. His foundational research spec...

Hans Oeschger was a Swiss physicist and pioneer in paleoclimatology who spent his career at the University of Bern. He co-invented the Oeschger counter for measuring weak radioactivity and developed early ice core analytical techniques. Using these methods, he co-identified the rapid, millennial-sca...

William F. Ruddiman is an American paleoclimatologist and professor emeritus at the University of Virginia. He is best known for formulating the early Anthropocene hypothesis, published in his 2005 book "Plows, Plagues, and Petroleum," which argues that human agriculture and deforestation began rais...

Timothy Lenton is a British Earth system scientist at the University of Exeter, specializing in the study of climate tipping points and biosphere feedbacks. He is known for his collaborative work with James Lovelock in developing and refining the Gaia theory, which models the Earth as a self-regulat...

Jan Veizer is a Slovak-Canadian geochemist whose research focuses on reconstructing ancient ocean chemistry and climate through isotopic analysis of sedimentary carbonates. He served as a professor at the University of Ottawa and produced an influential oxygen isotope curve spanning the Phanerozoic...

Isabel Montañez is an American paleoclimatologist and geologist at the University of California, Davis. She is known for using isotope geochemistry to reconstruct ancient atmospheric CO₂ concentrations and climate dynamics during Paleozoic glaciations. Her research integrates field studies, geochemi...

American geochemist at Penn State known for research on ocean anoxic events and hydrogen sulfide outgassing as drivers of marine mass extinctions.

Maureen Raymo is an American paleoclimatologist and marine geologist who studies long-term climate change using marine sediments, geochemical records, and evidence of past sea levels. She helped develop the hypothesis that uplift of the Himalayas and Tibetan Plateau increased chemical weathering, wh...

Samuel Epstein was a Canadian-American geochemist whose research at the California Institute of Technology pioneered the use of stable oxygen isotope geochemistry. By developing techniques to measure isotope ratios in geologic materials, he established foundational methods for determining ancient Ea...

Gerard C. Bond (1940–2005) was an American paleoclimatologist at Columbia University's Lamont-Doherty Earth Observatory. He is best known for identifying millennial-scale climate fluctuations during the Holocene epoch, which are now commonly referred to as Bond cycles. Bond discovered these cycles b...

Cesare Emiliani (1922–1995) was an Italian-American geologist who pioneered the use of oxygen isotope stratigraphy in the 1950s, applying it to deep-sea sediment cores to reconstruct past climates. His work established that glacial-interglacial cycles had occurred repeatedly, providing crucial data...
