Naomi Oreskes Biography – Early Life, Career, Climate Science & Achievements
Naomi Oreskes is an American historian of science, geologist, author, professor and public speaker whose work has helped explain how scientific knowledge is created, how scientific consensus develops and how organized campaigns can spread doubt about established scientific findings.
She is best known internationally for her research on climate change, scientific consensus and disinformation, particularly through her influential 2010 book Merchants of Doubt, co-authored with historian Erik M. Conway.
Oreskes' career is unusual because she began as a working geologist before becoming a historian of science. That combination gave her a rare perspective: she understood scientific research from direct experience while also becoming interested in how scientific institutions, evidence and expert communities work. (histsci.fas.harvard.edu)
Her 2004 paper, “The Scientific Consensus on Climate Change,” became one of the most widely discussed pieces of research in the public climate debate. She examined 928 peer-reviewed scientific abstracts published between 1993 and 2003 and found no paper in the sample that rejected the consensus position on human-caused global warming. (pubmed.ncbi.nlm.nih.gov)
Her later work investigated why the public can be given the impression that scientists are deeply divided even when substantial scientific agreement exists.
Through books including Merchants of Doubt, Why Trust Science?, Science on a Mission and The Big Myth, Oreskes has examined the relationship between science, government, business, politics and public trust.
As of 2026, she is the Henry Charles Lea Professor of the History of Science and an Affiliated Professor of Earth and Planetary Sciences at Harvard University. (histsci.fas.harvard.edu)

Who Is Naomi Oreskes?
Naomi Oreskes is a scholar who studies how science works within society.
Her research asks questions such as:
How do scientists establish knowledge?
Why do scientists sometimes disagree?
How does scientific consensus develop?
Why should the public trust scientific expertise?
How can misinformation create false impressions of scientific uncertainty?
How have political and economic interests influenced debates about science?
Her work is particularly important in the context of climate change.
The scientific evidence for human-caused climate change has accumulated over decades, yet public debates have sometimes portrayed climate science as if scientists remain fundamentally divided.
Oreskes has spent much of her career examining why that gap between scientific knowledge and public perception exists.
Harvard describes her research areas as including agnotology, the political economy of scientific knowledge, the history and philosophy of Earth and environmental sciences, science and technology studies, and the history of climate-change disinformation. (histsci.fas.harvard.edu)
Naomi Oreskes Early Life
Naomi Oreskes was born in New York City in 1958.
She grew up in a family with strong connections to education and science.
Her father, Irwin Oreskes, was a scientist and academic, while her mother, Susan Eileen Oreskes, was a teacher.
Growing up in New York City, Naomi developed broad intellectual interests.
She was interested in mathematics and science but also enjoyed literature and history.
This combination eventually became extremely important to her career.
She later recalled that, as a student, she was sometimes told that her interests in science, history, mathematics and literature did not seem to fit together.
Eventually, geology provided a way to combine her interests in science and the history of the Earth. (sustainability.stanford.edu)
Discovering Geology
Oreskes became attracted to geology partly because it offered the opportunity to work outdoors and investigate the history recorded in rocks and minerals.
She has described her fascination with minerals and crystal structures as one of the reasons geology appealed to her.
For her, rocks were not simply objects.
They were evidence.
They contained clues about Earth's past.
That evidence-based approach would later become central to her work as a historian of science.
Naomi Oreskes Education
Naomi Oreskes attended Stuyvesant High School in New York City.
She later moved to the United Kingdom for university.
In 1981, she completed a Bachelor of Science degree at the Royal School of Mines at Imperial College London.
She specialized in geology/mining geology.
Her time at the Royal School of Mines was historically significant.
She was one of only a small number of women studying geology there and later became the first woman to earn a degree in mining from the institution, according to Stanford's account of her career. (sustainability.stanford.edu)
She then returned to the United States and pursued graduate research at Stanford University.
In 1990, she earned her PhD through Stanford's interdisciplinary Graduate Special Program in Geological Research and History of Science. (histsci.fas.harvard.edu)
This combination of geology and history became the foundation of her unusual academic career.
Naomi Oreskes as a Geologist
After completing her undergraduate education, Oreskes worked as an exploration geologist in Australia.
From 1981 to 1984, she worked for Western Mining Corporation.
Her work took her into the Australian outback.
This was not simply classroom geology.
She was working in the field, examining rocks and geological structures and contributing to mineral exploration.
According to Stanford, Oreskes was often the only woman in her exploration group and sometimes the only woman within a very large geographical area. (sustainability.stanford.edu)
The experience taught her valuable lessons about field science and about working in a traditionally male-dominated profession.
Naomi Oreskes and the Challenges of Being a Woman in Geology
Oreskes entered geology at a time when women were still significantly underrepresented in the field.
At the Royal School of Mines, faculty members reportedly debated whether she should even be allowed to study mining geology because of concerns about whether a woman would be able to find employment.
She proved those assumptions wrong.
She entered the profession and worked as an exploration geologist in Australia.
Her experience was important because it gave her firsthand knowledge of the professional culture of Earth science.
That experience later influenced her interest in the history of women in science and the social structures surrounding scientific knowledge.
Naomi Oreskes PhD and Career Change
While studying at Stanford, Oreskes became increasingly interested in the history of science.
She began asking questions that went beyond geological evidence itself.
How did scientists decide which theories were credible?
Why were some scientific ideas accepted while others were rejected?
How did evidence, institutions and professional communities influence scientific conclusions?
These questions led her toward a new academic field.
Instead of remaining solely a geologist, she became a historian of science.
That transition became one of the most important decisions of her career.
Naomi Oreskes Academic Career
After completing her PhD, Oreskes began teaching and conducting research at several universities.
She held academic positions at:
Dartmouth College
New York University
University of California, San Diego
Harvard University
At UC San Diego, she became Professor of History and Science Studies and also held a role connected to geosciences.
She later joined Harvard University.
Her career demonstrates the unusual intersection of:
Geology + History + Philosophy + Science Policy + Environmental Studies
That interdisciplinary approach became one of her greatest strengths.
Naomi Oreskes and the History of Plate Tectonics
One of Oreskes' early research interests was the history of Earth sciences.
She examined how major scientific theories develop and how scientific communities respond to new ideas.
Her book The Rejection of Continental Drift: Theory and Method in American Earth Science, published in 1999, examined why American geologists were initially resistant to continental drift.
This was an important historical question.
Today, plate tectonics is a foundational concept in Earth science.
But scientific acceptance did not happen instantly.
Oreskes showed that scientific debates are influenced not only by evidence but also by research traditions, institutions, professional assumptions and available methods.
Her work demonstrated that understanding science sometimes requires understanding the social history of science.
Naomi Oreskes and Scientific Consensus
Scientific consensus became one of the central themes of Oreskes' career.
She was interested in how scientists collectively establish confidence in a scientific claim.
This eventually led to her most famous climate-related research.
In 2004, she published the influential essay:
“The Scientific Consensus on Climate Change.”
The paper appeared in Science.
She analyzed 928 abstracts from peer-reviewed scientific papers published between 1993 and 2003.
Her analysis found no paper in the sample that explicitly rejected the consensus position on human-caused global warming. (pubmed.ncbi.nlm.nih.gov)
The paper received enormous public attention.
It helped shift the conversation from:
“Do scientists agree?”
to:
“Why does the public sometimes think scientists do not agree?”
What Did Naomi Oreskes' 2004 Climate Study Find?
Oreskes examined scientific literature rather than conducting a survey of individual scientists.
This distinction is important.
Her research analyzed published scientific papers related to global climate change.
Of the 928 abstracts she examined, none explicitly rejected the consensus that human activities contribute to observed global warming.
Later research using different methodologies has produced estimates of very high scientific agreement about human-caused climate change.
The broader literature has therefore continued to investigate and refine how scientific consensus should be measured. (iopscience.iop.org)
Naomi Oreskes and Merchants of Doubt
The 2004 climate paper changed Oreskes' public career.
She began receiving criticism and questions about why climate science was being publicly challenged despite strong scientific agreement.
That led her to investigate the history of organized doubt more deeply.
Her research eventually resulted in the book:
Merchants of Doubt
Published in 2010, the book was co-authored with historian Erik M. Conway.
The book investigated historical campaigns in which scientific uncertainty was emphasized in public debates about issues including:
Tobacco
Acid rain
The ozone layer
DDT
Climate change
The authors argued that certain scientists and organized interests played roles in promoting doubt about scientific findings.
Harvard describes the book as examining how a small number of scientists helped obscure the truth on issues ranging from tobacco smoke to global warming. (histsci.fas.harvard.edu)
Naomi Oreskes and Erik Conway
Erik M. Conway became one of Oreskes' most important collaborators.
Together, they wrote several influential books.
Their collaboration brought together different areas of expertise.
Oreskes contributed her background in Earth sciences and history of science.
Conway brought expertise in the history of technology, NASA and scientific institutions.
Together, they investigated how scientific information can become entangled with politics, economics and ideology.
Their partnership produced Merchants of Doubt and later The Collapse of Western Civilization and The Big Myth.
Naomi Oreskes and The Merchants of Doubt Documentary
The success of Merchants of Doubt eventually led to a documentary film.
The documentary, directed by Robert Kenner, was released in 2014.
Oreskes appeared in the film and served as a consultant during its production.
The documentary brought the book's argument to a much larger public audience.
It explored how doubt and uncertainty can be used strategically in public debates about scientific issues.
The film was distributed by Sony Pictures Classics. (histsci.fas.harvard.edu)
Naomi Oreskes and Agnotology
A major concept in Oreskes' recent work is agnotology.
Agnotology is the study of socially produced ignorance.
In simple terms, it asks:
How does society come to not know something?
Ignorance is not always created because information does not exist.
Sometimes information exists but is:
Suppressed
Ignored
Misrepresented
Distracted from
Overwhelmed by conflicting claims
Presented as more uncertain than it really is
Oreskes uses this framework to examine climate disinformation and other controversies involving science.
Harvard lists agnotology among her primary areas of research. (histsci.fas.harvard.edu)
Naomi Oreskes and Why Trust Science?
In 2019, Oreskes published Why Trust Science?
The book examines a fundamental question:
Why should society trust scientific knowledge?
Oreskes argues that scientific trustworthiness does not come from scientists being perfect.
Scientists make mistakes.
Scientific conclusions can change.
Research can be incomplete.
Instead, she emphasizes the social process through which scientific claims are tested, criticized, reviewed and evaluated by communities of experts. (histsci.fas.harvard.edu)
This became particularly relevant during a period when public trust in experts and institutions was under intense pressure.
Naomi Oreskes and Science on a Mission
In 2021, Oreskes published Science on a Mission: How Military Funding Shaped What We Do and Don't Know about the Ocean.
The book examined the history of American oceanography during the Cold War and its relationship with military funding.
Her argument was not that military involvement made ocean science invalid.
Instead, she investigated how funding priorities can shape:
Research questions
Scientific institutions
Technologies
Knowledge production
What scientists choose to investigate
The book reflects a central theme of Oreskes' career:
Science does not exist in isolation from society.
Naomi Oreskes and The Big Myth
In 2023, Oreskes and Erik Conway published The Big Myth: How American Business Taught Us to Loathe Government and Love the Free Market.
The book expanded their research beyond climate science.
It investigated the historical development of free-market ideology in the United States and the role of business interests in shaping public attitudes toward government.
The book argues that political ideas about markets and government are not simply timeless truths but have histories that can be studied.
Harvard lists The Big Myth among Oreskes' major publications. (histsci.fas.harvard.edu)
Naomi Oreskes and Climate Change
Climate change remains one of the most important subjects in Oreskes' public work.
However, her role is different from that of a climate modeler or atmospheric scientist.
She primarily studies:
The history of climate science
Scientific consensus
Public understanding of science
Climate misinformation
Corporate communication
Political economy
The relationship between science and policy
Her expertise helps explain not only what scientists know about climate change, but also how that knowledge is communicated and contested.
Naomi Oreskes and ExxonMobil Research
Oreskes has also investigated the historical record of corporate climate communications.
Her research has examined what companies such as ExxonMobil knew about climate change and how their public communications compared with internal scientific understanding.
This work contributed to broader public discussions about corporate responsibility and climate misinformation.
Her research has appeared in major newspapers and scientific publications and has been cited in legal and policy debates surrounding climate accountability. Harvard lists her work on ExxonMobil's climate communications among her public scholarship. (histsci.fas.harvard.edu)
Naomi Oreskes Public Speaking
Oreskes has become a prominent public speaker on science and society.
She has spoken at:
Universities
Scientific conferences
Government institutions
Climate events
Public forums
International organizations
Her TED Talk, “Why We Should Trust Scientists,” helped introduce her ideas about scientific consensus and public trust to a global audience.
Her speaking style often combines historical examples with contemporary scientific debates.
Naomi Oreskes and Science Communication
Oreskes believes that scientific communication is not simply about presenting facts.
People need to understand:
What the evidence means
How scientists know something
Why experts disagree sometimes
Why some uncertainties matter more than others
How scientific consensus is established
Her work therefore sits at the intersection of science communication and public policy.
Harvard's description of her work emphasizes her role as a leading voice on the role of science in society and anthropogenic climate change. (eps.harvard.edu)

Naomi Oreskes Struggle Story
Oreskes' career contains several important struggles.
Entering a Male-Dominated Field
When she studied mining geology, women were still uncommon in the profession.
She was one of only two women in her graduating geology class at the Royal School of Mines, according to Stanford's account. (sustainability.stanford.edu)
Proving Herself as a Field Geologist
In Australia, she was often the only woman in her exploration group.
She worked in remote environments where she had to establish herself professionally in a male-dominated industry.
Changing Academic Fields
Moving from geology into history of science meant entering a different academic world.
She had to build expertise across disciplines rather than remaining within a conventional scientific specialization.
Becoming a Public Target
Her 2004 climate consensus paper dramatically increased her public profile.
She later described how the paper changed her professional life because she began facing attacks and criticism.
Instead of retreating, she investigated why the attacks were happening.
That investigation eventually helped lead to Merchants of Doubt. (timeshighereducation.com)
Naomi Oreskes Success Story
Naomi Oreskes' success comes from doing something relatively uncommon:
She connected disciplines that are normally kept separate.
She combined:
Geology + History + Philosophy + Environmental Science + Politics + Public Communication
Her geological background gave her scientific credibility and firsthand experience.
Her historical training allowed her to investigate how scientific knowledge develops.
Her work in science studies helped her understand the institutions surrounding research.
Her public communication skills allowed her to bring those ideas to millions of people.
That combination made her one of the most recognizable historians of science working on climate change and public trust in science.
Naomi Oreskes Current Work
As of 2026, Naomi Oreskes is a Henry Charles Lea Professor of the History of Science at Harvard University and an Affiliated Professor of Earth and Planetary Sciences.
Harvard lists her primary research areas as agnotology, political economy of scientific knowledge, Earth and environmental sciences, science and technology studies, and the history of climate-change disinformation. (histsci.fas.harvard.edu)
She continues to write, teach and speak publicly about:
Climate change
Scientific consensus
Misinformation
Science policy
Environmental history
Public trust in science
Corporate influence on scientific debates
The history of scientific knowledge
Her work continues to be relevant as societies struggle with misinformation and debates over evidence-based policy.
Naomi Oreskes and Geography
Naomi Oreskes' work has an important connection to geography because her original academic field was Earth science and geology.
Geology is fundamentally concerned with Earth's physical history.
Her research into plate tectonics, continental drift and Earth sciences connects directly with understanding:
Earth's structure
Continents
Geological processes
Natural resources
Environmental change
Climate systems
Her later work expanded this perspective.
She began studying not only Earth itself but also how humans produce knowledge about Earth.
That makes her career especially interesting from a geography perspective.
She moved from studying the physical planet to studying the scientific institutions and social processes through which people understand the planet.
Naomi Oreskes and Women in Science
Oreskes has also contributed to discussions about women and gender in science.
Her own career provides a useful example.
She entered geology when women were still underrepresented in the profession.
Her early experiences helped shape her understanding of how social expectations can influence scientific careers.
Her scholarship has also explored the historical role of women in science and the ways gender can influence recognition and professional opportunities.
Her career demonstrates that scientific achievement is shaped not only by individual ability but also by the institutions and cultures surrounding scientific work.
Naomi Oreskes Personal Life
Naomi Oreskes has generally maintained a relatively private personal life while remaining highly visible professionally.
She has spoken publicly about motherhood and how becoming a mother changed her life.
Her family background also included strong connections to science and education.
However, her public identity has primarily centered on her scholarship, teaching, writing and public communication.
Naomi Oreskes Net Worth
Naomi Oreskes' exact personal net worth is not reliably established through authoritative public financial records.
Online estimates should therefore be treated cautiously.
Her career has primarily been based in academia, research, writing and public scholarship.
Her influence is better measured through her books, research, teaching, awards and impact on public understanding of science than through financial estimates.
Why Naomi Oreskes Is Important
Naomi Oreskes is important because she asks a question that is becoming increasingly relevant:
What happens when scientific knowledge enters the political world?
Science can produce evidence.
But evidence must then move through:
Universities
Governments
Businesses
Media
Courts
Schools
Political institutions
Public opinion
At each stage, information can be interpreted, challenged or distorted.
Oreskes studies those processes.
Her work therefore helps explain why scientific facts can sometimes be widely accepted by experts while remaining politically controversial among the public.
Naomi Oreskes Legacy
Naomi Oreskes' legacy is closely connected to the relationship between science and society.
Climate Science Legacy
Her 2004 research helped quantify the scientific consensus on human-caused climate change.
History of Science
Her scholarship has helped explain how scientific knowledge develops and why scientific theories sometimes face resistance.

Final Words
Naomi Oreskes' story is unusual because it began with rocks and ended up at the center of one of the world's biggest debates about science and society.
She started as a geologist.
She worked in the Australian outback.
She entered a profession where women were still rare.
Then she changed direction.
Instead of studying only the physical Earth, she began studying how humans understand the Earth.
That shift transformed her career.
Her research into continental drift showed how scientific ideas can face resistance.
Her 2004 climate research helped quantify scientific agreement about human-caused global warming.
Merchants of Doubt investigated how doubt can be strategically created and communicated.
Why Trust Science? explored why scientific knowledge deserves public trust.
And her later work has continued to examine misinformation, politics, business and the social construction of knowledge.
Her greatest contribution may therefore be a simple but powerful lesson:
Understanding science means understanding not only the evidence, but also the people, institutions and societies through which that evidence reaches the world.
In an age of climate change and information overload, Naomi Oreskes' work reminds us that knowing what is true is only part of the challenge.
The other challenge is understanding why people sometimes refuse to believe it.
