Paul F. Hoffman

Paul F. Hoffman is a prominent American geologist known for his contributions to Earth sciences, particularly in understanding the history of the planet's climate and tectonic processes. He is renowned for his research on the geological history of the Earth, including the study of ancient ice ages and climate changes over millions of years. Hoffman's work has significantly advanced our understanding of the relationships between geology and climate, influencing both scientific research and public policy regarding climate change. His most notable theory is the "Snowball Earth" hypothesis, which suggests that the planet experienced extreme ice ages covering much of its surface.
