📖 Overview
William Ruddiman is a paleoclimatologist and Professor Emeritus at the University of Virginia who has made significant contributions to the field of climate science. His research focuses on Earth's climate history and human influences on climate change over extended time periods.
Ruddiman is best known for proposing the early anthropogenic hypothesis, which suggests human influence on global climate began thousands of years ago through agricultural practices, rather than at the start of the Industrial Revolution. His 2003 paper "The Anthropogenic Greenhouse Era Began Thousands of Years Ago" sparked considerable scientific discussion and debate.
His work spans geological timescales, studying how Earth's orbital variations affect climate cycles and how plate tectonics influence atmospheric CO2 levels. Ruddiman has authored several influential books including "Earth's Climate: Past and Future" and "Plows, Plagues, and Petroleum," which examine the long-term relationship between human civilization and climate change.
Through his career as both researcher and educator, Ruddiman has contributed to the understanding of Earth's climate system through studies of marine sediments, ice cores, and other geological evidence. His work continues to influence discussions about the extent and timing of human impacts on Earth's climate system.
