William D. Sellers

William D. Sellers (18 August 1928 – 27 August 2014) was an American meteorologist, climate scientist, and pioneer of climate modelling. He created one the earliest climate models and was one of the first scientists to recognize the effects of CO2 in the atmosphere on the Earth's climate. He published the textbook "Physical Climatology".

Biography
Sellers was born in Culver City, California on August 18, 1928. After receiving his bachelor's degree from UCLA he earned both his master's and doctorate degree in Meteorology from Massachusetts Institute of Technology. His thesis adviser was Edward Lorenz. In 1965 he published the book "Physical Climatology". Celebrating the books's 25th anniversary, J. Graham Cogley wrote of Sellers and Russian climatologist Mikhail Budyko's work: "'These works have been tremendously influential upon the thinking of most climatologists, and have been invaluable in explaining the atmospheric engine to several generations of students. Most of the changes which we expect in our world in the near future will involve some aspect of physical climatology.'"As Professor Emeritus at the University of Arizona, Sellers retired in 1997.
